Kmise 5 Band Guitar Preamp EQ Equalizer Piezo Pickup Tuner Amplifier 1 Set for Acoustic Guitar with Mic LCD Display

I had an roughly 2008 Fender acoustic/electric (Pre-Fischman model) no frills, no tuner, very basic acoustic-electric dreadnought . I wanted to upgrade the electronics to get some additional sound quality and a built in tuner. I came across this product in my search and after much reading decided to give it a go. The control box was significantly larger than my original controller (not really surprising). I used my existing fender piezoelectric in the bridge instead of the included. The plug size was the same and seems to work perfectly. The internal mic does only plug into the inside control box with the standard (headphone style) plug and turns loosely inside the guitar so be sure to tie it down somehow so it does not move around inside the guitar as it is VERY sensitive and would make an enormous sound if it struck the body. I also modified my install as my guitar already had a guitar jack and battery port. So I opted to bypass the cheap feeling clunky combination battery/output jack box. The display and LED's are sickeningly bright (a common problem in cheap electronics) but it does not affect the wonderful sound this unit produces. The blend between Piezo and Mic are simply a game changer. My only 2 negative points about the controller... #1 way to bright light and display (for a dark room but probably great outside in the park) #2 you have to cycle thru multiple button presses after you turn the tuner on in order to reach Auto Guitar (annoying since this is built into a guitar why is that not default??). Overall I love the sound and feel this was well worth the price for what I needed.

I replaced a dead B Band preamp in my Washburn classical guitar. I was able to use the same cut out but had to enlarge it quite a bit. I was able to match the contour of the guitar pretty well. I made a template and used painter's tape to protect the finish. I tried a Dremel tool to enlarge the opening but that was slow and dusty with a cut off disc. I ended up using a quality variable speed jigsaw (think yellow and black) with a fine tooth blade. The painter's tape prevents splintering of the wood. I cut to the inside of the line on the template and finished up with a sanding block and files. It was a tight fit but there isn't much room for error so better safe than sorry. The piezo that came with the preamp was thick and short. I tried to order something flatter and longer but when it arrived it was about the same length as the one I already had so I returned it. I tried another one but it was dead. I finally ended up using the original one that came with the preamp. I had to modify the saddle a lot and drill another hole in the bridge in order to fit the pickup correctly under the strings and route the cable to the preamp. The battery compartment and inputs required enlarging the opening that was already there. I didn't have any options about where to place this component because of the opening that was already there. This must be placed with the contour of the guitar body. Once everything was installed I plugged in and tested it. The piezo alone is very plucky. Blended with the mic it's actually pretty nice. The tuner seems to be functional but kinda like "nothing, nothing,then sharp, then nothing, then flat. The power button turns off the light and tuner but the the pickup and controls still work with the power off. I assume this means the battery is activated by inserting the plug into the input jack. (So be sure to unplug the cable or you'll drain the battery.) Over all I don't regret doing this project but it is not something you want to attempt unless you are confident in your skills. Cutting openings in a quality instrument is not for the faint of heart or novice. This preamp and pickup kit is inexpensive and that is appealing but I was apprehensive about the quality. Time will tell about the long term quality but it looks good and with some tweaking, it actually sounds good. It would be easier to install if they provided a template and if the piezo pickup wasn't so thick. I had to modify the saddle quite a bit. I notched the saddle to accommodate the pickup rather than sanding the saddle all the way because that would have made the saddle unstable in the slot. Good luck with your installation. I think you might be happy with the sound.

This is a very cool electronic amplification for an acoustic guitar, especially for the money. Installation is NOT for beginners as one must deal with many concepts of contour, alignment, wiring, etc. But, after thinking it through, I found it pretty straightforward. The sound is very good and the tuner works great. Looking forward to more testing and hope it does not give up any ghosts as complained by others. Probably people that work for Fishman who charge hundreds of dollars for essentially the same hardware. BTW. and true to me, I took it apart to see the innards. Fairly clean circuit boards logically placed. Had initial trepidations about the 2nd extra large hole, but love the high/low impedance inputs and battery combo. The mic mix is also very cool. Nice work, my Chinese friends. Let's hope our governments stop screwing with our relations. My Chinese friends are very nice and we, Americans, get along very well on that basis. Don't let the politicians goaded by the gloabalists create divisiveness to try and control us.

They should have included templates to use to mark the cut and screw holes. The bends in the face plate are ever so slightly different from one another. So to make it sit close to flush i had to do extra wood work on my guitar. The gasket glued on it is trash. I had to trim a lot of it off which made it look bad so I pulled it all out used gaft tape intead. The piezo itself is badly wired and weak, it hums until I make grounded contact with it. The microphone is potent and ultra high frequency and doesn’t pick up low frequency that well unless its an Airplane of a thumping system driving by. Also mids distort too easily. But hey it was cheap and I can use other equipment to make it sound good.

Easy to install with dremel and tape. Fits nicely in baby Taylor. No instructions, but found some online on youtube. The instrument jack can go either way but is better one way. 2 hours total installation time..also, upgrade the microphone if possible. Total materials needed: dremel, painters tape, file, screw driver, Sand paper 500 grit, pencil. How does it sound? The adjustable internal microphone adds depth. Another comment. You have to have the right bridge for the piezo to fit inside to use this pick up. It should work for most guitars, but for example, my acoustic Takamine has a two piece bridge and this kit does not work. Have fun!

