Re: any speaker recomendations?
I've had a lot of experience with these and devilles, the best options i've found are
g12h30/eminence wizard
Weber California
Eminence Cannabis Rex
The h30/wyzzzrrrdd is gonna be your most rockin option. Cleans are still great and it'll take out some of the weird mids. Go h30 if you want speaker distortion, wizard if you don't (I'd go wizard in this amp but it's your call)
Cali (with a paper dome) is gonna be your cleanest option. It sounds good with gain too but maybe has slightly less clarity under gain than the h30, which I kind of like. EQ on these is really, really close to totally flat, with plenty of range on either end
CRex is gonna be the "warm" option, smoky is a good way to describe it, but still relatively clear sounding. This one has the most mids, but they're more orange-ish low mids than marshall-ish middy mid mids.
For your punky screamo kinda indie needs... I'd probably go with the wiz
