These guys make a lot of my custom wound PUPs for customers. They takes the time to listen to my needs and when a PUP isn’t exactly to my expectations, They will re-wind it no questions asked. Damn nice guys with amazing customer service
Strings and Beyond is my go-to place for strings and some supplies. They offer free shipping to Canada and their prices are amazing even with the crappy Canadian dollar. I buy lots of strings at a time to always make sure I have inventory for when guitars come in for setups and work to be done. Nothing better than putting a fresh set of strings on a guitar to really make it sound great!
General Guitar Gadgets has DIY pedal kits that I just love. I have built a few for myself and for others. If you like anything you see but don't want to deal with building it yourself, let me know and I can easily do the assembly for you.
