Jazz® Bass Concentric Control Plate Upgrade

Our JB-CON-C Upgraded 62 Dual Pickup Bass Control Plate with Concentric Knobs is not only a mouthful of a name - but is also a major upgrade from stock plates. Our pre-wired, drop-in ready plate is built with premium components and will drastically clean up your tone. Each pickup has a separate volume and tone control. If you're needing to improve your tonal options on your bass, look no further than this control plate.

Hand-Built In the u.s.a

All 920D Custom creations are hand-built by experienced technicians at our shop in Greenbrier, Arkansas. We treat your new gear like it's going into one of our own guitars. Every millimeter of wire is cut precisely, every solder joint is perfectly smooth and symmetrical, and every bend is purposeful and direct. We hold everything to a tremendous level of quality because we know the smallest details matter and we take great pride in our work.

Immaculate Wiring

All 920D Custom products are highlighted with our signature orange wire. Gavitt Wire, a leading producer of premium guitar wire, has agreed to custom manufacture our signature cloth covered pushback wire, and we believe it is the perfect choice for hotrodding your guitar. The wire is built with an outer waxed cotton layer and an inner Celanese braid that provides impressive ruggedness while still maintaining a 22 gauge thickness. Limiting the amount of wire on each build compliments your choice of pickups by creating the perfect balance between capacitance and resistance.

Get Your Guitar Stadium Ready

Everything we build is designed to allow you to shape your sound exactly the way you want it.

From a single component to a fully functioning Loaded Pickguard, we help guitarists break past the limits imposed by cheaply made stock equipment.
