| Q. | All guitars are not the same so how do you know exactly where to locate the LEDs? |
| A. | Based on the scale of your instrument, a mathematical formula is used to precisely
determine the correct LED locations. You can click here to see instructions on how to measure the scale. |
| Q. | What if I cannot find space to mount the battery pack anywhere on my headstock? |
| A. | Just return the un-mounted FretFX for a refund minus shipping charges. |
| Q. | Are the LEDs located in the same locations for fretted and fretless basses? |
| A. | Fretted instrument LEDs are centered BETWEEN the frets and
fretless bass LEDs are located ON the frets. (Note - The LEDs begin at the 1st fret position on fretless instruments) |
| Q. | Will FretFX fit on a headless bass like a Steinberger? |
| A. | At this time there is no solution for a lack of headstock mounting space for the battery pack. |
| Q. | Can you make the battery pack connect at the other (bridge) end of the LED array and mount the battery pack somewhere on or inside the body? |
| A. | Due to the design of the fabrication jigs, molds, and the material curing process, FretFX cannot be reverse wired with the battery pack at the other end. |
| Q. | Can I remove FretFX from one guitar and install it on another? |
| A. | The process of removing FretFX will not harm your instrument but will destroy the LED array. |
| Q. | Can I adjust the locations of the LEDs after I receive the product? |
| A. | No, they cannot be re-located within the array so the CORRECT scale must be specified during purchasing. |
| Q. | Do I include the nut itself when measuring for my scale? |
| A. | NO, do not include the nut. |
| Q. | Can I order the LED array separately without the battery pack so I can route my own power from inside the body cavity? |
| A. | FretFX battery packs have a specialized circuit designed to regulate current and extend battery life, which guarantees the correct illumination and prevents random LED failure (burn-out). In an effort to maintain the quality and reputation of our product and it's ability to "perform as advertised", FretFX components are not sold separately. |
| Q. | Will FretFX interfere with a wireless setup on a guitar? |
| A. | Not at all. There is no RF generated by FretFX. |
| Q. | Does the use of lemon oil on the fretboard affect the FretFX array? |
| A. | Lemon oil does not affect the array, as long as you don't soak the adhesive strip with excessive amounts of oil. |
| Q. | How many LEDs can I have in the array? |
| A. | A maximum of 12 LEDs can be driven by the battery pack. |
| Q. | Are the LEDs visible when looking at the front of the instrument? |
| A. | Yes they are somewhat visible from the front, but not nearly to the extent as from the top. |
