Moog Music Forum

I have a MF102 I've been using mainly with my guitar rig for a little under a year.. I've been totally happy with it, but recently it started doing something weird. If I play a short, percussive sound (like pluck a muted string on a guitar, or snap my fingers through a mic) - I can hear the carrier oscillator bleeding through and ringing out for several seconds after the input signal decays.

In other words - if I play a dry finger snap into the input, I hear a metallic pop (like you would expect), followed by 1-2 full seconds of a sustaining ringing sound relative to the Frequency knob setting.

I have always used the supplied power adapter and it's been on my board since day one.. has anyone else experienced this? It's frustrating, and I'm not able to even use the pedal with my guitar setup like this...

There will always be some bleed-through, but it sounds like something is wrong with the squelch circuit. I'd contact Moog.

I contaced tech support last night and got a response this morning. There is a trim pot inside the pedal to adjust the carrier squelch. After a little tweaking, the bleed-through is virtually unnoticeable in the studio, and certainly won't be heard in the mix with my guitar setup. Everything is back to normal now - great support experience, and I didn't even have to send my pedal in.

Does anyone know what the other MF-102 trimpot is for ?
