Rock Master® Preamp Pedal

$199.99

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.

FAQ

Practically identical. The Rock Master Preamp Pedal is equipped with the same TransTube technology that gave the '90s preamp its punchy, tube-like response. The gain and EQ architecture remains true to the original Rock Master amp's "Ultra" channel.

Yes, the Rock Master Preamp Pedal is essentially an "amp in a box" pedal. This means it offers everything that an amplifier's preamp section would, including gain controls and EQ for tone shaping.

Yes, the Rock Master Preamp Pedal will work with any guitar combo amp or amp head. If your amp has an FX loop, connect the preamp pedal to the input or return for the FX loop to completely bypass the preamp section. You can also plug straight in to the guitar input: set the amp's gain to a clean tone and leave the amp's EQ controls neutral for best results.

No. The Rock Master Preamp Pedal is intended to be used to supercharge the front end of your amplifier, plug into a power amp with speakers, or connect to a speaker emulator. You can also record the output of the preamp pedal and apply IR speaker emulation in your DAW.

Yes, you can use the Rock Master Preamp Pedal to replace a traditional amplifier in performance and recording situations. Keep in mind that you will want to apply speaker emulation in your signal chain for realistic amp tones.

Very well. Power is stepped up to 30 volts internally for high-headroom dynamics, giving you the range you need for punchy clean tones. Adding gain delivers the tenacious and saturated sound of the classic Ultra channel. A Gain footswitch makes it easy to switch between cleaner rhythm tones and searing lead tones.
