About This Listing

The MGP-1A is an all-tube, all-analog modeling preamplifier featuring 18 pristine models of the best guitar amplifiers in history. At the MGP-1A's core lies our patented VEnuM™ modeling engine. When a model is selected, VEnuM™ rewires the nearly the entire tube signal path down to the tone stack to accurately capture the breakup, harmonics, gain and filtering that make the originals sound the way they do. The feel and response change with the settings you apply and the way you play, just like you were playing through the real thing.

Each of the 18 models has a host of tone shaping features like Bright and Deep controls to alter the treble and bass voicings, two unique tone stacks per model, and an EQ shift to re-voice the active tone stack. These extra controls both model tone shaping features found on the originals or help mimic the tone of amplifiers closely related to the active model.

The MGP-1A is designed to be extremely easy to use with dedicated controls for every function. It has also been designed to be versatile. Being a preamp, it can slide into any setup and work with the gear you already own.

The MGP-1A features extremely low-noise power supplies and low-noise tube circuitry for studios and recording. For the stage, the MGP-1A is MIDI equipped with the ability to store and recall up to 128 presets via your existing MIDI controller. For those without a MIDI enabled rig, the included FS-3 footswitch takes care of your channel switching needs.
