I've got a rather strange problem with my Microbrute. It worked fine when I got it, but after playing around with it for a while and routing the LFO to the metalizer, the triangle wave seems to have been permanently altered. Now, when I set a very basic patch with just the triangle wave, no metalizer, filter wide open, no resonance, no brute factor, no LFO amount, VCA set to gate, no envelope amount, nothing patched in the mod matrix, it still sounds like the metalizer is turned up a bit. It doesn't change if I shut it down, unplug it and start it up again.
Also, there's a lot of noise, especially on higher notes, that isn't there if I use the square or sawtooth.
Is this a known problem? Is there some way to fix it, or do I have to return it to get a new one?
