Hey folks,

Any of y'all might know anything about this rare bird here? My search-fu pulls up next to nothing. A few pics on DiscoFreq is about it...

Ventura Wah Wah Model # P-CB-BX

Components all jibe with the Thomas Organ Cry Baby values. It even uses the same layout.
MPS3710 Transistors
100k CTS pot w/ crank arm situation...

Big-ass axial inductor like in the old Guild Fuzz Wahs. Reads 51R. I can't measure the inductance.

Not a bad sounding unit... The pot has a bland, pretty linear sweep, with little quack.

Inductor with "51R" marking is 51uH inductor. Strange value in wah-wah pedal?!

What's that serial number? 1150?

I'd like to add it to FXDB as well (hope that's ok? :)) and the serial number is interesting because the picture of #1072 has a TDK Inductor

The gut shots are good enough, I only can't read the serial number on the bottom plate :)
