Still got 2 MTS in my amp arsenal. The RM100 was great for getting different tones, and the RM50 combo was convenient for band practice and jams without lugging a big rig.
they're great for what they are: being able to get a lot of different tones with the modules.
I got some good modded modules but in the end, my 5153 blows all the MTS out of the water. That's why i'm going to put them up for sale.
