Jeff Aulich endorses these products:
Veritas Custom Guitars - I had them build me a custom Portlander model guitar. It is my dream guitar and is absolutely incredible to play. Definitely the nicest guitar I've ever owned and probably the nicest I've ever played.
Xotic Effects - I have had a BB Preamp on my board for the past 8 years. It's been on my board longer than any other pedal and is one that I will probably never get rid of. I have also used their EP Booster and SL Drive. All of their pedals are incredible.
