Traditional Stratocaster and Telecaster models often have 21 frets. Adding a 22nd fret usually requires expensive and extensive repairs, such as extending the fretboard or inlaying a fret. However, these are homemade frets that can be easily attached with strong double-sided tape (or adhesive). They are made to fit the fingerboard width and radius (curve) of my guitars, so some adjustments may be necessary. However, they have been successfully installed on guitars owned by acquaintances without any buzzing, even when using vibrato (09-42, 10-46 gauge strings). Although these are homemade prototype frets, they have surprisingly received positive feedback from guitarist friends and repairmen, who were very impressed. I once deeply regretted cutting the fingerboard of my favorite vintage guitar and having it repaired to add a fret. However, I created these as temporary frets because I often needed to play songs that required a 22nd fret. The pitch of the 22nd fret is slightly lower, so the intonation is not noticeable when using vibrato or pressing the strings firmly. While you can firmly attach them with adhesive, removing them may leave marks, requiring you to lightly sand the fingerboard surface. The double-sided tape sold at 100-yen shops is not strong enough; I recommend using a heavy-duty type. I use Scotch multi-purpose heavy-duty double-sided tape and 3M super-strength double-sided tape. I choose the best tape depending on the fingerboard material, such as ebony, maple, or rosewood. Tested on Fender Stratocaster, Telecaster, and other company's copy models. I have not tried adding a 25th fret to a 24-fret guitar, so I cannot recommend it. Please understand that you may need to make final adjustments to fit the radius of your fingerboard. Recommended for those who are patient enough to experiment, have good manual dexterity, and enjoy experimenting, or those who absolutely need a 22nd fret in a simple way. They are made to fit the width of my guitar's fingerboard, so you may need to cut, bend, or sand them slightly. Please understand this, and refrain from purchasing if you are unsure. The impact on the guitar itself should be minimal, but it is at your own risk. Please refer to the feedback section for reassurance regarding reliability. Limited stock remaining.
