Fender Basses / Building a Jazz from Fender parts
« on: July 25, 2020, 02:47:23 PM »
I've noticed that Fender have been selling both US and Mexican bodies and necks for some time. Oddly they have a line of roasted maple necks that seem to be exclusively available as aftermarket parts. I know that buying new parts is probably terrible value for money overall, but I'm going ahead anyway.

I'm always in the market for a Jazz Bass, but find it hard to bond to them. I'm giving it another shot, and I will document the process here.

As a rule of thumb I buy Mexican Fender basses second hand, and usually strip out the stock pickups and wiring and replace where necessary. I also tend to level, crown and polish the frets as well. However Covid-19 seems to have reduced the pool of available instruments, so I can't snaffle up a used bass at the moment. Beyond this, my preference is for Mexican basses built during the era they introduced the black headstock decal (maybe 2010s?) up until they revised the lineup as the 'Player Series'. In terms of the used market people tend to want the same money for a dinged up 1990s corner-cutter Mex bass as they do for a mint 2019 bass with the plastic film on the pickguard. There is no consistency in the price of used MIM Fender basses in my experience, and I'm shooting for a fairly small niche where I think they were at their best.

With all of this in mind, I've just bought a black Jazz body and maple Jazz neck online. I have most of the other bits I need already. Watch this space!

Bill's Shop: Projects, Mods & Repairs / Tokai EB-3 improvements.
« on: April 28, 2020, 12:49:59 PM »
My Tokai EB-3 is copy on the bench! This is my stuck-in-the-house bass project for the next little while.



The combination of nickel bridge and chrome pickups will have to do for just now...  :o

There are bits of the bass that are pretty good, and bits that are a bit off the mark. The model is an 'SGB' something... different Tokai EB-3 models have bolt-on necks or control spacing that is like an early Gibson EB-3. I have plans to modify this bass a bit, which I will document here.

firstly, I've leveled the frets. They were generally level, but oddly the 10th and 11th frets alone were much lower than the rest. I'm not sure how that might have happened, but I remedied it. Oddly the fretboard is 'rosewood' according to the literature, but it has a walnut colour. It also hasn't taken my usual boiled linseed oil finish very well, remaining tacky and barfing oil out of the deepest pores after a couple of days.


I didn't entirely like the stock pickguard. It was quite warped, and seemed to have too much meat down by the controls but end a bit short by the treble cutaway. The screw at that end of the pickguard is also badly off-centre. I decided to prototype some pickguards to try and come up with a revised fit that worked with some of the stock screw-holes in the body but looked a bit more accurate.



I extended the horn on the pickguard and made that end of it a bit chunkier. I took some meat away from the section down by the controls. I added a new screw hole and rounded the shoulder of it where it meets the neck, a la '60s Gibson basses. I'm swithering about making a banana-shaped tug bar to mount on the pickguard, but this might be a step too far.



I can't find 5-ply pickguard material in the UK, so this is 3-ply like an old EB-0. I've not cut the route (a mud hole?) for the pickup yet as this is being swapped.



No decimal place. This is the DC resistance in ohms. Very odd.



Not a whole lot of magnet on this pickup either.


As for the bridge pickup, I ordered a Gotoh replacement, but this won't even begin to fit the stock pickup ring. The pickup ring on this bass is 100 mm long, and the stock bridge pickup has fairly unique dimensions (70mm x 32mm). This is close to some Chinese 'minibucker' or 'Firebird' pickups kicking around. I'm prototyping an adaptor pickup ring that would allow the Gotoh pickup to be used, but it might look a bit goofy having a small pickup mounted to a vast pickup ring.

The stock bridge pickup itself has a DC resistance of 5.5 k ohms, and a strong magnetic pull down the middle of the case. I wonder if it is in fact a fat single coil hiding under the cover.

Other Bass Brands / Tokai EB-3 copy.
« on: April 16, 2020, 09:55:06 AM »
This was a birthday present for myself!

I've been on the hunt for something with a mudbucker down at the end of the neck for a while. My 4003 and Starfire both have true neck pickups, but neither has a hot, punchy pickup in that spot. I was looking at basses to modify, when I stumbled up on this! Its red, SG-shaped and doesn't need any routing or hacking about.



