I probably said enough about the Crowther Hotcake (and New Zealanders) in the previous post - so I'll stop now. Short story - it’s straight op amp clipping with some filtering.
Although I should say that this has an unusual bypass system - it's not true bypass, note the switching. I’ve included a modded layout for standard true bypass switching.
CROWTHER 1977 HOTCAKE VERO LAYOUT
I built this and there's a wiring error in the diagram. As shown, the drive pot works in reverse. The outer wire on the Drive pot (gray D) should be on the other side (left side when viewed from behind) to work as expected.
ReplyDeleteOtherwise this pedal sounds really good, except the bypass system makes it unusable. It has to be at max volume for unity gain in bypass. Which means every time you turn the pedal on, you need to duck the volume knob, or else blast the crap out of your amp.
For most people, probably best to jumper the bypass pads, and wire it in millennium true bypass.
Thanks - I’ll check it out and update the layout
