『TC-TUNE is the exclusive repair team for TCGAKKI and Advance Guitars.』

"Why would a used and vintage specialty store need an exclusive repair team?" Some might wonder.
The role of "TC-TUNE" is to "create TCGAKKI's products."
Every instrument sold at TCGAKKI undergoes repair, adjustment, and inspection by TC-TUNE. We thoroughly disassemble every instrument purchased from our customers, clean it, repair any damaged parts, and perform proactive adjustments to maximize the instrument's potential.
TCGAKKI・Advance Guitars values delivering "playable instruments" to our customers, and TC-TUNE supports this philosophy behind the scenes.
As a specialist in used and vintage instruments, TCGAKKI・Advance Guitars requires an in-house repair team.

It's a specialized repair team dedicated to restoring instruments to a condition worthy of being called "products from a used and vintage specialist store."
TC-TUNE maximizes an instrument's potential and focuses on improving playability. We want our customers to be torn between "look" and "sound" when choosing an instrument.
We don't want you to think, "I like the look, but it's hard to play..." or "The look isn't great, but this one plays better, so I'll choose it." That's precisely why TC-TUNE maximizes an instrument's potential and is dedicated to its playability.
Furthermore, at TCGAKKI・Advance Guitars, we believe our relationship with customers doesn't end with the purchase of an instrument—it's just the beginning.
As the repair team, TC-TUNE also aims not just for "instruments that work fine at the time of sale," but for "instruments our customers can use for a long time," with the goal of walking alongside our customers' musical lives.
