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

  • 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 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

Will this preamp work with phantom 48V power?

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

    This acoustic pickup system is great for the price. The eq is very useable and it sounds nice. Instalation is pretty straight forward but there are a few things you have to watch out for. The first thing I did was to cut the heat shrink off of the transducer. This was for better vibration transfer between the saddle and transducer. The rubber heat shrink acts as a damper resulting in a thinner sound. When you file your bridge saddle down make sure it is dead flat or you will have a string or two thats not as loud as the rest. It is a piezo system so even pressure has to be applied across the transducer. My A string was a bit thin sounding, this was easily fixed with a piece of aluminum tape stuck under the saddle under the A string. It will take some time and patience to get all strings even. I also dont care for the output jack that came with the system. I replaced it with an end pin jack designed for an acoustic. Using the jack that came with the system would have been very unprofesional looking. All in all its a great sounding system at an unbeatable price.

    Super produit, conforme à la description, livraison en France en moins de 10 jours, bien emballé. Il faut être un peu bricoleur pour installer le micro piezo sous le sillet du chevalet de la guitare, mais le résultat est super satisfaisant. Pour 5€ j'ai transformé une vieille guitare sèche en une electro-acoustique... Attention, il n'y a pas de notice d'installation, et ne pas oublier de débrancher le jack, car c'est lui qui sert d'interrupteur pour couper la pile.
