Hey Pauly
I've been using an Einstein combo for 2 years nearly now in a busy cover band (open back G12-K100 model).
Its an awesome amp. Not had the footswitch mod done as I don't need to. Spend a lot of the set on Ch1 Mode 2 Gain at around 3 o'clock. Cleans up great with guitar volume. Its like a Marshall as it should be. Made by Diezel!!!!
Heavier stuff mode 3 and gain back to noon or 1 o'clock, its a slamming sound. Just massive. Mega does its name justice.
If I need clean tone then mode 1 gain as Mode 3. Its no issue to just get to the amp and flick a switch and turn 1 knob between songs. Don't forget switchable Master 2 as well!!!
EQ can remain the same on all 3 modes. Though everything is normally around the noon mark, with a slight Bass boost if using the GL-56 on Ch 1.
Ch2 of course for leads and if required massive riffs. I stopped using any OD or boost pedals when I got Einstein. Just pointless.
So far its been pretty reliable. had one issue that was quickly solved. Also blew a speaker, oops. Just recently tried JJ KT-77's in it but that didn't work out too well. See separate thread.
Gonna keep using Ruby EL34 BHT for now.
I have a CAE 1 x 12 cab with Eminence Governor in it (closed back) that I use for bigger shows and the combination of the 2 cabs is unsettling for the rest of the band..... You could use a 2 or 4 x 12 or what have you as well if required.
Never been happier with an amp or tone experience bud.
ROCK on!!!
