BOSS TU-3S with PigHog 9V Power Adapter

BOSS TU-3S Chromatic Tuner provides the same function, accuracy, and display, as the TU-3 – a go-to stompbox tuner for many electric guitarists. However, this model doesn’t sport a muting footswitch; it’s always on. This feature, in addition to its small size, renders it suitable for integration in any pedalboard or stompbox rig in which space-saving is paramount.

Pig Power is a 9V power supply with 1000 mA can power up to 10 pedals at once (PP10DC 10 Spot Daisy Chain not included), with a minimal design that requires just a single outlet. The positive sleeve/negative tip works with most effects pedals on the market, including Boss PSA or ACA, Danelectro DA-1, DOD PS-200R, Dunlop ECB-03, Ibanez AC-109, Korg A30950, Morley 9V, Zoom AD-0006, and more! The power adapter is backed by a one year limited warranty.
