Finally took my Boss SD-1 back out last night. Hot dang!! Remembering that a Boss SD-1 and a Marshall were meant to be. Makes my HSS Strat sound phenomenal. Tight, crunchy, and very fluid-y all in one. Notes are very articulate, ring and sing. Copping some HUGE Lifeson tones without even trying ( TC Nova Repeater and Boss CE-20). My MXR 10 Band might have to sit this one out. Edit: 10 Band EQ now sits in the loop where it now adds back in the Bass from clean boosting the front with the SD-1. Tight, thick, creamy sustain. Y'all have to try it sometime! Boss SD-1 fans around here??
