A bit labour intensive yeah, I have a couple if tunes in my hiphop/dubstep band that have every note swelled...I'm not riding the volume pedal for 8mins lol. Plus the Me-50b volume function has a noticeable notch between off and on, so it's hard to be consistent.
As you might have guessed from my other thread, I'm vaguely thinking about replacing it for single pedals, but it's a great piece if kit, so we'll see
