Ive been gassin' lately for all tubes.... I currently have a DB750, and was wondering what the tonal differences are between the three. I currently use a gs410 (4ohm), but am looking into a NV610. I play all kinds of tunes from pop, funk,rock,country ect, just no metal or jazz, and I don't do the uber bright and scooped slap stuff, just some 70's stlye slapin' if I do. I'm looking for a great "creamy" CLEAN sound. I'm not into distortion, or overdriven crunch, just a nice clean but thick tone. Are either of these all tube amps going to do this for me, or am I better off keeping the DB750?
