Pickup KNA Bouzouki BZ-1A Active

Pickup arrived promptly, well packaged and with clear simple instructions. Included was a little tool to tighten the barrels on the attached good quality "carpenter style" jack socket. The barrels were long enough to fit my viola, though I wonder if they might struggle with a very large instrument? The kna website suggests the pickup ships with spare longer barrels for such an instrument? As a precaution, I loosened the top two strings to avoid any distortion in shape of the bridge and set too with emery boards (used to file finger nails.) In no time at all, I had a snug fit for the piezo element. (See the photo) First impressions: plugged into a 1M ohm instrument input- a balanced, warm sound with lots of signal (more than I was expecting). Eventually, I boosted the presence and cut a little of the lows to closer resemble the acoustic sound of my viola. Not that you'll need to if using say, a smaller guitar amp. 😁 After a good long play, I was impressed by the usability of the sound - NO buzz, distortion, or hum. Maybe use a hi-pass filter to minimise handling noise if going into a large pa? As someone who's used amplified strings many years- my violin has the (industry standard) L.R. Baggs fitted - I'm VERY impressed, especially considering the price!

You may have to file your bridge down to accommodate the pick up. Sound is pretty good, especially for the price.

Superb pic up for my 200 year old cello. Easily fitted, and stable once in place. Perfect for when I’m playing in public, plugging it directly into my Bose amp…no need for any additional pedals. Sound is far better than the much more expensive pic ups I’ve tried in the past. Thank you.

surprisingly good for a purely passive pickup, works great with my thomann 3/4 bass.

Installed the pickup within 5 minutes of it arriving at my door. Extremely straight forward process. My Romanian 3/4 size double bass needed just two of the extra shims to fit snuggly in the left wing of the bridge. The jack input attaches to the ailpiece very effectively as well. The sound is just what I expected for the price and can really shine with the correct preamp and speaker. I’m very happy that it can easily be removed and is not too obvious.

Easy to fit, you have to slacken the strings right off to get it under the ties. I ditched the supplied lead, it's cheap quality and not suitable for the job. I replaced it with a 12" long quality 3.5 to 6.35 jack socket lead and gaffer taped it to the body of the uke. I also cut a piece of cork to fit snugly under the body of the pickup - this seems to eliminate the possibility of it snapping off by accident. If you keep the lead of out of the way it doesn't make interfering noises. I've plugged it into my Vox Valvetronix amp and I'm well pleased with the sound quality. A great (and cheap) way to amp up your uke. I dropped a star because of the cheapo supplied lead. *postcript* Second photo is Mk2 with a more permanent fixture for the ¼ " socket made from a tin can lid and leather.

It's about as good as a cheap stick-on transduced mic i.e. pretty poor. Muffled toneless distorted response. Fitting it doesn't alter the bridge height as some have claimed. The lead that came with mine faulty too, but luckily I had a spare. I've now taken it off and fitted a proper under-the-saddle piezo pick-up. KNA consigned to the drawer of "looked like a good idea gadgets."

The sound from this pickup is remarkably good. I’ve gigged with it playing through a tonedexter wavemap/preamp into house PA systems where it sounds good and quite acoustic violinish I’m told though part of that is down to the tonedexter. Into an LR Baggs di it’s ok. No tendency to feedback. It does need careful fitting to the bridge. So pleased I bought 2 more, one for my viola and one for my second fiddle.

Buzzing sound and low output

Très bon produit son très clair seul défaut creuser le manche pour installer le micro au bon emplacement et dévisser tout l'ensemble quand on veut changer les piles

Dommage que on peux pas mettre zéro étoiles . Le piezo est très fragile , et mal fabriqué le bois est très fin et de mauvaise qualité . Je l’ai mis un fois dans la housse et c’est déjà cassé. Ça peut être dépanner si on garde la guitare à la maison. Mais pour le live pas possible . Évitez de l’acheter …. Argent jeté dans la pouvelle.

No es optima para mi instrumento (oud), pero la pastilla funciona muy bien. Muy recomendable para guitarra clásica

I have a 50yr old Yamaha acoustic guitar. This pickup captures the sound of the guitar very well. Nice option for not cutting into the guitar for an on board pick up .
