I have a vintage Polytone Bass amp (mid-late vintage70s), in pretty amazing condition for an amp that age. I can provide more specs but for now it's 180 watts, with one 15' and two 8". These are rare and I'm pretty sure it's all original, with an excellent original cover and casters This is transistor, among the earlier good ones, about 55 lbs. Everything works as it should. Speakers sound. Cosmetically 9/10. Two issues: Cord 3-prong upgrade was spliced into cord and one volume pot cracked so knob sits crooked but secure. Otherwise, this is in great shape all around Hard to find info on these, but they seem to be well regarded. Very solid as a bass amp and, I've recently discovered, quite nice as a guitar amp (two channels, four inputs). Here's an old TB thread that sings its praises. (Mine is same era but has the extra two 8s). THere are other threads out there. http://www.talkbass.com/forum/f127/fs-70s-polytone-101-bass-combo-$350-606912/ More photos coming Probably looking for $350. Local pickup only. ONly trade would be a light 115 cabinet. I'd add cash for the right Bergantino or Markbass (especially the NY115).
