This is my first time using this site but had to find someone who could help me price out my Ampeg B-12-XTC Portaflex amp (the 4 by 12" version of the B-12-xt). Im guessing the relative rarity of the amp is what is making the value so hard to determine but does anyone have a ballpark figure for it. Its in excellent, not mint, condition but sounds perfect with no noise or hum and very few dings on the back. All original. I know they were only produced for one year so but if anyone has any info at all that would be amazing!
