Make a Lo-FI Arduino Guitar Pedal


This is a project for the guitar electronics geek. Traditionally guitar effects pedals used analogue circuits made up of clever combinations resistors, capacitors etc. Digital signal processing chips now allow analogue effects circuit to be simulated in software. This project shows the a prospective pedal maker how to build a guitar pedal with an Arduino for lo-fi digital signal processing..

Make a USB guitar


USB ports are everywhere these days, so why not put one in your guitar? This project from PCMag describes how to embed a USB audio interface in your guitar. This digitises your guitar's signal ready for recording on your PC's hard drive.

The project requires the following bits and pieces: an M-Audio Session USB interface, a USB panel jack, a Switchcraft 11A jack, a Switchcraft 12B jack, some aluminium sheet and screws. The total cost of parts is about $80 (not including the guitar).

Fit a Kaos Pad into a Guitar


Following on from yesterday's post about the Alesis AirFX guitar, I thought someone must have put a Korg Kaos Pad into a guitar, and it turns out some guy called Phil has already done it. The Kaos Pad is a multi-effects unit (designed for electronic musicians and DJs) with a square touch sensitive pad. As you move your finger around the pad you control the powerful effects processor, moving left or right up or down or in an arc affects different aspects of the effect.

Alesis AirFX guitar


This video shows how Carlos Vamos incorporated an Alesis AirFX into a specially designed guitar body. The AirFX is an effects unit that connects to any line-level sound source. You control the effects unit by moving you hand over the black circular bit ( which senses the movement of your hand within an invisible 3D sphere). You can move in any direction to modify the effect number of ways. OK, so you could do this with a foot pedal but where's the fun in that?
