Fits very easily and well to a guitar with a Tunomatic bridge (I used a Jackson Rhoads). Floyd bridge guitars will require sufficient space between the bridge and the pickup and necessitate using the 'mild' adhesive to attach the pickup to the guitar itself. The wireless functionality is great - no noticeable latency and battery life is excellent. The stock / default sounds are wonderful and I could made very good use of the strings, wind, sax, flute type instruments but I found that piano/keys and and other 'high attack' type instruments such as nylon stringed guitar suffered terribly from ghost / artifact notes and were practically unusable even where playing extremely cleanly. Perhaps a factory fitted Tripleplay might improve on this (such as the Godin or Fender Tripleplay equipped guitars that are available).
Unfortunately, the real problem that I found was with the software. Even forgetting the time consuming and impenetrable 3rd party software components provided on a 'trial' basis (but still require registration and authorisation), the base FTP installation was incredibly unstable, at least in Windows 7, and would crash completely seemingly at random. The software interfaces are also quite terrible. Native instruments and Fishman should be ashamed of themselves for producing such user unfriendly interfaces.
I could have lived these shortcomings with that had the software been more stable. Unfortunately the instability of the base FTP software made the whole package utterly useless for live performances and there was no way I could rely on it for fleshing out the sound of a covers band.
