AcoustiFex Go, Acoustic Guitar Pickup, Preamp and Effects System

This thing is pretty cool! I am just using it acoustically. Can’t add anything as to how good the pickup itself sounds. Note: If you are using it like me, you have to plug in the trans mic, and the input jack to get it to turn on for the first time. I thought mine was broke for a min. Happy with product!

The outstanding feature of this pickup is that it amplifies your guitar's sound, without plugging into an external amplifier. It does this with a small transducer that adheres to your instrument's back. You get delay, and reverb, plus the ability to blend an electric pickup sound, with a small microphone that picks up the acoustic sound coming from your own guitar body. You can also plug-in with the usual 1/4 inch jack.In my opinion, the Kepma pickup is much better then the sound generated by piezo pickups, which can sound odd, and make a kind of "quacking" sound. Best of all, even though my monitor was 3 ft from me on stage, there was no feedback from the Kepma. It's also great that you can use the pickup/amp temporarily, before you drill any holes into your guitar body. After trying it out on stage, I've decided to make the installation permanent. The only slight drawback is that it does cover up half of the sound hole. Of course, many pickups do that. This mutes the sound when not using the device; however, all you have to do is turn it on and the true voice of your guitar is unchanged, yet louder. The battery is replaceable, and holds it's charge for many hours, and there was plenty left after 4 hours onstage. Surprisingly, it doesn't take long to recharge via its USB connection (about 3 hours).Customer service is outstanding, and though they don't have online purchasing as of yet, they will be up soon (as of this writing in September 2019). I accidentally ruined the transducer while trying to remove it from my Breedlove Acoustic Bass (yes it did work on the bass). I should have used a plastic paint spatula to get underneath the adhesive, but not doing so broke the voice-coil off the transducer. They shipped one out to me within a day of my email inquiry...not even Amazon, the gold-standard of customer service can top that (though they frequently have as good a response). I have a few other guitars that I'm thinking of fitting with one of these Kepma pickups, but I want to check out their line of guitars first. Enjoy.

Installation:First and foremost -- NO SOLDERING!! Thought I'd put that first for those who want to skip on. I wish I had better feel for where the device goes on the inside of the guitar. I felt like if I place it wrong it's not going to sound right. Other than that the installation wasn't bad, but with the end pin it would be nice to have something to help you pull it through. What I do is ruin a cheap 1/4 cable by removing all the rubber or plastic so that it's small enough to fit through the end pin hole, and feed the cable through the hole until you can reach it in the sound hole. Plug it in to the endpin jack and pull it through. Put a very small amount of thread lock on the strap button that screws on -- it will come lose with playing, and all my acoustic guitars do that with this kind of jack. The rest is just simple, plug in the two jacks and it works.Sound Unplugged:This is why I gave it only four stars. From a player's standpoint the change in the way my guitar sounds is subtle. I wasn't impressed off the bat, I'll be honest and I nearly packed it back in the box. I've got a good, all wood guitar with an excellent spruce top that sounds great on its own. And if you've got a Martin, or Taylor you know what I am talking about. It adds that needed spark and makes it sound just a bit better. So I really notice now when I don't turn it on, so in the guitar it stays.Sound Plugged in:This is worth buying as it's one of the best sounding pickups I've owned, and I've had a Fishman rare earth, I used on a Martin. Then again, I have three pickups. My original setup had a Piezo with a microphone that plugged in with a 1/8 inch jack -- which is the size of the output jack on the Kepma. So I plugged the Kepma into that, so I have the PIezo and the Kepma mic, and Magnetic pickup, and the three of them blended together sounds very nice. I can also blend the piezo and the Kepma, and use the 5 band EQ of my onboard electronics.All in all it's a nice unit. The only other thing I really don't like is the big green light -- I don't need that. a smaller and much dimmer light is what I'd prefer as it stands out on a dark stage. black electrical tape fixes that too.

I love the Acoustaflex. Gives a little reverb on a campfire guitar and makes it sound studio quality. Holds a charge a long time. I have used it for a few years now and it never gets old.
