Black JZZ GTR ™ Tuning Crewneck Sweatshirt with Sleeve Notes Standard & 7-String Tuning Guide
This crewneck sweatshirt is a quiet companion for guitarists and teachers who live in notes and practice rooms. The contrasting stitching gives it a vintage, handmade vibe while the embroidered tuning guide along the sleeves turns the garment into a functional reference — glance down and find standard tuning or the extra low strings for seven-string work. It settles into studio hours and late-night rehearsals, keeping shoulders warm without weighing you down. The clean crew neckline and classic fit make it easy to layer over tees or under jackets, and the tubular knit keeps lines smooth so your gear looks intentional on stage or in class. For educators, the sleeve markers act as gentle reminders during lessons; for players, they’re a small, steady tool that makes practice feel thoughtful and deliberate.
