Description & Condition
Michael Tobias Design (MTD) was founded in 1974 by Michael Tobias, who has made a living making musical instruments.
It is highly regarded by top bassists worldwide, including Andrew Gouche, Robert ""Bubby"" Lewis, and Jerry Watts. (Titles omitted)
Despite producing only about 10 instruments per month, its quality is widely known.
This is the flagship model, the 635-21.
This model number indicates a 6-string model with a 35-inch scale length and a 21-fret fingerboard.
This is a fretless bass that has been modified to be fretted.
The body is primarily made of ash, the neck is maple, and the fingerboard is wenge.
The body top uses beautiful exotic wood, giving it an attractive look characteristic of MTD.
Due to a problem with the truss rod, we replaced the rod and consequently replaced the fingerboard at our shop.
Furthermore, we refinished the guitar in our shop to fill in paint scratches and screw holes.
The fretboard and paintwork were restored to a similar appearance to the original condition.
Although significant repairs were performed, this is precisely why the guitar is in such excellent condition.
There are absolutely no concerns regarding playability.
The pickups and preamp are the familiar Bartolini custom pickups.
The EQ, in its flat state, is massive, clear, and fast.
Even when boosted, it doesn't break down; it becomes more solid and impactful, or sharper and more intricate—highly versatile.
Because it possesses a refined balance in its basic state, the sound doesn't break down even when the EQ is actively manipulated, and even when the pickup balance is shifted, it produces a powerful, bass-like sound.
The frets have approximately 95% remaining.
The truss rod is in good condition.
The neck is in good condition.
The body and paintwork are clean, with only minor scratches near the neck joint. The metal parts and pickups show signs of wear.
The logo on the headstock is faded. The knobs are somewhat loose when pulled, although there is some resistance. There are no issues with normal playability.
The electronics are in good condition.

During setup, we used D'addario EXL strings, highly trusted by professional musicians.
Characterized by a powerful attack and rich harmonics, these strings truly deserve to be called a standard.
These high-quality strings bring out the instrument's performance and character to the fullest, so please enjoy them as well.
GIB's craftsmen will adjust the instrument for easy playability before delivery.
