Get the Most Out of Your Pickups

If you’re looking to upgrade the electronics in your Jazz Bass, the 920D Custom JB-CON-C J Jazz Bass Concentric Control Plate Upgrade utilizes only the finest pots, caps, and wiring to take your tone to the next level. A set of CTS concentric pots, ceramic capacitors, and a durable Pure Tone output jack all come pre-installed to the chrome control plate, greatly reducing the need for soldering on the user’s end. Custom builds can often leave a rat’s nest of messy wiring in your control cavity if you're not a soldering pro. Organized wiring and clean solder joints prevent tangling and other electronics failure, and wiring doesn’t get much cleaner than a build by 920D Custom — even the technicians in Sweetwater’s Guitar Gallery are impressed by the perfect portioning of 920D custom’s top-quality Gavitt wiring!

Pure Tone 1/4-inch output jack

The modern Pure Tone jack eliminates crackle and hum by upgrading the standard number of contact points between the instrument and cable from 1 to 4. This great leap forward gives players a more resilient, sturdy output jack that is much less prone to all sorts of failures. Forward-thinking creators like 920D believe that Pure Tone is the future of jacks, and we’re inclined to agree.

920D Custom signature wiring by Gavitt Wire

Gavitt Wire has collaborated with 920D on a signature cloth-covered pushback wire that yields superior balance between capacitance and resistance — in other words, better tone. This custom Gavitt wire features an inner Celanese braid that is rugged and set to hold up to repeated use.

920D Custom JB-CON-C J Jazz Bass Concentric Control Plate Upgrade Features:

  • All electronics come pre-installed to the control plate to almost completely eliminate the need for soldering
  • Includes: 1 control plate, 2 Chrome Dome concentric knobs, 1 x .033uF ceramic capacitor, 1 x .047uF ceramic capacitor, 1 Pure Tone output jack, 1 x 250k concentric CTS pot, and 1 x 500k concentric CTS pot
  • Ultra-neat wiring and clean solder joints for optimal tone and reliability

Reviews

Fender Jazz Bass Stacked Pots Control Plate
This is what every Jazz Bass owner needs.
It gives you full individual control of volume and most importantly, tone.
Fender or other similar manufacturers should always offer this as an option.
Installation is simple. Three screws and a little bit of soldering, done.
I highly recommend this for all Jazz Bass owners.
Music background: Bassist for over 50 years.
