I got it used off of ebay a month ago. I KNOW it was heavily used because when I opened it up, there were alot of dust buildup in and near the fan. I demo'd a new one (not the B2RE) through a SVT-15E (1x15) at GC and it sounded warm and lively. I use an Avatar 2x12 and I thought the missing ingredient was the SVT-15E, so I got one and paired it up with the used B2R and it still sounds dull although better than the Avatar. Do I have an amp head that's nearing the end of it's life? Is it possible to for a SS amp to lose it's tone after heavy use? Does freshness really count - should I look for a born on date?
