Guidance For ToneBender MKII

[bobbythegoose]

Hi guys,

It's my first time trying to build a tonebender mkii. Can someone guide me with these results from the transistors i tested? WHat should i use them for the build q1,q2,q3

Check out @PedalBuilder's mkii build report. His builds are always incredible and well researched

Thread 'Tone Bender Mk. II Clone'

Jun 18, 2024

What to say? It's a Tone Bender Mk. II with a few slight modifications. Sonically, it's unmistakeably a Tone Bender Mk. II. I tuned it to have a little more gating and less cleanup. It does the Zeppelin thing in spades—whenever I turn it on, I invariably find myself wanting to start playing Dazed and Confused.

I used some NOS Siemens AC153Y transistors for this build. The transistor measurements are:

Q1: hFE 82, leakage 226 µA
Q2: hFE 84, leakage 354 µA
Q3: hFE 109, leakage 330 µA
Measured on a Peak DCA55 at 73ºF

The collector voltages are:
Q1: -7.76v
Q2: -0.11v
Q3: -8.34v
VCC...
