Tried it out last week, but didn't like it with my setup so I mailed it back. Solid feeling pedal and the new plexi top is really cool. :thumbsup

Any chance of tracing this? If there's a schematic somewhere I would be very grateful if someone could PM me.

One step at a time, my dear lad... I'm afraid that there's a bit of waiting to be done, alas... :) Baba Slim sends you a beer. :hug:

Here is my guess, based on the gut pictures and description form the company:

1. Input gain stage similar to DOD250 or MXR D+ : uses a reverse log taper as a variable resistor between the inverting input of an OA stage and a capacitor to ground or reference, so that you have a "fat" tone at low gain levels yet a "focused" tone at higher gain settings

2. Body and Air are probably gyrator based band filters (at least the Body, Air might be a shelving filter). My guess here is based on the fact that they used identical W taper potties.

3. Level is probably just a regular voltage divider. Could be a more elaborate circuit, but I won't give them credit so quickly :wink:

4. The 4 position switch might be used to change center frequency or Q of the body and air filter.

2c...

It seems to be a (very nicely voiced, if I might say)active baxandall tonestack, with dry/wet blend. The voicing knob has to change the bass and treble caps.

It would be great if there was a schematic, this is a completely underrated pedal, which is kind of surprising...
