Uber metal i a good pedal.the insane mode is really nice for riffing.But no pedal or preamp can give this "feeeling" ,"headroom" a and "dynamics".
But if you play mostly no metal and just want to record r jam ,the uber metal is a good choice.But keep in mind there are other good pedals with more "feeling" like rocktron rampage or silver dragon,boss mega distortion or metal zone ,digitech black 13 ,vox bulldog(this one is a killer)...these are the pedals that i have experience ,there are other once like Krank Distortus Maximus and so ,but i have no idea how they sound in "real" situations.BUt uber metal is a good one.I played it thru a Crate gtx 30 or somethin.even on this amp was it real clear and fat !!!and it has a gate!!
