PreSonic: Medium, Steel-String, 0.125" Saddle

Side-mounted preamps like the Fishman Presys family are everywhere — but they come with familiar frustrations. The tone is often thin and quacky, with uneven strings that never sit right in a mix. Feedback is a constant battle at stage volume, and the limited EQ leaves you stuck shaping your sound around the system instead of around your playing.

The PreSonic is built to change that. As a direct replacement for the Fishman Presys family, it drops into the same cutout and uses your guitar’s existing mounting — no new modifications required. Inside, it’s powered by our saddle-integrated pickup design: six transducers sense each string individually without the static pressure that causes piezo quack, giving you a natural, open response. Each string is adjustable, so your balance is perfect across the neck.

Onboard, a full 3-band EQ with mic blend puts powerful tone-shaping at your fingertips. Whether you need to cut through a dense band mix or add air and depth for a solo performance, PreSonic keeps you in control. And thanks to its differential preamp design, feedback is dramatically reduced, even on loud stages.

Installation is straightforward: everything you need is included in the DIY kit, and with just basic tools you can upgrade your guitar in a single afternoon.
