JJ would NEVER sell anything just to sell it. Bring it back, have them retune the amp, whatever they need to do. Go there on a weekday so you talk to JJ (the owner) instead of Dean who works their counter Saturdays. Trust me, they wouldnt ever have purposely done that. Of all shops Ive ever been to, including Tampa, they bend over backwards the most for you. Dean, who builds their boxes, stayed til midnight on a friday night and came in at 6 am on the following saturday just to get my friends box done quickly.
