Anyone Well Versed In Maestro Boomerang History?

[Paul Marossy]

I know everyone isn't rushing out to build one of these because it's not a Cylde McCoy clone, but I will record this here for posterity...

I just realized that the schematic that I built my original Boomerang clone from had a mistake on it - the feedback resistor on the second transistor is labeled as a 620K, but I have verified from looking at a real Boomerang wah pedal that it is actually an 820K resistor. Using a 620K resistor here increases the noise floor quite a bit. With the 820K resistor and some 2N3904 transistors, it sounds just about exactly the same as my 1972 Maestro Boomerang. It took a while, but I finally got it to sound like it's supposed to, and it solves the mystery of why my first build was so noisy, comparatively speaking.
