The Fishman PRO-AG0-UKE passive undersaddle pickup for ukuleles is very good quality, producing a clear tone when amplified. It will work with your amp, but you might want to consider a pre-amp for live performing. This natural tone is a fantastic representation of your ukulele's sound. It operates without interference of alteration of the ukulele's voice, with this simplicity being the key attraction of a Fishman passive ukulele pickup such as this.

The piezo-ceramic ukulele pickup element is 3/32” (2.3mm) wide, to easily slot into your ukulele saddle. The length is 1.67”(42.4mm) from the G to A string. The end of jack input has ridges to allow it to double as strap button. Professional installation is recommended, it involves drilling and soldering - but if you are handy at doing things yourself, Fishman's website has a guide on how to do it, and there are also good resources on Youtube. If at school, it took you three terms in woodwork to make a tent peg, then installing it is probably not for you and a professional should be sought out!

The Fishman PRO-AGO-UKE passive pickup comes is a very smart box, beautifully packaged.... but inside there is not much to see, the pickup element and the jack socket. But what is inside does a really great job, which is the main thing!
