'Volume-ToneStyler-Volume-ToneStyler'. Installation instructions and diagram for Rickenbacker's 300 Series, 600 Series, 4001, and 4003 models - 250 kB For basses with two pickups, pickup toggle switch, and four knobs (RIC 4003 style). Retains dual volumes, replaces one (or two) tone pot(s) with one (or two) ToneStyler(s).
When upgrading with only one ToneStyler, connect it to the bridge pickup, where it is essential; leave the other tone pot wired, as-is. Both controls will work together in the "both pickups" center toggle position.
Don't try to solder only one ToneStyler to the output jack as a "master".... this doesn't work.
