Purchased the Little Mark II from a local GC on Friday. I'm possibly still buying a used iAMP, but wanted to try out the LMK after all I'd read.
Anyway, I played the LMK the day after it was put out on the floor in the store and was impressed, but I wasn't sold on it just yet since the environment is never the best for making the ultimate decision. Also, there was one other problem: The tip of a cable had been broken off the day it was put on the floor, and although there was a signal and the amp worked fine, the cable couldn't lock in all the way with the tip of the other cable lodged in the input jack.
I waited a day to ponder and went back on Friday with my plan. I asked for a new one to start and was told it was the only one they had--wasn't sure I believed it, but I expected that answer. I told the salesperson that I'd take the one off the floor, but proceeded to explain about the broken cable tip.
Well, after talking with a manager over the matter, I wound up walking out of the store with the amp for a decent amount under $600 and some other goodies tossed in. I figured that the warranty would allow me to return it if I had any problems getting the tip out of the amp--which took just a little time and non-shaky hands to make happen.
The amp is killing through my two Aggie 112s so far, but two amps won't hurt, which is why I mentioned that I may buy another amp. It's not that the LMK isn't working out, it's just for the sake of curing some G.A.S.
The amp has more breadth available than I expected, and the sound of the bass really does shine through from what I'm hearing. I will get a really good idea next week at practice with the full band, but for now, there seems to be plenty of power for medium gigs--as everyone has mentioned who's played through it, and the tones are impressive for the size and price.
