I'd have to agree. I love MTD's, but you have to be careful that mixing is done well.
I've played lots of basses in lots of venues. My Roscoe and Sukop both had Bartolini pre-amps and pickups (like an MTD), they were the hardest for the sound guy to mix; and the other musicians complained about my tone being hard to hear; it seemed very "round" and "lifeless", which I unfortunately had to agree with, and we were all using in-ear monitors. Meanwhile, I have consistently received compliments by many musicians and sound guys about the tone, cut-through, and presence of my Carvin SB5000 (Also while playing in a gospel band), it is my main workhorse now because of that.
Overall, something like a Sadowsky or Carvin SB5000 (or any other super jazz) will cut through a little easier than something like an MTD, from my experience.
Now I'm sure there are hundreds of guys out there who will say they get great tone and plenty of compliments about the tone of their MTD, and also rave about how well it sits in the band mix for them. But from my experience, gigging many basses at the same venues with the same musicians, the single coil J-basses have been the easiest to sit well in a live-band mix, without extensive mixing needed.
If you get an MTD, I recommend you get an amp or DI that highlights the basses natural tonal qualities and contributes to a good live mix.
