Maestro FZ-1a Fuzz Tone

dates about 1966-67

Well.. At last i can say it: my clone (see back pages/older posts) sounds GREAT. Against this original (2N2614 transistors), with little or no attack pot excursion, aka max it or it wont fuzz, my clone is a pot full of sweet spots. Maxed, it is plain evil. Compressed.

Comparison, original vs my clone:


Still, the original has got so much mojo.. Magic. I will not mod it to bias the transistors better. As the Poets said, THAT’S THE WAY IT’S GOT TO BE.


Maestro FZ-1 Fuzz Tone

The first fuzz box.. The Satisfaction horns sound, the star of so many fuzztonic records. I had to make myself the perfect clone! Yes i built a couple of these before, but i wanted to build it properly.. This is what i came up with:

Finding 2N270 transistors to buy was HELL. Impossible, hard to find, someone who sells them. Rca’s here in Europe, NONE. Forget it. Until…

I did find them! A small stash of them actually! And i didnt have to sell my body to get them. Not RCA’s, but NOS 2N270: leaky, gainy, nasty 2N270s!
Next, i set up this testing board with a nice ZIF socket!

First good set-listen:


Q1 hfe 79 lkge 0.12mA

Q2 hfe 168 lkge 0.53 mA

Q3 hfe 131 lkge 0.70 mA

I tried inverting Q3 and Q2 but the distortion was oscillating..
