Right now running 4cm into my Mark V 35 with a 1x12 V30 Cab. Trying to use a few scenes on one preset to switch between Mark V distortion for lead and rhythm. Channel 2 Mark IIc+. Then switch to using the poweramp of the Mark and use a Jc120 for clean. I got it working correctly. Just my midi is being a pain which I posted elsewhere. Anyhow once I get it switching correctly with a controller I like it so far. I might go for a FRFR. I just really like my Mark V.
