Welcome and congrats! Never had any problems with my PC1 squealing. Maybe one of the other members can help out. Let's see a pic of your chlorine anyways!

Sounds like someone (previous owner perhaps) has been playing with the trim pots on the sustianer board.
There are two of them and you needs a small plastic phillips head screw driver to adjust them.
There's a process to resetting the board, but you need to be comfortable with opening the guitar up and adjusting it.

You basically mark their current position with a fine tip sharpie for reference and then center both trim pots and then adjust from there while the guitar is plugged in.
Flip between normal and harmonic sustain modes while adjusting until the squealing is gone.

Here she is...I'll do some glamour shots later




The other thing the previous owner did was swap the Super 3 for a Tremonti pickup...I'll probably put it back to stock, not that I hate the Tremonti, but it's a standard 50mm spacing and the pole alignment is a little off, so I'm probably not getting everything I can get out of it anyways.

Thanks for the tip Rick, I'll open it up and take a look this weekend, hopefully I can dial it in because I really love the effect!

Welcome. Nice guitar! Doesn't really matter if the pole piece alignment of the pickup to the strings is off, you probably won't hear any difference anyway.

sweet finish and the gold hardware looks epic

Nice looking chlorine. That's one of the better looking new ones test I've seen. Congrats.

Nice top on that one
