Intended for acoustic guitar, bass, or any other acoustic instrument with a pickup and a 1/4" output, the Fishman Platinum Stage EQ is a belt-mountable preamp and DI boasting an analog signal path and tone-shaping options. Connections are possible via 1/4" input and 1/4" output jacks, though there’s also an XLR DI for feeding audio straight to the house’s PA, mixer, or a recording interface. This output is pre-/post-EQ switchable, meaning you can route a tonally shaped or unprocessed signal through this section of the preamp. It can also provide 48V phantom power to the unit.
The preamp itself utilizes a high-headroom Class-A design, with a four-band EQ section that can be voiced separately, by means of a switch, for bass and guitar. A phase switch aids you in the never-ending battle against feedback in live scenarios. To add a little more volume for solos or other stand-out sections, a boost button has been provided, its level of gain adjustable by means of a wheel located next to the button. Simply depress this button to engage the boost. You’ll also find an input trim pot to better attenuate your pickups to the signal path provided by the Platinum Stage. It comes with a belt clip for easy on-stage attachment to your person. In addition to drawing upon 48V phantom power, the unit can run using a 9V battery, or with an optional power supply.

Switchable EQ Modes
Bass: A boost here will add depth and weight to the sound of an instrument with light bass response. Cut the bass a few dB to tighten up the boomy tone of a dreadnought or jumbo guitar.
Middle: Two controls (level and frequency) make up this EQ circuit. The frequency control lets you tune in on a specific midrange frequency range which you can boost or cut.
Treble: This knob will help you cut through the mix, or conversely, mellow and subdue an already shrill tone.
