I wouldn't do anything out of the ordinary. Just use what you would normally use for a humbucker (pots and caps) and see how it sounds. Don't automatically assume that it will sound trebly or not warm enough just because it's from a guitar.
I owned a Rick 4004 and 650 (guitar) at the same time. Pickups are identical. Sound was completely different with the different tuning, scale length and strings, i.e. the guitar didn't sound like it had a bass pickup on it, and vice versa.
