I'm thinking of recapping my JP-4...

I've already done the power supply, and solved the dodgy 'track crack' issue in the control boards. I also desoldered every fader, cleaned it out, re-tensioned it, rebuilt it and measured it again, before resoldering. Took ages, but thoroughly worth it.

What brand of caps did you use, if you don't mind me asking?

I used a mix of Nichicon and Panasonic caps (FWIW most of the original caps in the JP-4 are Panasonic/Matsushita brand). For mine I splurged a bit and mostly used audio-grade caps, but regular general purpose caps work just fine.
Had: DX7, AX-60, SR-16, Yamaha TQ5, 01/WFD, Juno-106, MG-1, JX-03
Want: OB-6, Prophet 6, Jupiter-6
