SG-1

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.

Item does not work.

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.

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.

This is a really good pick up. The concern that most buyers expressed was that it was fragile. The tone quality is really good , very clean. In the instructions, there is a drawing, of attaching a cable protector to One’s belt or clothing. I think this is not a good idea. I decided to attach the belt clip to the guitar with double stick tape (photo uploaded). This will hopefully insulate the very thin wooden pickup from an inadvertent pull that could break it. To me, this is a much better solution and clipping the belt to some part of my body.

I bought it for my puertorican cuatro and works perfectly! It picks every single of the ten strings. Even though the description never mention the compatibility with the puertorican cuatro, I would recommend to add it in the compatibility list. I shared some pictures for your reference. Be advised that I'm lefty, so that's why the pickup looks upside down.

The pickup doesn't fit between the bridge and the string pins. You can't even install it correctly. Hums terribly - a real noisy low frequency hum. If you have a contoured saddle, it won't lay flat against it. Overall, perhaps it might work on some guitars, but a total bust on every count for me - and my guitar is not small - just a standard guitar. If that's what you have, don't bother. It'd be a waste of time.

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.
