SJ Tunnel – 13


By Irvin Guitars

View Gallery

This is my small jumbo model (Irvin SJ) featuring a Tunnel 13 Redwood top. The SJ is designed to be an explosive and versatile instrument. It has the fingerstyle player in mind, yet gives them the capability to let the full sound of a sweet strum hang in the air for as long as you want it to. It is extremely well suited for alternate tunings.

The Tunnel 13 Redwood top paired with East Indian Rosewood for the back and sides on this Irvin SJ has a profound effect on one's heart and soul immediately upon hearing the rich, deep, and wonderfully warm tones coming out with each chord that's played. It is truly a one-of-a-kind instrument. Amazing response, balance, clarity, and sustain that just won't quit. A singer/songwriter's dream.
