I got this wah / boost pedal in to work with; great little pedal that can be used as a wah pedal for keyboard, bass and guitar. Great to use although the boost is LOUD! I barely touch the boost knob and it screams! Opened up it looks like this:

On the Morley site I found a little schematic which I posted here but mine does differ slight from it; redrawn schematic here

Enjoy!

Cool!
The boost could be a fun circuit to add to the DIY community's collection of booster projects.

Cool...
besdde the schematic I can see a lot of Mojo-resistors used.
Can you exchange them with metalfilm and send me the mojo-staff so that I can get rich with them using in my mojo-pedals ? :wink: :lol:

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

You can still purchase carbon comp resistors new. Ohmite and Stackpole are both producing them. There's no need to tear up old equipment to get the mojo. :lol:


Wait... I am also guilty of such things. :oops:

A big pile of mojo. Organ amps are where I find my rarest mojo parts.
