Hello everyone Looking for a recommendation on a good amp repair place within a reasonable drive of Sioux Falls, SD (i.e., no farther than the Twin Cities or Omaha). Situation is I have an early 90s (Transient Attack) Hartke 3500 head that has had the onboard XLR short-out 8 or 9 times in the last several years. Nobody around here seems to be able to make a fix that sticks. I need it done right this time. Would prefer to deliver and pick-up myself vs. shipping, hence the distance considerations. Feel free to either respond on this board or via PM. Thanks in advance.
