Hello, this is Mogi from TC-TUNE.
Previously, Tanaka from TC-TUNE posted a video showing him converting a junk Warwick into a headless bass.
Be sure to check out the video here!
Tanaka boldly modifies a junk Warwick! An unexpected headless conversion!?
Instead of simply repairing a Warwick with a broken neck, Tanaka took the bold step of converting it into a headless bass. 
It’s a Warwick, yet it has no headstock.
That’s the first thing that really catches your eye. 
It’s a modification you don’t see very often, but if you look closely, you’ll notice a lot of attention to detail.
The Warwick logo that was originally on the headstock was cut out and transplanted to the 12th fret. 
Furthermore, the serial number area has been modified while preserving the original markings.
Although the original headstock is gone due to the headless conversion, what makes this bass interesting is that elements from the original instrument have been preserved in different locations. 
The area around the bridge has also been modified to fit the headless parts.
It’s a pretty bold move, but the more you look at it, the more you start to think, “Actually, this might work.” 
After posting this video, we actually received inquiries from customers asking, “I want to do the same thing.”
I’m happy just to know people find the video entertaining, but it was really impressive that it actually inspired some viewers to think, “I’d like to try this on my own instrument.”
When people think of TC-TUNE’s work, they might mainly picture repairs and adjustments, but since this particular instrument was acquired as junk,
“Since we have it anyway, let’s not just fix it normally—let’s try something a little different.”
That’s how it all started.
It’s an idea that’s half a bit of a prank, but sometimes that’s exactly what makes for an interesting instrument.
Guitars and basses are sold as finished instruments, but I think part of their appeal is that they can gradually change their appearance based on the player’s mindset and preferences.
Even a small change in appearance can be a matter of great importance to the player.
“Maybe this kind of spec would work.”
“It’d be fun to make it look like this.”
“If it were my own instrument, I’d want to change this part.”
That kind of thinking is also one of the ways to enjoy musical instruments.
And this year, we’re hosting our Custom Guitar Contest again!
For this contest, you can enter not only instruments you’ve customized yourself but also those customized by our shop!
Instruments that have had parts replaced or specifications modified at TC-TUNE in the past.
Instruments where you contributed the idea but someone else did the work.
Instruments that were adjusted to better match your preferences during repairs or setups.
We welcome entries featuring all of these types of instruments!
