1980

Bob Bradshaw founded Custom Audio Electronics.

Each effect went into its own loop, and the switching moved to one controller at the player’s feet.

Before 1980

Each pedal came with its own switch.

The fuzz had one on top, and the wah had a switch marked Straight and Wow-Wow. Five pedals meant five switches in five places.

Drawing from U.S. Patent 3,213,181, 1965: a guitar, a pedal and an amplifier, and the pedal circuit with its on and off switch — 1965 · U.S. Patent 3,213,181 · Tone modifier

Drawing from U.S. Patent 3,530,224, 1970: a foot-controlled circuit with a switch marked Straight and Wow-Wow — 1970 · U.S. Patent 3,530,224 · Foot-controlled preference circuit

The part we inherited

None of this starts with us.

Bob Bradshaw started building switching systems in 1980, and Custom Audio Electronics still builds on that plan. RJM carried the standard forward and put MIDI control in the same box. We spent months studying their work before the first board of our own came back from the factory. Koinos PLS 8 would not exist without either of them.

Custom Audio Electronics and RJM are trademarks of their respective owners and are not affiliated with Judahs.

We set out to learn that sound. Not to beat it.

Soundcheck is running short. One preset needs one small change. Out comes the laptop.

The loops are still at the player’s feet, as they were in 1980. The decisions moved to a laptop.

The old way: one box, one job, many cables

The part we did not

What we chose not to inherit is the place where decisions happen.

Setup lives on an 8.88-inch touch display on the unit, so a change at rehearsal or mid-show does not need a laptop.

Input impedance

Even the input impedance is yours to decide.

500kΩ

1MΩ

Brighter

The setting changes the load your pickups see. A relay switches it in the circuit, and you choose it on screen.

On the screen

Performance view: bank, page, chain, tempo.

Chain order, dragged with a finger.

Preset edit: input, buffer, loops.

Pedal manager: loops, MIDI, relay and ToneX in one list.

Manual mode: ten switches, one pedal each.

One switch, its messages: PC, CC, notes.

ToneX One over USB: slot, type, blocks.

1,200 songs. 100 setlists.

Editor

The laptop is optional.

When you want to edit on a Mac or a Windows PC, Judahs Studio is the editor. It works on the same banks, songs and setlists the unit holds, and it’s free.
