I haven't used the MXR, but I use a Boss 7 band in the loop of mine, and it's crazy how much more flexible it makes the amp. Solo boost, mid scoop, mid boost, it really adds flexibility.OP, I've already responded with how awesome the SD-1 is with a Marshall but forgot to mention that with the addition of an MXR 10 Band EQ in the loop, game is over. One could save themselves years of tone searching and LOTS of money. Fantastic tools to have in every rig IMHO.
