Kia Ora Jake here. I just wanted to write a quick post in response to a few questions about guitar effects pedals. A boutique guitar effects pedal is most usually a hand built or a limited edition pedal built by electronic enthusiasts, or a modded (modified) pedal. Many people mod their Boss units for example. There`s a whole new world of quantum manipulation opportunities out there once you start buying some of the crazy and often deranged units. Obviously there`s time and a place for everything but if you want to continue along the consciousness bending, sonic roads of Jeff Beck, Jimi Hendrix, Frank Zappa, Tom Morello, Jonny Greenwood, Robert Fripp, Alan Holdsworth, Steve Hillage, Reeves Gabrels here are a few links to help you get really weird.
