Description

The Peavey Rock Master preamp pedal delivers the highly sought-after Ultra Gain tones of the early 90’s Rock Master Guitar Tube Preamp in a compact package small enough to fit in your back pocket. The pedal is now available worldwide through local and online retailers. The original Rock Master Guitar Tube Preamp is what some consider to be the granddaddy of what became the Peavey XXX and JSX guitar amplifiers. Most notably, the Ultra gain section. The new Rock Master preamp pedal focuses on this Ultra Gain section and the units Voicing EQ. The units PRE and POST gain controls allow the user to control the amount of gain applied to the input signal via the PRE control and the overall output volume via the POST control. The active three band EQ/Voicing section allows players to fine tune their overall tone with BOTTOM, BODY, and EDGE controls. As it implies, the BOTTOM control is an active +/- 15dB shelving type tone control that varies the low frequency boost or cut. The BODY control is an active, peak/notch +/- 15dB tone control that varies the mid frequency boost or cut. And the EDGE is an active +/- shelving type control varying the high frequency boost and cut. Internally, it is Peavey’s TransTube technology that brings it all together to create that groundbreaking Peavey Rock Master “Ultra” channel circuit. Construction of the pedal uses a die-cast metal enclosure, fiberglass PCBs with 2-ounce copper and plated through holes on all components, high quality pots, switches, and jacks, and cosmetics reflecting the original preamp that influenced a whole generation of guitar amplifiers. The pedal can be used with either a 9v power supply or battery.

Why We Like This

The separate mid shift and gain switch make it easy to move beyond one fixed high-gain voice. Post Gain keeps that sound change manageable at the next input.

FAQs

Q: Can I change the midrange control’s frequency?
A: Yes. The Shift or Mid Shift switch selects a higher or lower operating frequency for the Body control.

Q: Can I use any power adapter that fits?
A: Match the required voltage, current, polarity, and connector. A physically fitting plug is not enough.

Q: Does it replace a speaker cabinet?
A: A signal-processing pedal does not itself produce room sound; route its output to suitable amplification or recording equipment.
