So this is what happens when you're the type that is easily influenced by your peers and highly open to suggestions.....you wind up with a big ol'pile of Russian Ge transistors to build fuzzes that you really don't know how to play
In all seriousness, I'm quite surprised that I've been able to get these from the Ukraine seller on eBay given the situation over there. They took about a month to get here but I'm pretty flush with an assortment of transistors with an assortment of gain ranges.
Following the footsteps of my "fuzz enabler" @szukalski, I built the Gnat yesterday afternoon and was playing around with some different value components.
I landed on the following:
Q1 - GT308V - Hfe 59
Q2 - MP42B - Hfe 85
Q3 - P28 - Hfe 143
Ge diode - G223 Vf ~.334
Sounds pretty darn awesome to me. I have no clue if it sounds anything like the original and not sure I really care.
Still figuring out what the controls do. From my extremely limited understanding of reading circuit schematics, it looks like Sustain and Balance effect the bias of Q3?
Somehow the Ge diodes plays a part in this as well. I can get from fuzzy to really spitty and snarly with the controls.
I may go back and revisit some of the earlier Ge fuzzes I've built now that I have more transistor options to mess with.
Might try to post a demo later today once I get my new guitar project put back together. (Lot's of multi-tasking this week
Snapped a pic this morning just as the sun was coming in my office window. Really sets off the Tayda Brown Sugar Glimmer color. Really digging some of these new colors from Tayda.
Oh and of course, lots of judicious finagling to get this into a 1590B.
