Jarin Winterhalt (Guitar O.R.), Steve Rozitis (R Guitars), and amplifier specialist (TBC). Setup, repair, and amp know how.

Calgary Guitar Collective is bringing three proper pros together for a practical night on keeping your rig playing and sounding its best.

You will hear from Jarin Winterhalt of Guitar O.R., a certified guitar technician and builder who has been running one of Calgary’s best known repair shops since 2005. You will also hear from Steve Rozitis of R Guitars, known for tackling the jobs many shops avoid, from neck work to major repairs, with a focus on doing it right and keeping instruments reliable.

On the amp side, we are joined by Juan Ortiz of Tone Hungry Audio & Effects. Juan has been maintaining and working on his own vintage tube amps since 2014 while playing in local bands, and since 2020 he has been professionally repairing guitar tube amplifiers as a contractor for established Calgary repair shop R Guitars. His work focuses on tube amp repair, servicing, and classic restoration, with a strong emphasis on iconic platforms from Fender, Marshall, Hiwatt, and Vox. The goal is simple. Keep amps reliable, original sounding, and stage ready.

This is not a sales pitch and it is not a boring lecture. It is a real world clinic with stories, demos, and straight answers.
