I'm finding that sometimes my powered toaster doesn't give me the hairy zizzle womp through a traditional speaker cab like my amps do for high gain.
So I've been adding a recti shaper in either the X or mod slot and it seems to be doing the trick!
I only set the gain in the recti shaper at about 0.3 - 0.9 and the volume no more than a +1 if at all. Hope this helps and cheers to those that already do!
