About Us

Ever since I started working at a music store at the age of 16, I have had a passion for the electric guitar and guitar effects. My journey started by rewiring electric guitars, and replacing pickups, and this gradually progressed to doing more advanced modifications, such as on board preamps and active guitar systems.

As a guitarist myself, I found that I was never really 100% happy with the sounds that my effects pedals would produce. I did know quite a bit about sound reinforcement for PA applications, and the importance of selecting the right components for the job at hand.
