This is what I'm looking into...  Only one transformer needed, instead of 1 transformer per 2 isolated outlets.  Then just connect the bridge rectifiers, voltage regulators, and filtering caps for each outlet.

Yeah that's a multiple-tap transformer.  You hook it to the mains AC, then all you have to do is rectify the taps to convert from AC to DC.

For an isolated power supply, you need transformers.  Either one with multiple taps or multiple small iso transformers.

Here's a video where I turned down the trimpot in order to get a particularly horrible overdrive sound.

"Useful" is a very subjective word 

Yea the bass player from Boris does use crushing Model T's, but he's got that white one I sometimes see in pictures on stage w/ Sunn. I like the Model T, but I feel the price is such a hype I wanna clone one. It looks like such an easy amp to build.
I've heard of VTM120. I'd glady take either one.
Is it anything similiar to a Ampeg VT-120? Cause I have one of those that I'm looking to get rid of.

Nah the ampeg is a different beast.  I love the V-series Ampegs though, especially the doom-friendly V-4.  Killer amp.
VTMs can be had for cheap still.  Kind of sleeper amps, to be honest.  Their main drawback is that they are usually biased cold, so they can sound a bit sterile unless you get the plate voltage higher.  Still, they're loud as hell and have that JCM crunch, which is all good.

Excellent score.  They're lovely in both looks and sound.

I have an FG-200 from 1972.  Fortunately they're often cheap in Japan; I got mine for 7800 yen (about $80)

That's a great choice!!

My usual amps I use are 73' Sunn concert lead (greyface), 73' Sunn Model T and 72' Sunn Solarus.
Though recently I've been using an Earth 440 Bass Producer Seriers. It's solid state, 700 watts, 2 ohm output load (4-4x12 cabs) and its got such a clean sound. Its really perfect for applying pedals.
The amp I'm most interested in now is an AIMS Eclipsor or maybe the Peavey Butcher. I've heard great things about that Peavey head being a poor man's hot rodded JCM 800. There's just too many awesome amps out there...

Awesome selection yourself.  Model Ts are huge sounding.  Every time I see Boris, I marvel at the three Ts glowing in the background.

If you're after a Butcher, also keep an eye out for the VTM120 (or VTM60, but that's only 60w. Booo) as it's the successor of the Butcher.  The only difference is that there are some mod dipswitches on the front panel of the VTM allowing you to shape the tone more  (bass boost/treble boost/mid boost).  The Butcher and VTM are super easy to mod, too.  You can take them apart really quickly.

It hasn't even been finished yet, but I'm waiting on one of these:


Roll on August, for that is when it should (hopefully) be ready to ship.

Ahhh the mysterioso SR!

I'm eagerly awaiting its availability.  Let me know if you need a beta tester

Hey everyone.

So I put some effort and work into this one this weekend off and on. I have bad news. I don't think I can do a useable layout for this project. The board would have to be quite big, and the routing quite complicated unfortunately. If it were a double sided board, it might be doable in even a 125B, but boy is this thing crazy! I have the schem file I can upload for Eagle if anyone else wants to try. I'm going to revisit this during the week to see if I can do it, but my usual style of layout may not be doable.

Thanks for trying man!

I've loved the Expandora ever since I head it on At The Drive-In's One Armed Scissor.  I remember it having a vague Rat-esque setup.  It uses an LM308, right? 

Fender Blenders are...
challenging.

Even less versatile than a superfuzz - single notes or two note power chords only.  Anything more becomes a indistinct wall of noise.  Can be heard most clearly in the middle 8 riff of Bullet With Butterfly Wings by The Smashing Pumpkins.  2:20 to 2:40 in the following video -

I took a look at that circuit, and it kinda seems a strange road to take to get a fuzz sound for me. Some of me thinks things like "if it's too complicated, it's not a good fuzz." Fuzz can be achieved with sooo many fewer parts, and I don't find many fuzzes really differentiate themselves enough for me. Interesting to see though, and there's no reason why it couldn't be done.

If you guys really want a PCB layout, I could do it for you if needed.

If you look at the schematic, you'll see that q3 and q4 are doing something special that isn't found on a lot of fuzz circuits, but actually appears in another very famous "super" fuzz

Thanks!

It was an exercise in pointlessness, though.  The wire is amazing to work with, though.  Solid-core is great, but this stuff is awesome.  The sleeving is teflon, so I could solder it on the trace side without any jacket shrinkage/melting like I get with my usual stranded hookup wire.  OTOH, if you make a mistake with your bends, straightening them out and rebending really takes its toll on the wire. 

I'll try to avoid doing this style again, but I invariably will end up doing the same.  Maybe I should get drunk again like I did with my Kokbox build.
