This is not really a troubleshooting thread but I've noticed some curious behavior with my recent MBP ManOWar (Maxon AD-900) delay build.
Actually, I'm not even sure it's an impedance issue but I suspect it is.
So here's the behavior:
If I run it in my normal pedal chain at the end of the chain with nothing else turned on, it works as expected. Plenty of gain, I can set the "Mix" knob pretty high and get at least unity on the repeats as my dry signal. BUT, turn on an overdrive of any kind and it sends it into wild self oscillation and I have to turn the mix down to almost complete CCW.
My use case is running dual analog delays in series, one into the other with different delay times. I have a buffered loop where my delays and reverb live.
If I put the MOW in the loop BEFORE my TourBus, it behaves pretty well but for some reason I lose a LOT of mix. In other words, I have to max the mix knob to even hear the repeats. If I put it AFTER the Tourbus any delay signal from the Tourbus sends it into the same crazy self oscillation as with an overdrive.
I've tried running it outside of the buffered loop but at the end of my chain (before the loop) but I can't run any overdrives without it going into that gonzo self oscillation.
So right now I have it IN the loop and BEFORE the Tourbus. It's working and sounds great for my needs, but I have the MIX knob maxed to make it work as a dual delay.
I've tried re-calibrating following the instructions for the trimmers a couple of times and it does not seem to affect this behavior. I'm not sure if I should just chalk this up to idiosyncrasies of this pedal and roll with it. But I am curious as to what's going on and why in standalone mode it behaves like it should but clearly doesn't like to play well with most other pedals.
My other BBD Delay (The AquaBaby - Boss DM2) doesn't do this but I like the sound of the ManOWar better.
TIA!!
