Product Format Clarification

This product includes digital design files only — no physical PCB is shipped.

With these files, you can order PCBs directly from a manufacturer (e.g., JLCPCB, PCBWay) for as little as $2 for 5 boards.
Typical production time is 3 days, and international shipping starts at $12, taking about 4 days via DHL to most locations.

You’re free to edit the design and add your own branding.

Upon Purchase, You’ll Receive:

• Eagle CAD files (.SCH & .BRD) — fully editable and compatible with KiCad

• Quick-start guide explaining how to use the files

• Download link for the free version of Eagle CAD

After purchase, you will receive a payment link by email. Once the payment is completed, the design files will be sent to you within 8 hours. We’re currently working on automating this process, but for now, orders are handled manually.

Note: You must use these files with a PCB manufacturer to produce your boards.
No pre-assembled or pre-made circuit boards are included.

These design files are intended for personal use and small production runs of your own pedals, not for resale as kits or standalone PCBs.

Project overview:

UberBolt is the newest and improved version of Superbolt, one of the most distinguished pedals in the history of JHS, a stompbox that managed to recreate the classic sound of a Supro amps of the 1960. 

It’s so acclaimed because tons of guitarists out there love the classic, crunchy, old-school overdrive tones with plenty of warmth and roundness the pedal has to offer. If you are one of them, this PCB has been specially designed for you!

Introduction

Hey! Would you like to have a pedal that lets you experience the feel and sound of the original amp that inspired players like Jimmy Page, Brian Setzer, and Switchfoot’s Drew Shirley? What are you waiting for then?! Just call an UberBolt and ride it into the homeland of the classic, amp-like rock tones. Just a warning: UberBolt can drive you through nasty tonal roads. At lower settings, you get a more subtle, darker tone. And since it’s an updated version of the original, this pedal boasts an improved taper on the volume control for a wider sweet spot.

Now that you are in, let’s check what this great pedal can do. Fits of all, notice that there’s no spiky, modern-style distortion to be found here. The control set is stray forward and will lead you exactly where you want to go: 

A Volume knob that doesn’t need to turn it much to get some serious overdrive—a Tone knob for adjusting the brightness and a Drive knob for the gain. 

The gain switch allows you to switch between two different styles of overdrive. Put it in the down position to achieve smoother and less aggressive tones that enable you to emulate the sound of an amp that’s just breaking up into overdrive – ideal for blues-like styles. Change it to the up position for a dirtier tone with higher headroom and upper-mid emphasis for that classic heavy rock tone.
