KNASG-1 Bridge-Mounted Piezo Pickup for Acoustic, Steel-String Guitar – Natural Tone, Country, Folk, Rock, Lightweight, Detachable, Easy No-Mod Installation, Passive No-Battery, Handcrafted in Europe

Such a simple concept - and worked incredibly well for me. Installed on a dreadnought sized fender acoustic using a modeling amp with the acoustic settings - sound just jumps out. I was worried it would favor the treble given the placement of the pick-up - no worries. Crisp, balanced and clear. I have a piezo saddle set-up (with pre-amp) I was going to install but couldn't bring myself to cut this guitar up (I've ruined a few....). Glad I used this instead. One caveat - don't think this would fit on a parlor sized bridge. Final note - the company sent me an extra cable so one goes with the guitar case and the other stays by my amp. Couldn't be happier.

The pickup is just as described. It fits perfectly on my Martin guitar but there isn't enough room for it on my Epiphone 12 string or my Michael Kelly 6 string.The sound is clear and clean. I've only used it once so far to record onto a laptop and I pleased so far.It does look fragile, but I don't know how to avoid that and have something fit under the strings.

Like most guitarists I've spent too much time and $$ on the elusive shibboleth of Acoustic Tone. Pickup designer Lloyd Baggs once said that though it's often maligned, the undersaddle piezo pickup has been and remains the true go-to workhorse for live music since the 70s. This particular piezo pickup is mounted between the saddle and pins on top of the bridge and it's brilliant and simple. Why didn't anyone think of this before? I use the KNA SG-1 on my Travel-Air VAMD40 travel guitar, the one with the folding neck. It's easy to install with a folding neck -- no loosening or tightening strings. In terms of size, the fingernail file-sized stick plugs in with an unobtrusive, detachable 1/8" cable (included). The other side of the approximately 8' cable has a standard 1/4" jack for a guitar amp or mixer. I really like the fact that the cable is detachable. Very nice glossy finish on the jack's treble side. My only suggestion would be offering it in ebony black in addition to natural wood. Also, I strum aggressively so a right angle away from the sound hole, though it would probably be a bit unsightly, would help me from occasionally brushing my hand up against the pickup. The sound is natural and perfectly balanced. One tip: try turning your eq all the way up and then subtracting to taste. The reason for this is that any potentiometers (knobs) are by nature tone sucks, so this passive pickup to me sounds fullest and richest with all knobs at or near 10. I'm sold!Update 5/9/2019. I'm taking off a star because the logo cap piece came unglued and fell off. This would be excusable for a $35 pickup. As it is, it's overpriced but of course usable.

I have a 00 Martin. The pickup did not fit.

This sounds as good as my factory installed under bridge piezo pickup on my Yamaha FG800C.I installed it on my solid top mahogany Mitchell, and the sound is very true and realistic... it sounds better than the sound hole pickups, as they get the vibrations from the strings vs. the vibrations from the soundboard and bridge this KNA does. When not in use, I simply leave it on the guitar and it doesn't affect the natural sound at all. Great invention and design, simple and NO drilling into your precious instrument.

This will provide decent sound quality from your acoustic guitar, but the end where the cable plugs in doesn't fit flat on the bridge and it broke. I don't even remember having stressed it in any way. They have other good products, but this one isn't one of them.

I was able to install it on my Goodall RCJ, but the pickup is too wide to fit Larrivee L-09 and Martin M-36. It is too bad because it is not too expensive, it is easy to install and remove, and it sounds fine. Even on my Goodall, it does not lie flat on the bridge, although this does not affect the sound. If they could make it a little smaller, I would buy one for each guitar.

Well, my KNA SG1 arrived today. Installed it (if you can really call it installing...I loosened the strings, slid the pickup behind the saddle, tightened and tuned the strings. Easy peasy!) and it sounds amazing for a passive pickup. I installed it on a 2006 Guild D40 and it tranfers the very natural sound of the guitar to the amp of your choice. I plugged straight into my 24 track Alesis board and was overjoyed at the sound quality. It actually sounds better than my Gibson Hummingbird with it's L.R. Baggs pickup system. Well worth the price of admission. I will probably invest in a better cable, as the one that comes with it seems a bit flimsy.*UPDATE*Well, it was good while it lasted. The downfall to this pickup is that if you use a better cable than the one that comes with it be prepared to break the pickup. I turned slightly while sitting down during a recording session and the pickup broke under the weight of the cable. I'm serious! I did nothing more than turn just slightly and the end of the pickup just broke off. It sounded great, but the pickup itself is too flimsy for use in the real world.
