Q

What's the input impedance?

A
  • I believe its 2.2 MegaOhms. The amp/eq is really good, but the piezo is terrible. Get some CBGitty piezo and you will have an amazing set.

When tested no sound but pressing batt check button does make clicking sound- used 1/4 to TRS to 2 RCA stereo cable into home stereo aux in THNX

A
  • I built mine into a cigar box guitar. Worked well with a guitar type amplifier. Maybe there is a problem with your cable, or an impedance (sp) mismatch in your amp input.

Q

What are the dimensions of the cutout, and the outer dimensions of the trim ring? Also, Is the base of the trim ring curved at all, or flat? Thanks

A
  • I don't recall the exact dimensions. I actually used mine in my sons miniature first act guitar. I laid it against it in numerous locations until I found the closest fit to the contours of the guitar. Then I made small reference marks on the guitar. I started tight and shaved the opening a small amount at a time until … see more I don't recall the exact dimensions. I actually used mine in my sons miniature first act guitar. I laid it against it in numerous locations until I found the closest fit to the contours of the guitar. Then I made small reference marks on the guitar. I started tight and shaved the opening a small amount at a time until it fit snugly in place. Once you've scored the guitar a couple times, in most cases it will cut through quickly, as they are extremely thin. I would be happy to share pics and or a small demo. Also, don't forget that this pickup fits beneath the bridge and is quite fragile. Most bridge pcs can be removed easily and held firmly against a belt sander or block-planed and finish ground back to height with a block or even a concrete driveway. With the addition of the pickup, you want to finish at the original ht as closely as possible. Thanks & Good luck! see less

Can this be connect to clasical guitar

A
  • I've used this on two Classical' to date. The first was on an old Applause by Ovation, the second was on a Guitalele (Yamaha). In both cases, the Pre-amp and Piezo worked fine. While I wouldn't use this on a High End Instrument, I have no problems putting it to use on student or first tier guitars. Remember to measure … see more I've used this on two Classical' to date.

While I wouldn't use this on a High End Instrument, I have no problems putting it to use on student or first tier guitars. Remember to measure your saddle height before installing, as you'l need to file or sand the saddle after installing the piezo back to that height. see less
