Roctron Prophesy

Rocktron ProphesyGuitar Player Magazine wrote that the Prophesy "provides unprecedented depth and flexibility. From a pure processing standpoint, the Prophesy is a tremendously powerful tone-shaping tool."

The depth is truly amazing and the control is top notch. As Guitar Player wrote: "If you’re a player who yearns for extreme real-time control…my prediction is you’ll go nuts over the Prophesy."

- Preamp Section

The preamp section of the Prophesy features four channels each with their own distinct "voicings" to provide a vast array of desired tube amp sounds. Each voicing may be thought of as a "channel" and each channel has it’s own basic gain and master controls with bass, mid, treble and presence controls, all easily accessible with "real amp" knobs on the front panel, just like a regular amp head.

- Channel 1 or Clean American, replicates some of the most sought-after clean vintage tweed amps of the late 50’s and 60’s.
- Channel 2 or "Texas Blues", is a vintage tweed with a bit more "kick" and "bite" often heard from the famous southwest bluesers ala "Billy Gibbons, Stevie Ray, Eric Johnson, Etc.".
- Channel 3 or "Vintage British", is a traditional "Plexi Style" tone offering some of the most dynamic rhythm tone available.
- Channel 4 or "Mega Drive" is considered the Holy Grail of almighty heavy tone of modern music pumping out everything from early Van Halen to Megadeth and everything in between.

The preamp section also features a parametric Pre EQ, which allows you to "pre-shape" your tone to simulate the characteristics of several different guitars (such as fine-tuning your Strat to sound more like a Les Paul, Etc) as well as an additional parametric Post EQ to add extra Lows, High, or scoop out the Mids. And if that’s not enough, we also included a Global Parametric EQ which adjust the overall output of the Prophesy on all presets.

Effects Section

The effects section of the Prophesy is divided up into two sections, Pre distortion (or pre-preamp), and post distortion (or post preamp) for unlimited configurations of effects. The pre-effects section features Wah, Compressor, HUSH(r), Pre-EQ, as well as one assignable effect of your choice. The post-effects section provides ultra-transparent, high-quality effects which completely preserve the tone of the preamp-thick reverbs and lush choruses can be used without coloring the sound of the preamp’s tone. Four assignable "effect blocks" allow you to assign 1 effect pre-preamp and 3 post preamp effects in any order you choose, including Phaser, Flanger, Chorus, Pitch Shift, Rotary Speaker, Ducker Delay, etc. Prophesy also features a versatile mixer section to control the mix between dry and wet signal output of every effect used in the preset.

If the effects in the Prophesy are not enough, we included a true stereo effect loop which may be assigned anywhere in the effect chain just like an internal effect. Want just an incredibly powerful effect processor? Just bypass the preamp section completely and use the Prophesy a stand-alone effect unit.

The ADSR (Attack/Decay/Sustain/Release) function features Rocktron’s Pluck Detection patent-pending, and allows you to configure any of the Prophesy parameters to be controlled dynamically by each pluck of a guitar string. More about the ADSR as Guitar Player Magazine says: "it’s an incredibly musical application that is very different from the usual expression-pedal tricks. You could do some groundbreaking stuff with this killer function!"

Other features include a visual representation of the assigned effects signal chain, preset title, the voicing (channel) being used, are all conveniently displayed on the first preset page. The buttons in the 16 button matrix show the effect status (in or out) as well as allow you to instantly jump to those effects’ parameter pages for instant adjustment.

Of course, the Prophesy maintains the high quality operational features that Rocktron processors are well known for, such as glitch-free preset switching with no signal drop out or lag time and the most natural sounding effects.

Marshall JMP-1

Dave Mustaine previously used Marshall JMP-1 pre-amps.

Designed by a team of guitarists who think exactly as you do, this great sounding, 1 rack space, easy to use and program four channel preamp offers instant recall of your 100 favourite settings. The JMP-1's valve driven heart (2x ECC83) drives pure tone into each of its four uniquely voiced channels - Clean 1, Clean 2, OD1 and OD2:

Clean 1 is perfect for warm full-bodied chords, fat clean lead passages and jazz tones. Clean 2 has the glassy edge of a JTM45 for those bright, jangly tones. OD1 - this channel's smouldering power will take you from the molten gold of a Super Lead Plexi, to searing metal and all points in-between. OD2 - tightly focused, high gain is served up here by the truckload. Modern and aggressive, yet fluid and toneful. This channel has all the distortion and sustain you'll ever need.

Marshall JMP-1 Pre-amps

Each channel includes the following programmable controls; Volume, Gain, Bass, Middle, Treble and Presence, plus a Bass Shift option which re-shapes the low-end character of each channel. Its stereo, Parallel FX loop is also 100% programmable and has level selection, ensuring it is totally compatible with any effects device.

Program recall is instant either from the front panel, via the optional Marshall 4-way footswitch (the MPM4E) or via MIDI. Talking of MIDI, the JMP-1 has MIDI IN, OUT and THRU connections, a mapping facility and MIDI channel selection - ensuring it will fit seamlessly into any rack set-up.

In addition to the standard Left (L) and Right (R) Outputs, the JMP-1 also features L & R Speaker Emulated Outputs, the remarkable realism of which have received much critical praise. This facility not only presents your soundman or engineer with a totally controllable direct stereo signal, it also makes home or studio recording simple.

With a valve MIDI preamp as easy to use and as flexible as the JMP-1, the only limit to your creativity is your own imagination.
