On the bench this week till the Ultimatum arrives for tracing - Stereophonic Gizmotronic Symphonic Harmonic Perambulator
Working on a commission build for a client who want a one-off build of a stereo-dual chorus with a shimmer verb follower on each channel. It will be using 4 modified GuitarPCB "Mini-Me" chorus circuits and 2 PedalPCB 'Pythagoras' project boards with custom SpinCAD Designer/SpinASM rolled FX patches. Each stereo chorus pair will tied together at the LFO so they can be independent or synchronized with both 'depth' & 'rate' mods. Each chorus section will have independent controls. The two Pythagoras boards will be synchronized under a set of dual-gang pots & patch selection actuator. The L & R outputs will be pushed thru a pair of balanced XLR driver boards.
The fun part will be finishing the rack box faceplate.

I have a Fuzzrite in the works. Trying to make it quieter. Here's a few observations:
It sounds thinner and buzzier into a clean amp, fatter into a tube amp at the edge of breakup. So much so that taking out the 22k resistor doesn't make that much of a difference whereas it's pretty big with a clean amp.
A 470pF cap from input to ground gets rid of the radio for the most part. Still noisy though.
Adding a 100r resistor in series with the input doesn't help. It does suck high end.
I went from 2N3904 with a hFE of 192 to 2x 2N3692s at 64. Slightly less gainy and trebly of course.
Adding 100r-200r resistors to the emitters to ground didn't make much of a difference.
Noise is part of the deal here. It isn't as loud as a fuzz face. It's also scooped in the mids so you have to crank the volume and live with hiss.
I tried adding the PW knob from the Fuzzolo but it didn't work. I added it to a Fuzz Face but it oscillates. I suppose the 2.2k to ground on Q2e must be there also.
More breadboarding to come.

YATS now with built in CHUG CHUG mode by all the Videos available, No Thanks!!!!You're not trying to suggest this is a Tubescreamer are you?

It seems unlikely, but for some reason I have a hunchYou're not trying to suggest this is a Tubescreamer are you?
