All my guitars sound great through this, recording using a mic is excellent, even recording straight off the headphone output is better than using effects pedals as preamps. As predominantly a bass player, I used to use my treble guitars through my bass head and a 2 by 12 cab thinking they sound pretty good, but now I realise what I've been missing. I've spent more money on pedals with the effects this combo has ,than I paid for the Boss Katana. Electro acoustic guitars sound pretty good too.
