Get the Most Out of Your Pickups

If you’re looking to upgrade the electronics in your 4-string, the 920D Custom JB-CON-CH-BK Dual Pickup 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-CH-BK Dual Pickup 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/Black 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

The Finishing Touch

My parts Fender Jazz has been a long journey, starting out as a mid nineties MIM Jazz bass. Fast forward, the only original part is the body. I recently replaced the Bartolini pickups with DiMarzio 60's pickups, ( they are amazing). I had the Audere JZ drop in active preamp, which again sounds great, but I really wanted to hear these 60's pickups the way they should be. I've never used the concentric preamp configuration before, and I thought this would be a great way to go! The 920D Custom seemed to be the right choice, and I am here to say, YES! The 920D Custom uses all quality parts and the wiring and assembly is top rate. My soldering skills are ok at best, but I found the 920D Custom directions along with the DiMarzio schematics no problem, (along with a little YouTube soldering brush up help). Right out of the gate, I was blown away by the sound! The 920D Custom really lets the DiMarzio 60's shine. I love the ability to adjust the tone and volume of the in dividual pickups! I used the bass through an entire rehearsal with my blues band and our guitarist kept commenting on how great the bass sounded. I find I don't want to stop playing this bass now, it's become one of my favorites. My mid nineties MIM Jazz's journey to greatness has finally reached its destination.

Great option for what I was looking for

I put this on an American Original 60's Jazz Bass. Immediately a huge difference in the tone options as I was now able to adjust each pickup's tone.
