I picked up a 3leaf GR2 fairly recently, but I've been having problems getting it to 'trigger' correctly.
Basically when I play 'normally', even with sensitivity high, I struggle to get it to make any noticeable difference to the sound.
If I run a fuzz beforehand then it's fine, quacky as anything. I've tried using the fuzz in and out of the effects loop with no discernible changes. The signal chain is bass>preamp pedal>octaver>fuzz>GR2.
I've adjusted the trimpot inside and it was better, but still not full on squelch.
It sort of seems that the signal coming into it isn't hot enough, but that isn't right as I'm using an active bass, and there's also a preamp pedal at the beginning of the signal chain. It's the same whether in the effects chain or plugged directly into the pedal.
It's really odd because the setup has been fine with other filter pedals I've used; I have an old Boss FT2 which works fine (albeit not as well sonically) as the GR2 should, and the SourceAudio filter I had before also worked with the same setup.
Does anyone have any ideas?
