My Tweaker had been unused for over a year (I have a Yamaha Thr5). Figuring it will cost over $100 to fix the amp I was considering the New Boss Amps. Also trading in my Tweaker Cab and Carbom Copy Delay in the transaction (hoping for $150 in credit). I play only at home and I do not need a 15 watt amp. Not sure what to do.
