I had the pleasure of playing a M-Pulse today while my buddy was making some guitar deals at a shop a few hours away from where we live. Man, that thing was smokin'. I just bought a poweramp that I'm really liking.....and since I don't have $1400 to drop on the amp(not use of used prices. So Im wondering if there are any preamps available that have a nice tubey grit and great clean tone together. I'm not looking for something that sounds exactly like the M-Pulse. I only played it for about half an hour. I'm just looking for something that would be considered similar. I'd get the M-Pulse if I could afford it.....man, that was some sweet tone..
