Guitar EQ-7545R 4-Band EQ Equalizer System Acoustic Guitar Preamp for Acoustic Guitars Black (CURVE)

I've installed this unit in 3 guitars now, one being one of my personal guitars & I have no complaints. They have a full, rich sound, don't eat batteries, and very easy to install, even in a guitar that wasn't already electric/acoustic. Well worth the price.

Greetings, this may sound weird. . . . I restore antique phonographs (and vintage Reel-to-Reel tape recorders) that typically have ceramic / crystal cartridges (pickups). This device is PERFECT for matching ceramic cartridges to vintage electronics. The output is line level (-10dB), but workable with high impedance (vacuum tube) amplifiers. I bought one to experiment with. It worked so well - I bought many more. This particular install I use for ingesting transcription discs (lateral or vertical cut) for restoration and archiving.Because this little amp is designed to amplify a piezo pickup (piezo Is crystal afterall) it's perfect for vintage ceramic cartridges.-Tim, Genuine Effection Sound Recorders.

I use these in Cigar Box guitar builds and recommend them highly. Good quality sound, well constructed, easy to set up and I've used these in a number of builds. I will continue to purchase these items and recommend them for anyone doing a Cigar Box guitar build

For what this costs, it's an excellent deal. I used it to replace the old BBand/SRTn system (that are famous for failing) in my Ibanez acoustic. I needed a flatter preamp to fit the existing cut-out as closely as possible. With some modification to the guitar, it fit pretty well and did not take too long to install. I did have to use a rotary tool to deepen the bridge slot for the piezo pickup as it is thicker than the original. This was the case with my particular guitar, but may not be with others. Sound quality is pretty decent. Not quite as good as the original, and a bit more piezo "quack", but works well enough for me. Has a strong output so should drive any amp with no issues. Overall a really good deal, just not 5 star audio quality.

great little unit, I used it in a cigar box build. Easy to install, good sound for my application where I don't want top shelf sound anyways. I'll buy this again for my next build.

It’s dimensions were perfect for my needs and were described very well and accurately. I also like the ease of access to the battery

Awesome pickup! Would buy again for sure. Very easy to install. Total time took 20 min. Sound quality is better than my $200 Gabbanelli pickup. Only thing I would change is maybe if the connection was a all in one strap pin! Would’ve been awesome.

My Yamaha 335 is a standard acoustic, not acoustic electric. So I cut everything out to install this unit. It works just fine. The saddle pickup fits within the existing bridge of this guitar with no modification needed on the bridge. HOWEVER, you will have to shave the saddle to accommodate for the thickness of the pickup. Sound quality isn't the best in the world, but really what acoustic/electric really is anyway? For my purposes it was a cheap way to be able to electrify my backup gig acoustic.
