I just put a Tony Franklin fretless neck on an 80's Tokai P Bass body. Had to slim the heel to fit the pocket, all well and good.
What I had not figured on was the bridge height relative to the fretboard. I've had to max the height adjustment screws which causes the saddle intonation screws to be sticking up at an angle almost to string height. This gets in the way when I mute back there with my hand.
The fingerboard height relative to the body looks right, you can just see the side dots above the body at the end of the neck. I don't think lowering the pocket is the answer due to this, I would sooner leave it as is. That leaves me with only one other idea, and that replacing the vintage Hipshot bridge with something that sits taller, like with a thicker plate on the bottom (Gotoh 201?). What would you do?
Take a look...
