  • Introduction

    For the proper installation and wiring of your GAS Pickups, we strongly recommend letting a professional luthier or electrician perform this job in order for the pickups to be installed correctly and with no damage, which would harm the pickup’s functionality and warranty.


    All GAS GM Singles are delivered with cream plastic covers, proper height adjustment screws (installation on the wood), and springs (or rubber tubes).


    GAS GM Singles come with two cloth hookup wires, a black and a white one. In the case of a set, if the neck pickup is RW/RP there will be a yellow wire instead of the white one. Usually the black wires will be grounded, while the white and yellow ones will go hot. However, if you install a GAS GM Single along with pickups of other brands on the same guitar and face out-of-phase problems when operating with them, just swap the black with the white (or yellow) wires. For the desired wiring diagram of your guitar, please refer to the dozens of specialized websites with such diagrams, depending on the desired configuration.

    Pickup height or string distance

    There is a lot of conversation on this item. The fact is, there is no absolute guidance for a generic pickup height adjustment! The distance of a pickup to the strings is dependent on countless factors, such as pickup output, pickup position, string gauge, the guitar itself, the guitarist’s overall playing technique (string hitting, etc.), and the musical styles that are about to be covered. In the case of a pickup set, usually the pickup height is adjusted so all pickups show a similar output level, but this is not a rule. Our recommendation: The desired pickup height adjustment is a procedure that may last longer than you think; just start with a generic distance of 2mm on the e strings and repeat the procedure (adjust, play, listen, re-adjust) until you are satisfied. Don’t forget to adjust in small steps (e.g., one full turn of the height adjustment screw each time) in order to easily come back one step if you are not happy with the new situation. And, trust us, if you just repeat the whole thing a couple of weeks later, you will probably find yourself re-adjusting the height again. It is something that each musician should go through by himself.


    GAS GM Singles are direct replacements for Fender® Jazzmaster® guitars and similar models. The pickup’s dimensions (including a pickup cover) are as follows (sizes in mm):

    • The differences are the overall higher output of the 64 set and the designed louder bridge pickup in the 64 set, which results in a meatier tone.

    • Originally, the Jazzmaster® had 1 MOhm pots in the main circuit and 100 kOhm in the jazz circuit. The 64 set would run perfectly in this configuration. Referring to the 62 set, if it sounds too trebly, 500 kOhm pots might be a better solution.
