the zvex super hard on.
it is the best booster ever. Seriously.
what amp are you using and how overdriven is it?
Then they are nothing like a SHO, sorry. The SHO is very coloured. It's a thick, loud, syrupy, crackling beast of a boost that does not like every amp/guitar combo on either side of it, but when you do get it right it's downright monstrous!the SHO is great. I played a few SHO-based boosters and I have to say it really sounds like "more of your own amp", more so than any overdrive pedal I've tried.
It can dial in some crazy boost but it never sounds "colored".
actually it´s a Frankestein i made hooking the Roland Cube 30 to a 2x12 cabinet loaded with two Celestion G-12 S 20W and i`m really digging the way it sounds through this speakers.
for the rhythm sound i use the Rectifier model...so it´s pretty saturated.
with no loop you arent going to be able to do much. if you have that much gain, almost anything that you put in front of it is only going to mush the sound up with out giving you any extra volume
You're using a modelled Rectifier sound that is already saturated. Whatever you put in front of it is just going to make it sound more saturated and probably not in a good way. None of the suggestions made before Jeremy's questions will be much use to you.
Are you looking for more gain or a volume boost ? I don't think the Cube has a loop which will be a problem if you want more volume. If you get feedback using an O/D pedal I think you have probably already pushed the amp to the limits of what it can do.
even an EQ?
