The Bass Zone / Just a check in to say howdy
« on: August 10, 2014, 06:12:37 AM »
Been awhile since I actually posted onsite but thought I should say hello.

Still fighting the health issues but I have come to accept what is but the prognosis is fair and not immediately or tragically eminent so be at ease brothers.

I have been busy and I do not like defining my life around health issues, but I till have time in the day to accomplish what pleases me. My grandchildren are growing, my children are safe and I love cooking, playing bass in my bedroom and working on my hotrod.

Took off for Illinois last weekend to get a cabinet that has been set aside for a long time. Made a 1000 miles in 36 hours. Not too bad for a bucket list practitioner, lol.

The cab (sorry about the picture quality!) got overhauled with a cleaning, a new grill to replace the old one that was installed 90 degrees wrong, a repair of all loose screw holes, a regluing of some joints and a new wiring loom.

Ordered a new Weber 15" bass speaker for the 15" tone ring cab. Still have the Celestion G12T-75's for this cab but am thinking of the GOT approach and going to Eminence Legend's for this 212.

I will post more as soon as I can but "Hello" to all the brothers.

The Bass Zone / RA Woods Fender cabs
« on: March 17, 2014, 02:02:45 PM »
This last year I took delivery of a Fender tone ring reproduction cab made by Rick at R A Woods. I love it. Rick is having a bit of a hard time now. I just got off the phone with him. He just finished two orders for 15" cabs and is taking orders for more. I know he can use the work.

If this is not appropo then delete this thread. Told Rick I would post it.

The Outpost Cafe / sniper sighting
« on: May 22, 2013, 12:40:27 PM »
just wanted to pop in and sy hello to the gang. had a bit of action here in Missouri and it is kind of leveling out. got up here for the grand kids birthdays and traveled to get my new tone ring vcab then never made it back to Texas.

had a hosp stay in Jan that lasted over a month and ended up losing most of my kidney function. I am on dialysis three times a week now so traveling is sort of out. I am moving back to Missouri and a good friend (Dale) my Marine buddy, is going for my things soon. I have most of my equipment in Pecos. lost abot 55 pounds in weight and feel good. had a small surgery on my arm to make the veins pop ouot so I can get this catheter in my chest out. had it in since Jan.

on my travels I dropped off my black Bassman head to get new blonde Tolex applied and have my mid 60's 2-12 cab restored and RA Wood speaker cabs. should be done now, talked to Rick last week. I have been trying to read the BOP but not a lot of computer time with everything going on. hope I get on a transplant list so any extra good kharma would be appreciated.

be well all of you and the best to all of you.

love ya all,

your bro,

CW (Sniper)

"IN MEMORIUM:
SSGT Oliver Clifton Stamps, died under my care in the Republic of Viet Nam on or about 08 January, 1970.

He was a great leader of men. I was a Navy Hospital Corpsman assigned to his unit.

He was mortally wounded early in the day while he was disarming a booby trap.

He succumbed to his wounds in transit to the 1st Medical Battalion on a Medievac Chopper while I was at his side.

I was the only medical corpsman to come to his aid after he was wounded. I and the Marines with me tried feverishly to save his life but ... in the end, we could not.

There isn't a year that has passed that I have not remembered him on the anniversary of his death.

He had a love for his family. A warm gentle smile and a knack for leading his Marines.

He is sadly missed.

Sincerely,
Vern F. Bosley (HM2-USN)"

Vern is my self-adopted big bro and my hero ... Sniper.

Bass Amps & Effects / choke values in bass guitar amps
« on: September 17, 2012, 04:50:10 AM »
doing more research on the Sunn 200S amp, i realized i need to know a little something about choke values in amplifiers. i found this article on the 300guitars.com site. it explains the choke usage very well and i thought i would pass it on.

"Chokes: What Are They? What Do They Do?A choke is an iron core inductor used in the power supply of a guitar amp as a filtering element. Looking a lot like a transformer a choke only has two leads coming from the housing. They are designed to block AC while passing DC. Their purpose in guitar amp filter supplies is to smooth out the ripple in the rectified DC.

In some guitar amplifiers a high wattage resistor is used instead of a choke. A resistor in place of a choke saves money and to a certain degree manufacturing time.  The drawbacks of using a resistor is there is more residual AC ripple in the power supply after rectification resulting in a little more background hum in your amp. One example is the 5E3 Fender tweed Deluxe. It does not have a choke in its filter supply. (Nor does the Bassman 10 amp have a choke filter. ... Sniper).

Chokes have ratings of voltage, DC current ( measured in milliamps), resistance (measured in ohms) and inductance (measured in Henries). A typical choke for a 50 watt guitar amp is rated for about 500 volts and 50 milliamps. The resistance measures in the 250 ohm range and inductance between 10 – 20 Henries. The inductance of the choke coupled with the capacitance of the filter capacitors determine the bass response of the amplifier. A larger inductance value choke will have a better bass response than a smaller value choke. An amplifier with a power supply choke will have a deeper, crisper bass response than one that uses a resistor instead of a choke.