I'd previously been checking out a used, and abused, longscale Epiphone EB-3, but I didn't like the block inlays or the visual impression of a small SG body on the end of a long neck. Plus, the neck angle wasn't quite right as the strings were tickling the bridge pickup, which was about as low as it would go in its trim ring.

From some Googling, it seems that Tokai make/made a few EB-3 copies. One was a bolt-on necked bass. One had a weirdly short pickguard. One had a wider knob spacing like an early EB-3. I'm not sure what model this is, but it has a set neck and the pickguard is almost the right shape. Unfortunately the pickguard isn't quite flat on the top of the bass, but I plan to cut another with a 30 degree bevel.

Just to clarify, this isn't an old 'lawsuit' instrument but something built in the last few years, most probably in China. I think it shares a lot of DNA with Epiphone EB-0 basses.





Headstock has a cheeky open-book shape and the tuners have nice small paddles, rather than the huge cloverleafs that make some EB-0/SG/EB-3 basses look a bit silly. I have some Wilkinson tuners of the same design if I need to upgrade.




The pickups are a mixed bag. The 'mudbucker' is similar to an Epiphone EB-0 pickup I had for a while. Specifically it measures 1.2 k ohms on the multimeter, as some Epiphone EB-0 pickups do. Tonally it is a dull pickup with low output but very little treble as well. I will probably replace this with an Artec sidewider.

The bridge pickup is like a Firebird/minibucker pickup and has a bit more snap to it. It meters out at 5.6 k ohm, which is still a bit low for a humbucker. It is also very slightly microphonic and slightly more susceptible to interference. It is mounted to a low, flat trim ring. I will probably swap this out with a Gotoh/All Parts repro EB-3 bridge pickup.


Tokai fitted 34'' roundwounds to this bass and simply chopped them down to fit. This makes the strings sloppy, buzzy and very uneven. I will probably go with some sort of black tapewound strings for maximum British Invasion tones.


As for the wiring, the bass is currently configured like an SG guitar. Each volume acts as a master in the middle setting. I'm planning to replace the pickup switch with a 6-way varitone control, using the primary of a small transformer to act as a choke. I plan to wire the bridge pickup with a treble bleed (4.7 nF cap with no resistor in series). The neck pickup tone control is getting swapped for two schottky diodes in parallel, back to back.


19
I've seen a lot of displeasure directed at the SRB-1 pickup set. Yet they seem to have some fans on here?

In short, Seymour Duncan claim that the bridge pickup doesn't fit a standard Rickenbacker pickup ring, yet I've seen photos online that suggest they do.

I have a 4003 bass, and pickup ring, and I can fit a generic hotrail guitar humbucker through the aperture of the ring. Were I to screw this pickup to the carriage assembly I could use it as a bridge pickup, and it looks no smaller or skinnier than the Seymour Duncan pickup.

Any thoughts?

The Bass Zone / What is this bass???
« on: November 01, 2018, 02:50:05 PM »
I've been listening to the band Curved Air a lot recently. Admittedly I don't like the following song, but I have been trying to work out what the bass is!



To get around the dodgy visuals, I inverted the colours.




It looks a bit like an EB-3, only with two identical single coils, a two-piece bridge, and a split diamond headstock inlay. I don't think it is a Gibson. It looks like a Greco headstock, but I can't tie it to any of their models. It also says 'Framus' to me, but again I can't pin it down to a specific model.

Bill's Shop: Projects, Mods & Repairs / DIY pickguard
« on: September 24, 2018, 09:30:24 AM »
So I have a couple of Fender PJ Mustang basses. Aftermarket pickguards for these are scarce and expensive! I was looking for a tortoiseshell example, but these seem to be especially expensive. I wanted my white Mustang to look a bit more vintage to suit the aesthetics of my band, and to make me feel less bad about the MIJ Mustang I sold on a while back. That bass looked cool, but the tone was too delicate for me. My white PJ Mustang runs on a set of Dimarzio pickups which are more what I want to hear!

