I have a Fishman Pro EQ Platinum Bass pre-amp and it's working fine for more than five years. But some parts are getting old, I have lost some screws, a button, and one of the clips that hold the battery box in place is broken. I would like to get some of these parts to refurbish my pre-amp. I sent an email to Fishman, but they did not reply. Anyone knows where can I get these parts?