To sum up in simple terms using a choke in the filter supply the result is less background hum and cleaner, better bass response. Using a resistor manufacturers save time and cost and there is a bit more background hum and a looser bass response."

Bass Amps & Effects / possible cap upgrade for Sunn 200S
« on: September 15, 2012, 12:32:47 PM »
as most of you know i am a junkie. my father owned an automotive salvage yard and thats where i get it from. i am always looking for something i can salvage or rebuild into what i want.

my present project is getting myself a 200S amp and none seems to be available at a decent price so i bought a salvageable Dynaco Mark 3 amp and am prceeding to build a 200S clone of sorts using the money i recieved from my little foray into the Weber kit experience. they had a sale on amp kits and the software on their site let me buy a 450$ amp kit for 170$. i could not pass that up but in all honestly i didn't know the software was screwed until i made the purchase. it turned out to be the wrong kit as their listing was wrong and i was thinking i was getting the four power tube 5e7 kit instead of the 5e8. this was the one i was selling and i made a few bucks on the resale. they have since repaired the glitch in the software and made the correction on the listing. i was just the lucky one who stumbled onto it.

but to continue with my post:

in researching the amp i found that a weak point in the mark 3 and probably in the 200S is the cap can. it seems as the voltage in the mark 3 surges to 600 volts when the amp is turned on. for 200S users this is usually not a problem if one used the standby switch diligently. if one does not it can be a problem as this overrides the capacity of the cap cans rating of 525 volts and brings an early demise to the can.

at one site i found a can that is rated for 550 volts with a 600 volt surge capacity. it has the correct MFD values in four caps inside one can.

http://www.dynakitparts.com/store/product.aspx?id=312

this cap can can be wired correctly for a 200S and one might keep it in mind for future reference if you have any problems with your amp. as the 200S is based on the mark 3 i thought i would pass this on.

Gibson Basses / EB3 wiring harness by Rothstein Guitars
« on: August 17, 2012, 07:47:42 AM »
http://www.facebook.com/photo.php?fbid=10151177791286882&set=at.10150343646511882.397335.317724746881.632781710&type=1&relevant_count=1&ref=nf

two years ago i had Curtis make me a choke and directed him towards the spool to use to make it. then i sent him a choke to use for a model when he wound the spools. now Rothstein is making a wiring loom (sorry i could not post a picture but photobucket is throwing a tantrum!) that looks and sounds like it may do the trick.

"1. The tone pot for the neck pickup is a push/pull that allows you to choose between traditional treble roll-off, vs. diode clipping (ala Jack Bruce). I found a particular type of Germanium diode that works extremely well. It sounds killer.

2. I'm using a choke bypass in the circuit. When I looked that original design it seemed to me that the choke is only supposed to be "live" in 1 of the 4 positions, but it seems like it is actually in the circuit more than it should be. So I tweaked a bit so the choke is 100% out of the circuit except in the 4th position.

As far as components, they are very old school featuring a Curtis Novak vintage reproduction hand wound choke, along with CTS pots, MOD paper-in-oil caps, carbon comp resistors, and vintage style cloth wire.

I will try to get some sound samples up within a week or so....stay tuned!!"

Bass Amps & Effects / 15" tone ring cab
« on: July 07, 2012, 08:02:47 PM »
just ordered a 15" tone ring cab from Rick at RAWoods in Peoria Il. Price seemed right and I traded a AB165 blackface chassis and cab (no transformers) in for a partial credit. man am i excited, will post pics when it gets here around Septemberish. This is going with my
Bassman 2-12 bottom and my Bassman 10 in the Bandmaster reverb cab. ;D ;D

i just got off the phone with Hipshot and ordered a new two stud supertone for my reconstruction on the crispy crittered '66. Hipshot told me that for almost a year now they hae been making the two stud bridge with an elongated hole to address the earlier (angled) stud mount for the pre 67 Gibson basses.

one of the problems he said i might run into buying from a distributor is them having old stock types that do not have the elongated hole to address this problem. i ordered one from Hipshot directly.

this should be a viable solution for those of you wanting a newer type bridge to work on your EB2's. just be aware that the Hipshot bridge still sets on the wood of the body and might make an impression when mounted.

when it arrives i will let you know if it works for sure on the older angled stud mounts.

almost forgot, FWIW Hipshot will make, on special order, tuners for the open bass/slothead type head (think 70 and 71) as they have to have longer shafts for the strrings to wind around and they will reach so the shafts will be supported by the center section of the head. this will be no extra charge to the customer but will require a direct purchase from Hipshot. i talked to Josh. this modification will only be available on thier ultra lite tuners HB6 series.

Bill's Shop: Projects, Mods & Repairs / upgrading the varitone plate
« on: June 19, 2012, 12:57:18 PM »


this is how it is going to look, a very close reproduction. i am also working on a 335 6 position plate gold background with black numbers.
i have to redesign (think resize) and make a new trimming die.

aside from the final trimming to size and the hole in the middle, see if you can spot a goof on this proof. the lousy finish on the proof is the plastic covering i use to protect the plate while working on it ... and that is NOT the goof!
