Title: I am building something ambitious
Post by: Granny Gremlin on January 30, 2018, 01:05:59 PM
Moving on from pedals to something else I have always wanted.... and then I had to make it even better/more what I want. So it's a total scratch build.  Because I did not have quite enough projects on the go.

Here's a teaser (I might be a bit with this one; about halfway done):

^ DIY acid etched BTW (sparkle clearcoat - looks better IRL)

Let me guess. Your take on this?

No wait a minute. Land of bacon is south of your border.

(Seriously I'm very curious.)

Uhhmm, yeah the yanks have something they call Canadian bacon right? Otherwise maybe a domestic affair, Traynor-esque perhaps?

The other one.

Hmm, the other one would mean Yorkville to me, but they are essentially the same company right? I bet it something more obscure then.  :vader:

Nope: Yorkville = Traynor (like litterally).  The other one.

Garnet?

Ding Ding Ding

(though, to be fair it is a modified Fender design, which I am further modifying)

Garnet rings a bell but I woud'nt have known the country of origin. Looking forward to updates to come.

Didn't Garnet build some of the Gibson Lab series amps?

Be sure to include three inputs.

What's it going to be like?

Does it go up to 11 ?

At least 13.

I am building one of these:

Which is basically a Champ with a line out to feed another amp; an OD preamp sort of thing (but can still use it as an amp too).  The main change I am making is adding the infamous (up here anyway) Stinger fuzz circuit (as found on the larger Garnet amps in the early period) ... and relay switching for general bypass as well as the Stinger.

Queue Uwe with the Randy Bachman jokes.

What Randy Bachman jokes...?

We don't need Uwe to make any jokes (though I love his wits) when Randy himself is being funny enough for himself sharing his . Out of curiousity I did some read up on Garnet and its Randy Bachman history quoted by the man himself (which is entertaining if you know the technical side of a tube output stage that is):

Gar and I developed this unit together back in '65-'66. Growing up playing violin, I loved the sustain, especially of a viola or cello. So early on in the mid '60's, I found out that by plugging a small amplifier into a bigger amplifier, I could get this sound. Now I was taking the power out, which normally would go to the speaker and plugging it into the input of another amp. The result, for a few short minutes was a cool, great new sustained sound. Gar Gillies had a tv/radio repair shop, was a cool musician, and I wasn't embarrassed to take in my amps, which were literally burned by the power misuse; fried, to say the least. Gar asked what the heck I was doing, and when I told him, he said, you're insane to do this, its very dangerous. So he offered to help me do it a safer and less destructive way. Gar proceeded to build me a tube pre-amp, which when put into another amp, got me the desired sound.

I've always been struck by the guitar sound of American Woman but never investigated what equipment was involved making it. This makes your project even cooler Jake.

Yeah... I've only ever actually heard that story as told by Gar Gillies; basicially the same but with more explatives.

Anyway, I have learned that power tube (tetrode/pentode) distortion is what I like best - e.g. all my favorite mic preamps have a pentode in them, not just the same old 12A whatevers.  Also the key is not driving the snot out of a triode but overdriving multiple cascaded gain stages.  Tet/Pentodes get you there in fewer stages than triodes - dunno why, they just do.

The Herzog, being the Champ circuit, has a 6V6 tetrode in it (and you can dime it - the line has an attenuator).  Adding the Stinger fuzz puts another triode as well as another pentode (6AN8 tube, which I love the sound of - I have other gear using those) in the circuit so I am really thinking this will be the one; my ultimate dirt machine.

Most interesting.The relay switching sounds like a good idea too.When i lived in London i ran the line(attenuated speaker)output of my laney lc15r in to a jcm800 marshall,That was a great guitar sound!
