Asking the experts on here. I will be buying a used practice amp. Looking for something that offers "clarity" on clean tones for good practice feedback and some gain/tonal settings to keep it interesting. Volume is not important. Any good bang for the buck combos you'd recommend? I've been considering the Behringer GM108, Fender Champion 20 and Fender Mustang 1 v2 but have really no idea as the selection is overwhelming.
