Nau Engineering has long been regarded by the Rochester musical community as the premiere shop for servicing, repairing or restoring your bass or guitar amp. Virtually any guitar or bass amp can be repaired, restored, or even modified (the exception would be the very cheap Chinese made surface mount circuit board style amps). Nau Engineering also provides guitar and bass instrument repair, especially electronic repairs to guitars and basses, pickup swaps, etc. Send a message though the contact page or call (585) 594-8129 to inquire about a repair.
