Title: Easy vibe and Depth knob
Post by: Plexi on October 31, 2017, 09:22:01 PM
Today I receive an Easy Vibe, made time ago by an actual knowed crafter.
It works in strange way, sounds good, but the only concern is that it only made the effect when the Depth pot is more than 2 o 3 o'clock.

The tester measure that pot ~60k, I'll have to disarm it and check that pot value

I think that maybe a A50K pot can do a better work?

A log pot will make it worse.
The easiest solution is probably to put a resistor between lug 1 and ground [edit - VB , the point where the depth pot lug 1 was originally connected]. Sounds like you need something like a 33k.

Thanks... I'll try some lower value there.


I was reading about "Mark Hammer's anti-ticking" and "Piotr Zapart's LFO" mods.. bud didn't found any schematic yet.

Maybe Mark can add some light here  ;D

I would like to add:
- 100uF instead 10uF over C8
- TL072 instead TL062
