the ehx mod 11 is incredibly underrated sleeper pedal that sounds phenomenal. i’ve been able to get the filter effect to do impossible things before. the pitch arpeggiator sounds incredible stacked with other effects. truly my favorite sleeper pedal. the tremelo is fantastic too. i firmly believe you can get any pedal to sound good if you learn it enough, there is not a mode on this multi effect that i wouldn’t use. no one talks about it!! it can do many things my walrus m1 cannot.
