Well...I think the time has possibly come for me to part with my trusty M2000. I am tired of trying to find a "perfect" tone outta this puppie. It is a wonderful amp with many options but I am starting to wonder if it is just not better suited to a thumb-style or pick player. I just can't get that deep throated tone that I used to have with my 400+ out of it (duh.) I would love to hear folks opinions on the new M-Pulse line? Mesa has told me that they are defintely voiced to be "deeper" than the M2000 but I have also seen a few TB'ers post that they found it "harsh" sounding. Frankly, I am a little very skeptical of this...? What are the main differences in overall tone between an M-Pulse and the M2000? I really love the frequecny-specific compressor on the M2000; I will hate to lose that. I only use the tube side on mine and EQ it very minimally. An amp should have a good basic tone to start with w/o a whole bunch of knob twiddeling. I unfortunetly just haven't found that with my M2000. Are the M-Pulse's "similar" in tone to any others? like...what other rigs could you compare them too? SVT grind meets GK clarity..etc, etc? Any experiances you might share, even with your Walk-a-bout's, would be most helpful. Thanks!!
