I finally found a shop in NZ that has a Mesa Basis M-2000 (no footswitch tho, which is a bit disappointing). Flicking off my GK1001 rig for the 400+ a year ago was a no-brainer, but I've heard so many mixed opinions about the tone/playability of the M2000, and it's pretty unanimous how great the 400+ is so I'm at a bit of a loss. To make the decision harder, the M2000 is at the other end of the country, so I dont have the opportunity to play it first. But it has that juicey high-gain tube channel which I'm dying for (use distorted bass in half of our songs), and I'm not that fussed about the tone of my 400+ - I run a Sansamp RBI in front of everything anyway (im addicted to the sansamp sound). So any recommendations? The M2000 is a great amp, but will I regret losing the 400+? chur!
