Last year, when I was playing just rock and soul music, I sold my 1980s Polytone Mini Teeney Brute amplifier (100 watts, 12" speaker, good condition) to a jazz guitar player who fell in love with it. I used the proceeds to buy a Fender Rumble 350 combo amp. Now I'm in a jazz group that is gigging 2-3 times a week and I'm using my 1966 Ampeg B-18N as my main amp. I love the tone and don't mind hauling it around, but I miss my Polytone. A Stagg Electric Double Bass has recently replaced the Bill Nash '57 P-Bass that was my main jazz gig bass. The guy I sold the Polytone to is willing to sell it back to me for what he bought it for (he's moved on to drums). Should I buy back the Polytone and use it for jazz? Keep using the Ampeg B18? Or start using the Fender Rumble 350? I love the B18's sound, I like the Fender's reliability, but the Polytone would be portable, plus it has a nice clean tone. What do you think?
