Pedalboard Building & Wiring

We love our pedals, and oftentimes we get asked to build pedalboard for customers. Whether it's solderless or soldered, mono or stereo, switchers or MIDI, flat board or angled board, we offer handful options to choose from to suit your need. 

Pedal boards and rigs are instruments in their own right these days and are as personal as your guitars; no two are the same and we are here to listen to you and to deliver a custom pedal board solution that fits your budget, your music and your playing needs.

We will work with you to provide a comprehensive plan that eliminates noise, creates intuitive and comfortable layouts, future proofing adaptability with safety of travel and ease of ‘load in, load out’.

We will listen to you and walk you through the various options and associated costs. We can also supply the components for you to self-build or we can deliver a complete solution including custom design, cabling, pedal mounting, arrangement and power supplies.