OK, so I check everything and decide to go through with it. Not for the faint of heart ! Remember you can't go back after you cut holes into your instrument. That being said, you really need the necessary tools in order to accomplish this. There are NO instructions, so it's best to look on YouTube. I decided to go ahead & give it a try, but I do not recommend this product. My opinion is you're much better off buying an acoustic electric guitar instead. For one, mine doesn't shut off & I can't turn the tuner off either (which you have to press the button for each string to tune, when it works). The tuner goes from A to G# alphabetically. It does NOT automatically go from string to string (E-A-D-G-B-E). The 5 Band Equalizer does very little. The sound is somewhat less than desirable. Does it work? Yes it does, but does that equate into a great sounding instrument? NO NOT AT ALL !!! (PLZ do NOT use on a quality instrument) Now that it is installed, there's nothing I can do. It is what it is. I guess I can Gorilla glue the pieces of wood back onto the guitar, but a rather unsightly cure. Then there's the nasty feedback from the microphone. Cheap is Cheap ! This is CHEAP ! Like I said, mine won't shut off ! Neither will the tuner ! So if you do decide to go for it be advised you may not be very happy with it. I'm gonna see if there's another branded Pre-amp I can swap out with it. (this may make a good practice run on a cheap guitar before installing a diff. brand onto a good guitar) My best advise is to make a TEMPLATE on paper, then tape it to the guitar. Use PAINTERS TAPE (blue) with a center line drawn on BOTH the template AND blue tape (affixed to the body).This way it's straight ! Another consideration is that these pre-amps have a curve that FAR exceeds the curve of a guitar. So it will never sit flush on the guitar body. The screw holes are VERY important. Triple check your template. It's difficult to work without the proper tools. I recommend the following: A Dremel (or similar rotary tool) this is crucial. A cutting tool attachment. (if you're really well versed you may use a multi-tool with a SMALL blade) take your time here. You should also have a digital caliper or a micrometer because you need the exact height for the saddle to be cut. I dragged my caliper across the bridge then colored the line with a black felt pen. I used the Dremel with a sanding disc to get close to the correct size and then used sandpaper and a "fine" file to make it flat. A small hole needs to be drilled into the saddle for the Piezo that goes into the bridge closest to the HIGH E sting to feed the wire into the body. (remember to press the Piezo firmly into the saddle so it sits flush) This is where you get the "best" electrically produced sound. I recommend using several wire managers with the sticky backs. Small sized ones will work fine. One will need to be placed onto the preamp itself (to hold the microphone from disengaging as I found out) and another for the output jack/battery wire within the body. Personally, I wish I never did it, but it's too late. That train left. I wish all of you the best of luck ! Again my advice is "just say no"!

I got this bridge pickup in the mail two days ago and I installed it on my Puerto Rican Cuatro. I was very nervous about cutting into the body of the guitar since I'd never done one. However, after watching a YouTube video on installing a bridge pickup on an acoustic guitar, I was able to do it. I cannot stress enough to take your time with it and do it right. Be sure to check for any bracing that might be affected by it and make your adjustments that way. I used painter's tape to protect the finish of the guitar while I cut the opening. I also made some templates of the pickup and battery pack and then traced them onto the taped area (See pictures) after all was installed, I used the provided screws to secure the module in place and tighten them by hand. They are not the best in quality and very tiny so again, take your time with it. To cut out the opening, I used a dremel tool with a cut off wheel. I couldn't be happier with the end result and the sound controls are fantastic!. For the price, it's a no brainer! If you're handy with tools and crafty, this is a go for you!

I got this for an acoustic/electric upright bass build(think Takamine TB10). The included piezo was not usable for this build, but that was planned. In place of the saddle-piezo, I used a pair of piezo discs epoxied just to the “neck” edge of the bridge plate. The piezo sound is powerful and resonant with outstanding sustain. The mic alone is weak, but when blended with the piezos, the whole is very good, either pizzicato(plucked/slapped) or arco(with a bow). I’m not sure XLR out works, and my initial perception is the battery will drain even if the 1/4 plug is disconnected. Both of these issues need further testing.

Lo utilicé para convertir mi guitarra acústica en electroacústica

Working good on Yanaha acoustic

Got here quick box was undamaged and was the second one i bought first one for my Denver guitar and the second one was for my son guitar and they both worked amazing and I know that this work well and easy to install will order more as needed

worked great no problems so far whatso ever, I watched DYI videos on it first, then went at it , taped up everything .I just cut holes with drilling a few holes so I could fit blade to my hacksaw then carefully did around edges of holes with a file ,as I never had a Dremel , Quite well worth the 27$ cad I paid IMO

Lo usé para reparar una guitarra electro-acústica. Funciona muy bien, el sonido es bueno. No usé el micrófono debido que el que estaba en la guitarra funcionaba bien. El afinador es un poco complejo de usar si no sabes los tonos de cada cuerda. La base de la batería entraba un poco justa y eso hacia que fallara la alimentación, con una lima lo ajusté y quedó funcionando bien.
