FWIW, my personal opinion is that there are tradeoffs with the 3TM. I think the 3TM excels at high-gain lead tones. It also has a very good, sparkly solid-state clean and a very nice built-in chorus. Where I feel the 3TM falls down is all of the tones in-between. I've found it impossible, for example, to get a good on-the-edge-of-breakup rhythm tone - all attempts end up sounding harsh and brittle. The Clean Tube setting becomes next to useless, and it does not respond well at all to rolling down the volume knob of your guitar, if you like to use that approach for managing your tone.
My guess is that Richard would recommend the MP-2 instead
as it has more gain available than the MP-1 and has more useable tones than the 3TM, and I'd say he would be correct. Or, consider the 3TM if you have some other way of getting your in-between crunch tones. Again, all just my opinion!
