I play through a HX Stomp into a QSC K12.2, much as I like playing around with the Stomp I mainly use it for a touch of compression and really small eq tweaks. What always surprises me is just how superb the basses sound plugged directly into the QSC. I spend decades looking for bass amps that reproduced the sound of the bass without adding or subtracting any colour. Now I realise I’m almost certainly an exception here but when I buy a bass, second hand or new, I don’t amplify it, I listen to it acoustically, when I like a bass and subsequently buy it, that acoustic sound is what I’m looking for when amplified, uncoloured, just (obviously) louder! The QSC is the only amplification solution that has ever given me this. I use The Stomps sims sometimes with my short scale fretless simply to get a tone near to that of an upright bass but again I find it difficult to beat the sound that I get directly plugged in. The Stomp has so many variables to tweak that I’ve barely scratched the surface but then the quality of the sounds just plugging in the basses directly is so good I’m in no hurry!
