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

The media could not be loaded. 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.

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.

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.

The saddle pickup was inadiquate, replaced withA better one, increased sound quality a little, poor circuitry for piezo pickup, saddle balance knob allows adding internal microphone, internal mic sounds outstanding.Overall well worth the cost.

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!
