So I bought a used Heat +FX on reverb, and it arrived in a box that clearly displayed water damage. So of course I quickly opened it up and tested it out - it worked perfectly. I have owned an OG Heat before so I knew what to expect. I recorded a full track through it with no issues whatsoever.
A few days later, I decided to sell it on reverb because I needed to majorly downsize my setup for a new living situation. The person who ends up buying it messages me immediately saying they were getting crackling out of the right output on Clean Boost and Saturation. They troubleshoot and get nowhere, so they return it to me for a refund.
I have it now and there is clearly something wrong with the right outputs. No matter what mode you are in you can barely hear anything on the right side, and occasionally you get severe crackling/pops. Everything else seems to be working. I’m probably out of luck with reverb to try and return it to the original owner. So my question is:
How hard would it be to try and fix this thing? Does anybody have any advice for me?
