Noticing that I can get a lot of extra noise when using a active buffer pedal, probably because of some weird ground loops and DAW interference because of the desire to record a Direct Track for later, reamping. What are some ULTRA-QUIET buffer pedals to check out? I'm basically looking for something Passive that might possibly give me 'less noise grief'. Anything besides the Radial Stuff? I have a Bigshot, it's great but I feel there could be better. Maybe battery powered? cheers!
