Please see the [Terms of Use] for details.
Frequently Asked Questions
Q. How much do guitar and Bass repairs and adjustments generally cost?
Please check the Guitar and Bass Repair Pricing page for details. We will provide a free estimate after inspecting the actual instrument.
Q. How long does a repair take (turnaround time)?
A: Even for minor repairs or part replacements, we generally need to take the instrument in for a thorough inspection before proceeding. It will take at least a few days, but if you have a specific schedule in mind, we’ll do our best to accommodate your needs. Please obtain a repair ticket in advance or contact us via chat to discuss your situation.
For major repairs involving fret replacement or refinishing, it may take approximately 2 weeks to 1 month. If you’re in a hurry due to a live performance, recording session, or similar, please contact us via chat or another method in advance.
Q. Can you repair instruments purchased at other stores or older vintage instruments?
A: Yes, of course! At TCGAKKI, we handle a wide range of instruments, including those purchased elsewhere, foreign-made instruments, vintage instruments, and even instruments of unknown make.
Thanks to our repair staff—who have supported TCGAKKI (Kubokan) for over 35 years of experience with various instruments—we can address each instrument individually, regardless of its condition or history. Please feel free to entrust us with any instrument you have.
Q. If the repair costs seem likely to be high, I’m unsure whether I should have it repaired or buy a new one.
A: While it brings us great joy to restore your cherished instrument, there are cases where the repair costs may exceed the instrument’s current market value.
In such cases, instead of repairing it, you can trade it in and “upgrade” to a new instrument from our used inventory.
At TCGAKKI, even if you purchased your instrument elsewhere, we’ll increase the trade-in valuation by 10% when you choose to upgrade.

Q. I live far away—do you accept repairs by mail?
A: Yes, we accept repairs via mail or courier.
To ensure the same level of precision and explanation as with in-person requests, we proceed by carefully confirming the symptoms and your preferences.
Please start by discussing the symptoms with us via chat.
We’ll also provide clear instructions on how to pack your instrument and the shipping process.
Q. Can I request “regular maintenance” or “adjustments” even if my instrument isn’t broken?
A: Yes, please feel free to request these services.
Even something as simple as a neck adjustment or string height setup during seasonal changes can make your instrument surprisingly easier to play.
By having us check the condition of your instrument regularly, we can address issues before they develop into major repairs, which often results in lower costs for you.
It’s perfectly fine to bring your instrument in even if you’re just thinking, “It might have become a little harder to play lately?” Please feel free to bring it in.
Q. Can I consult with you about “customizations” such as pickup replacements or wiring modifications?
A: Yes, we’d be delighted to help. Our expert staff will carefully address requests such as “I want to get closer to my ideal sound” or “I want to customize it to my own specifications.”
We can handle a wide range of projects, from pickup replacements, circuit upgrades, and tuning peg replacements to large-scale modifications involving woodworking.
We also carry a wide selection of replacement parts in-store, so you can plan your project while viewing the actual items.
