I received this head in a trade. Like it and have been useing it with a boss ms3 4 cable method. Keep gain on about 1 to 2 o'clock with a sd-1 available to add more. When playing with alot of hammer on, pull offs and slides across the fretboard it seems to fight me. One thing I love about the amp is the master volumes are after the loop and is easy to bypass preamp and go steaight in with the cosm metal zone built into the ms3. When I do that sustain and touch are great! Is this just the nature of the H preamp or should I do something that would improve it for my needs? Should I just get an Archon or MT15? Thanks everyone.
