Has anyone ever had issues with a Hartke Hydrive HD112 cabinet as far as slight distortion on lower Bass notes (like Open low E and A)? Just purchased a Used one that is in Excellent Looking Condition (Looks like New) but when compared to my Original HD112 (had around 3 yrs now and still sounds Clear and Great...AND I LOVE IT!!!) it seems to have a slight Raspy Buzz as the note is Decaying? Has anyone had to DEAL with Guitar Center or Hartke / Sansom as far as Repairs or Parts for a Cabinet they want to FIX and KEEP (vs) RETURNING for REIMBURSEMENT? (as I only have about 30 days left to decide?)
