Hello,
Rebooted MP-1 user here! I had one back in 1990 and I loved it, but traded it later to "simplify" with a Marshall rig. I have just obtained an old MP-1 (the one with the open hole to the switch) and I am really digging what I hear. I also picked up an old Roland GP-8 and the ADA B200S as well. I think, including some trades, I paid around 450.00 total for all of that...which is crazy! Not liking the B200S so far as my pickups don't respond to the SS like they do to a tube amp, so I think I am having a friend build a small, low watt, tube slave amp for the MP-1. Anyway...just wanted to say hello and I'm sure I'll be asking a million questions and hopefully I can be of help to someone too!
