Has anyone on here converted the tone pot for the bridge pickup into a bass cut one where the amount of cut can be dialed in? If so, could you guide me on how to do this? Thanks in advance.

I think Bob Young did such a mod and has discussed how to do so a few years ago.

Reverend Guitars has a bass cut tone pot on most of their guitars, they could be a source of information, too.

I did it with a 1Meg pot and a .0047 cap.
Remove the tone pot: Unsolder the cap at the switch being careful not to remove the treble pup hot lead. You may need to lightly re-solder the hot lead
with a little fresh solder. Unsolder the ground(s). Remove the tone pot. Install the 1meg pot.
Unsolder the treble pup hot lead from the volume pot (this lead goes to the switch).
Attach(but do not solder yet) the cap to the center eyelet and one of the outer eyelets.
Make sure that the outer eyelet you choose is in the direction you want the "no-cut" to be.
For full clockwise "no-cut" this would be the right eyelet when you look at the pot as it is mounted to the guard, and the eyelets are along the top and not bottom.
Attach the treble lead from the switch to the center eyelet, attach a lead from the same outer eyelet as the other end of the cap.
Solder the leads in place. Then trim any excess wire.
Attach the loose lead to the eyelet of the volume pot that you unsoldered in the beginning.
Solder the ground wire(s) to the back of the new pot. You may need to sand a little spot on the pot to remove any finish that would prevent a proper connection or solder joint.
Please note that I'm doing this from memory; if I've missed anything chime in.....
