Original jazz bass pickup set made by Provision workshop in Ube City, Yamaguchi Prefecture. Resistance: Front 7.6Ω・m, Rear 8.8Ω・m Popular among JB users as a Fender vintage sound PU. The appeal lies in its extremely fast response and ability to clearly express picking nuances. I hear it's also well-regarded by sound engineers. It seems Provision doesn't sell individual parts. If you'd like to try it, please consider this.
