Pivy RMast Deep Image Pack for NUX MG-50

Pivy RMast is a tone pack inspired by the Peavey Rock Master preamp pedal, capturing the versatile drive and distinct character of the original unit. This pack is built on Choptones Deep Images, our captures of the original pedal for the NUX MG-50, paired with Choptones Custom IRs, so you get the genuine voice and feel of the real unit on your device.

How It Sounds

The normal channel offers a balanced response ranging from clean tones to moderate breakup that responds well to picking dynamics. The hi gain channel pushes into dense, saturated distortion with a tight low end and strong midrange presence, suitable for heavy rhythm work and sustained lead lines.

Each preset went through multiple sessions on the actual unit, adjusting mic positions and cab pairings, listening for the difference between a setting that sounds impressive in isolation and one that actually works in a mix. They all sound like the same unit, just from different angles.

What's in the Pack

The Deep Images cover the normal and hi gain channels of the pedal. The IRs were captured with Marshall 1960 4x12 cabinets loaded with Celestion V30 and Electrovoice EV12 Black Label speakers, a Bogner 4x12 with Eminence DV77, a Mesa Roadking 4x12 with Celestion V30, a Friedman 4x12 with Celestion G12M, and a Peavey 4x12 with Celestion V30 and T75 speakers, chosen per preset based on what each tone needed.

This pack is made for the NUX MG-50.

10 ready-to-play presets, built on 2 Choptones Deep Images and shaped with 6 Choptones Custom IRs. Load the Deep Images and the IRs on your device, then recall the presets.

Remember to set the gain and general volume knobs at your liking, according to your guitar and pick ups!
