I am looking for a durable low noise volume pedal to use in my effect loop for solos. Will that work there? I want to use it in the efx loop because I dont want to alter the gain/OD/tone/etc, I just want more volume for a solo. I have already looked at boosters like the RC, but I am considering a volume pedal to allow a little more control. Any suggestions on a good one? I would prefer one that did not color my sound much and maybe has a true bypass. What are the pros n cons of passive vs. active volume pedals?
