Fishman Powerjack PRO-PJA-001 Installation

Both the manufacturer’s and our recommendation is always have a qualified stringed instrument tech or luthier perform preamp installations. Nonetheless, we recognize that lots of players out there work on their guitars and ukuleles and are capable of performing this installation. If you are adept with a hand drill, can follow instructions, and carefully consider the mechanical factors that can affect performance, there’s no reason why you can’t successfully install this preamp in your guitar or ukulele.

Please note that Fishman’s instructions, are tailored for installations on steel string guitars. Apply the principles outlined in their installation guide as they would pertain to a classical guitar or ukulele.