I've made a few pickguards before now, but I've finally got it down to something approaching a standard process. The obvious solution is to make an MDF template and use a router with a nice sharp 45-degree bit. Get the whole thing carved out in the time it takes you to read this sentence!

 I have none of the above, so I have to use hand tools.



I cut out the basic shape using a coping saw. I dial in the shape closer using a rasp, flat, rounded and circular files, and sand paper.



The trick is to sneak up on the lines, which I draw on the pickguard material (silver Sharpie for dark pickguards, black Sharpie on white material). I've seen a lot of DIY pickguards online that simply look rushed and ugly, probably because the builder was in a hurry to get the thing done.

The cutaway outline is the same diameter as a jar of instant coffee (I trialed a lot of jars and tins in the kitchen), so I stuck 180 grit sandpaper on this and had at it!



The only truly problematic area is around the control plate. However I have two WD Music pickguards in my possession that are no better at this area:



I hand-turned each countersink for the screws. I've found that you can't do this cleanly enough with a hand drill.

The 45-degree bevel is carved on last. I colour the outside of the pickguard with black sharpie and then carve the bevel with a Stanley blade. I carve until the white of the lower layer appears from under the Sharpie. I also keep an eye on the black line in the pickguard material as this has to look even.

Gibson Basses / Strange EB-0 on Reverb
« on: August 02, 2018, 07:26:02 AM »
https://reverb.com/item/10931087-gibson-sg-bass-eb-ebo-project-luthier-1965-1966-1967-heritage-cherry

So this guy is up on Reverb. Looks like an EB-0 with two additional controls and a hole for a pickup selector switch. In the electronics cavity there appears to be a choke as well.

I'm guessing the wiring is modified as the insulation is many different colours. The ugly common ground blob doesn't look factory original either.

Did somebody spoon the best of an EB-3 into an EB-0?

I enjoy guitar archaeology. I like seeing a guitar and trying to work out what has happened with it, and what needs to be done to it.

As per my NBD thread I picked up a used but not abused Dearmond Starfire at the weekend. If I bought it from Reverb it would probably be called a 'Barn Find' instrument. The guy who sold it to me bought it new, used it in a funk band, and then hid it in the attic for years as he moved back to 34'' instruments. As such it is clean, but its time in storage has introduced some issues.


The bass has one scratch in the top which I plan to infill with superglue, level and polish out. The clear coat on this is poly, which is pretty thick. This means I should be able to level, blend and polish everything in. I'm guessing a screwdriver or other tool slipped over the surface of the instrument near the selector switch. Oops!

Beyond that it needs a new wiring harness, a fret dressing, and a general clean and polish. Some of the chrome work on the bridge pickup is pitted, so I can only polish what is there to be polished! The metal work is dull and smeary, but luckily none of it is scratched. The odd thing is that the black saddle adjuster screws and springs have an odd white bloom on them. It is a bit like a superglue bloom, or the result of some old plastic off-gassing. I can't find the source of this, but it has ruined the black finish on the screws.

The electronics are the weak link in the chain. I've seen this before on Korean instruments; you get amazing build quality then totally average electronics. The 3-way swith is one of those closed in box-type switches. Once they go dead they stay dead. The pots are 500k Cor-tek branded units. Nothing special, and a bit to on/off for me to bother saving them. As per some Epiphones and the like, they used a kilometer of wiring where a meter would do. There is a lot of slack in the wires in this bass.

The frets are green, and have a bit of roundwound chew as well. The bass came with astonishingly dead, low tension rounds with red silks. Maybe Rotosounds?

Green frets and ham.

Other Bass Brands / NBD: Dearmond Starfire II
« on: July 08, 2018, 12:45:21 PM »
I sold my Coronado reissue a couple of months back, but still had the itch for a big honking semi-hollow. My Jack Casady is still in need of a refinish, and my Aria TAB-66 has become a fretless Frankenstein's monster. As such, I needed a bass! I've been using two PJ Mustang basses for everything, but I've always wanted a Starfire. A Dearmond Starfire turned up locally for the equivalent of $465, so I think I got quite lucky, as I've only seen (typically rougher) examples go for more.



