Title:

Digital Guitar Effects Pedal

Guitarists of all levels utilize effects pedals to get the desired tone out of their guitars. Often times this leads to having a large pedalboard filled with an array of different pedals interconnected. Most of these pedals are analog and only provide one effect. This 1:1 pedal to effect ratio not only leads to more pedals but can cost the guitarist a great sum of money. Digital effects pedals are different from analog pedals in that they can implement multiple reconfigurable effects on the same device. The issue with the digital effects pedals on the market is that they cost upwards of $500 and even $1000. The basic model of a digital pedal is relatively simple. An ADC converts the guitar signal to a digital signal, a processor performs the effect on the digital signal, then a DAC converts the digital signal back to analog. Hardware for an ADC, DAC, and a fast processor is available for far less than $500, so theoretically a digital effects pedal can be made for a fraction of that. This project's goal is to create a digital multi-effects pedal for a guitar, finding a balance between effect count, effect quality, and total cost.
