reverse boosting

Working on the fuzzwar and there have been some issues with transistors.  So i've been messing around with the reverse booster and came up with something that works pretty stable for the 2n5089s that I have.

I think the 51K is alright so far, I think that a 10k instead of the 51k is better for impedance, but 51k is a lot louder at this point and gets close to the sound of the 7 transistor fuzz war.

I'll have to see how they stack together though, with both the 10k or 15k the bass frequencies clip more. But obviously not as much as the 51k.  At 100k, theres some gating and the start of that velcro sound, 180 is entirely gated and velro-esque...

Getting back into screen printing

Well its been a while since i screen printed anything.  I've been working on a design for quite some time and trying to get the circuit to match. I know I know, I really should figure out the circuit first before making artwork for pedals, but this time I'm going to do the right amount of planning!

So this is my heavily modified big muff design with different clipping options.

Its not my finest, I goofed on the upper right hand corner.  The screen had a lot of holes in it and I just left it.  It looks OK enough and I'm just trying out some ideas at the moment.  I'm going to put the 9V and INPUT and BYPASS in red , and I'm going to try to put an image on the side to take it a step further than I usually do.  But this will require a large amount of back and forth in terms of clearcoating, drying and screen printing.  Ah well hopefully its worth it.  I'll keep you guys posted in terms of what the result slowly develops into.

The circuit was previously housed in this

But I kind of botched that enclosure and right now a friend is borrowing it, and since I had another enclosure that I've just been sitting on for a year, I wanted to try some more artwork out..
Here was an earlier version with the red knobs...
