I can even make the MT-2 sound like the DS-1 with the additional help of the GE-7
Okay this is not very Metally eh?, guess my point is you can tweak any of the Boss distortion-or overdrive pedals with the help of an EQ box or something of that kind.
To create to valve warmth in your MT-2 you could use a SansAmp Bassdriver...........oh do not ask about the price of these boxes, you would just need to buy smart, you know, when a shop wants to get rid of all their guitar-gear or just rob a bank.
