Im a relatively new taper, I havent taped any super loud bands so I always left the bass filter on the medium setting and things have been great. But I will be taping The Mars Volta soon, and I was wondering if I will need to increase or decrease the rolloff for their shows, as they are a LOUD band. Also I actually dont have the indicators for which direction is increase/decrease so if I do have to use it could you perhaps tell me which direction is to up/down.
(hope that last part made sense)
