I just rebuilt a friends tone bender mkii i gave him almost 2 years ago. Realised component values were all over the place, my mistakes, crossing oc81d and oc75 schems it seems.. ah beer days..
Now sober as a court jury, i wrote it all down. I made some sort of magic there, the pedal is one of the most powerful mkii i ever made, most likely due to my errors.
The original had carbon comps/ carbon film resistors and dubilier, philips electros, wima caps. This has wima, roe caps and carbon film/metal film resistors but still sounds amazing.
Since he gigs a lot, i had a mission to build it like the proverbial tank.. and to shuffle the controls a bit: he wanted to have the q3 bias out in lieu of the attack pot, that he uses maxed all the time (it now sits inside as a trimmer).
I messed up the decal a bit, hope he wont mind…
1.5 volts of pure 60es fuzz.
Hot on the heels of “(i cant get no) Satisfaction”‘s success, that triggered sales of the fz1 (a product that lied for its first couple of marketing years virtually in denial), once the stock left of the original model was over, the Gibson/Maestro plants started churning out this, the fz1a.
This is a bit different in sound, still with a very distinctive vintage vibe. If you play garage, this is a must have sound, as this is the pedal thats been taken up by all those garage kids on the wake of the Stones’ USA invasion circa 65!
I didnt have any layout to follow for this, so i had to do it myself from the schem.. works great!
I used some carefully selected ac128 (sub-shit standard Tungsram), oc75 x 2 (crappy chinese Motorola) germanium trannies, NOS ICEL caps, the usual carbon comps.
Q1: hfe 57, leakage 0.08
Q2: hfe 306 (yes..), leakage 0.60
Q3: hfe 2718 ahem.. 358, leakage 0.83 (i really had to wait for this one to settle, but remember these are truly shitty transistors!)

My fave fuzz (after all ive been collecting 60es rock all my life have not i).
Built on a bakelite sheet point to point.
