Did what it was intended to do.

L’ho comprato per non modificare la cassa della mia Acustica ed è risultato un un buon compromesso peccato che il cavo genera un rumore di fondo fastidioso. Avrei gradito di più avere solo il cavetto da 3,5 a 6,35 e di buona qualità.

Je m’étais renseigner avant de l’acheter, je trouvais le concept super.Ayant un soucis de préamplificateur sur ma guitare et n’arrivant pas à choisir un adapter en remplacement, j’ai décidé de prendre le SG-2. Une belle surprise, au premier abord il parrait vraiment fragile ce qui fait peur.Je m’y suis repris à deux fois pour bien l’installer (j’ai connecté le piezo directe à l’ordinateur pour vérifier ce que je recevais), mais une fois installé, ça marche vraiment bien, on a un son qui est juste, le piezo est vraiment très efficace et discret. Le bouton de volumes permet de gérer plus facilement les passage au doigts ou mediator. Les câble fourni font le taff, mais je ne sais pas s’ils dureront.En attendant, je ne regrette absolument pas mon choix. Je conseil cependant de faire attention quand on transporte la guitare avec le piezo dessus (risque de casse ? Peu probable dans une case, vigilance dans une housse!)À part tous cela, vous pouvez y aller les yeux fermés !!

The clarity of the sound is amazing. Volume control allows for adjustments while on stage. Great product.

My electronics on my Ibanez stopped working. They don't support it anymore, and having more holes in my guitar was not an option.Easy to install, read the instructions twice, looked at the picture on the box...loosened the strings, positioned it and tuned it up. Plugged it in and was playing in under 5 minutes. I noticed that the pickup makes a knock, if you touch it, much like a microphone if you tap on it, but after adjusting my playing...it isn't an issue. Sounds great, happy that I got the one with a volume control.

Cuando me llegó lo coloqué y aproveché para poner cuerdas nuevas. Al enchufarlo descubrí que daba tan poca señal que había que subir tanto el volumen que el ruido de masa era sencillamente inaceptable. Después de intentar ecualizar algo el sonido y de probar con otros cables, lógicamente sin éxito, decidí quitarlo con la intención de devolverlo o directamente tirarlo a la papelera. Al aflojar de nuevo las cuerdas se me ocurrió probar a desplazarlo un poco (apenas 5 mm), deslizándolo hacia fuera. Volví a tensar las cuerdas y la diferencia fue como la noche y el día. Suena bastante bien. En las fotos se ve cómo de "metido" lo he dejado. Si lo metes hasta el fondo se oye como el culo... Lógicamente no es como un previo Fishman instalado en una guitarra de serie pero cumple su función. Por el dinero que cuesta creo que es la mejor alternativa. Sería genial si consiguieran hacerlo con conexión de Jack grande, aunque aumentara algo el tamaño, para no tener que estar usando adaptadores o cables malos, con la pérdida de calidad que eso supone. Muy buen invento.

Funziona e considerando il prezzo è un ottimo acquisto.Sulla mia chitarra, lo spazio tra i pin ed il ponticello era stretto. Per farcelo entrare ho dovuto limare con carta vetro la barretta e nonostante cio ha funzionato perfettamente.

What I like: 1) Ease of installation (just loosen the strings and insert the pickup), 2) Detacheable cables (I received 2 types of cables plus a safety clip to hold the cable-they're great, I can even use my wireless transmitter/receiver), 3) Volume control - it's right there when you want to control the volume, easy and sensitive - excellent feature, 4) Attaching to the amplifier - no problem (I have the positive grid spark 40 & Bose s1 pro), 5) and, most of all - the SOUND QUALITY - GREAT GREAT SOUND (no feedback, no humming or unnecessary noise from the pickup; just pure natural sound - I used this on my red label Yamaha folk/acoustic guitar - it just naturally amplifies the natural sound of my guitar, AND, aesthetically beautiful and compliments the appearance of my guitar as well.What I don't like: None so far that I can think of....

Stopped working 36 days after it was delivered. This KNA pickup model looks good mounted on a guitar and sounds decent for the price when it works., But its no good to me if it stops making sound go to the amp. Certainly would have liked it to function properly much, much longer than just a little over a month. Very disappointed in reliability of this hardware. Only on data point, but not thinking of KNA pickups again.