One owner from new, and still with the protective film residue around the neck pickup. This was his daily driver for a while, but latterly it has been living in the attic. As such the metal is a bit tarnished, and the frets are a bit green, but short of the odd scratch and one chip on the headstock it is in good condition.




Somewhat rashly I was thinking of dumping Guild BS-1 'Bisonic' reissue pickups into it, as I already have a bridge pickup, but I might hold back for the time being. The electronics didn't come out the attic storage phase unscathed; the potentiometers are very much on-off switches, and very crackly. Also, both volumes behave like master volumes in the middle setting. However the pickups sound ok. The neck pickup is very much into Chas Chandler or Paul Samwell-Smith country, and I quite like this! I'd read online that these 'Gold Tone' pickups sucked, but I haven't found this to be the case.

 I'm going to do the boring stuff and restore the electronics and improve the cosmetic condition of the finish and metal work. The frets have a wee bit of roundwound chew, and maybe need a bit of a re-crown. I will then see if it actually needs Bisonic pickups, or whether I'm falling for faddy nonsense.

Gibson Basses / Tastefully modded EB0 from my Facebook feed.
« on: April 25, 2018, 11:08:49 AM »
This bass might already be known in these circles. Anyway, I follow a page called 'Reptile Dentistry' that documents some of the cruder guitar modifications that surface on the net.

Today they posted these images!

Gibson Basses / Modded 1970 EB-1 on the Bay.
« on: April 23, 2018, 05:24:55 AM »
https://www.ebay.co.uk/itm/1970-Gibson-Violin-Bass-EB-1/202292983325?hash=item2f1999f61d:g:LPEAAOSwOJJauWVZ

There is a 1970 EB-1 with an added humbucker and control on UK Ebay at the moment. I'm not in the market and I'm not the seller. This might be of interest to people out there?

Google reckons the seller is after $2,094.14 if you convert straight across. Is this a bit steep for a 'reissue' EB-1 with non-reversible modifications? Or is this simply the 'Reverb' effect, and any old instrument is now worth $$$?

Interesting mods to this one. The execution of the control cavity extension, and the backplate, is quite tasteful! The matching speedknobs is a nice touch as well. Makes me wonder if somebody like John Birch or Dick Knight carried out the work? Not a lot of guys in the UK in the '70s doing anything like decent quality work, and this is above the 'kitchen table' quality of work that sometimes surfaces over here. In fact the recessed back plate is better than some of Birch's work as, from memory, he/they weren't up to recessing back plates back then. It looks like the cavity was extended using Forstner bits in a drill press, which is John Birch-style work.

Anyway, the mod might be ~30 years old, but I would be surprised if that anonymous black humbucker was the modder's first choice of pickup. The large chrome surround is about the same size as the neck mudbucker, so I'm wondering if the modder originally went for a double mud setup?

Bill's Shop: Projects, Mods & Repairs / Couple of Jack Casady questions!
« on: August 20, 2017, 02:14:53 PM »
So I've finally bartered, haggled and brokered myself a black Jack Casady bass!

I got it for a good price, in part because it has a couple of issues:

1) The transformer is loose within the instrument and rattling around.

2) The 3-way switch spins in perpetuity as it is somehow missing the keeper. It still has the three positions, but you can cycle through them endlessly.

In short, where does the transformer sit within the bass? I thought it might be attached to the switch originally, but from having had a look at Casady harnesses for sale it appears to be separate from the switch.

Also, can I get away with a generic four pole/three way switch or is there a space consideration? How bit a component can be fished inside a Casady bass?

Also, is there any advantage to upgrading the potentiometers, and do they use different values given the low impedance of the pickup?

Bill's Shop: Projects, Mods & Repairs / A silly idea?
« on: June 15, 2017, 02:03:53 PM »
I've found somebody selling some circa 2008 Gibson Thunderbird pickups. I'm not entirely happy with the plugged-in tone of my MIM Jazz bass. I like the girth and grind of a Thunderbird, and I love the feel and unplugged tone of my MIM Jazz bass.

A simple question really, is it worth getting my Jazz routed for T-bird pickups? I'm not after that chromed out look or anything retro like that, simply a bit more meat and muscle to my Jazz bass, while retaining the feel of it.
