New Software Lets You Wire Up Custom Amps

RevalverWinter NAMM Show: Peavey introduced ReValver Mk III, a 64-bit amplifier modeling app that

Peavey ReValver Mk III models 15 of the world’s most popular guitar amplifiers, including several Peavey amps, through an exclusive algorithm that analyzes the interactions of the components on the circuit level, based on the amps’ original schematics.

Because it models amps at the circuit level, it even lets you rewire the amps to create your own custom designs.

“ReValver brings a unique approach to modeling software because it essentially lets players design their own amplifiers,” said Hartley Peavey, Founder and CEO of Peavey Electronics, which acquired Alien Connections and ReValver in 2007. “In that sense, ReValver complements the vision of the groundbreaking online Peavey Custom Shop. The implications this technology will have on the future of the music-products industry are vast.”

Unlocking ReValver’s customization tools is also easy. By right-clicking on an amp model, users can “go inside” and adjust the amp’s tones and components on the Tweak Module GUI. This allows users to change, add or subtract tubes on all amplifier models, and then calibrate even the voltage parameters of those tubes. In all, users can program more than 15 features on each tube stage, with as many as 17 preamp and power tube types to choose from.

ReValver Mk III also features a stomp-box and effects section including various types of chorus, distortion, wah, tremolo, compression, limiter, delay, octaver and much more. A new FFT-based convolution reverb allows for very complex and smooth reverbs, including sampled spring reverb, and allows users to import their own .WAV samples. Models of Peavey 6505, JSX, Classic, ValveKing and Triple XXX guitar amps are available in ReValver in software format.

Peavey ReValver Mk III will be available from authorized Peavey retailers in Q1 2008.
