yup, it's a not a great amp for bass. (maybe at low volumes, but i didn't try it for fear of killing the older than me cones) but jeez! yeah, this is a BASS forum, but indulge me. My GP is an amp freak and in addition to other amps of various types, modern and vintage, he has quite a collection of vintage fender blackface amps - (which sound head and shoulders much better than re-issues). However, he recently scored a vintage '59 tweed bassman and all i can say is WOW! What a freakin' tone monster of a guitar amp. Light as a feather too. It easily replaced his 100 watt marshall head and 4x12 cab and is sooooooo mush easier to transport. Even the blackface super, vibroverb, deluxe, pro, twin, and vibroluxe sound pale in comparison. I think i'm in love.
