Product Highlights
  • 34 Amp Models
  • 56 Effects
  • Triple-Assignable Pedal
  • 70 Factory Presets
  • USB Recording
  • 60 Drum Resets
  • Integrated Chromatic Tuner
  • Includes Cubase LE4

The Digitech RP355 Guitar Modeling Processor Pedal is a comprehensive guitar workstation that features advanced modeling capabilities and a massive effects library modeled on some of the most popular effects in recorded music's history coupled with 2 x 2 USB streaming to connect with the included Cubase LE4 software for home recording.

The RP355 starts by modeling 34 classic amps and 18 cabinets that you can mix and match. An extensive library of 56 effects can be applied individually, or as part of one of 30 preset effects chains. Up to 11 effects can run simultaneously while three effect parameters can be applied to the expression pedal, for combined effect shifts that are truly innovative.

The USB connection can be used for computer editing of presets. But it can also be used for audio streaming (two streams up, two streams down), making the RP355 an excellent choice for direct computer recording with the Cubase LE4 software (included).

An integrated drum machine with 60 preset rhythm patterns and a chromatic tuner take a lot of the chore out of practicing. The extensive inputs and outputs, switchable modeling (you can turn it off for live play through an amp), and high-resolution 24-bit sound make the RP355 a comprehensive guitar workstation that travels easily between practice, rehearsal, recording, and performance.

Amp Models
Thirty four (34) amps and eighteen (18) cabinets are modeled in 24-bit sound. Digitech's Component Modeling gives a more dynamic, responsive depiction of an amp's performance than amp modeling alone
Tons of Effects
An elaborate set of 56 effects cover the gamut of what a guitarist could possibly need. You can tweak them by hand, or apply them as one of 30 effect chain presets that help you get the most out of combined effects
Triple-Assignable Expression Pedal
The RP355's expression pedal can be loaded with up to three effect parameters. Almost every parameter is available to be assigned. You could, as one example, increase the reverb, chorus depth, and distortion as you depress the pedal
70/70 Presets
The 70 factory presets are matched by 70 user memory locations, so you can save your own creations without losing the excellent preset sounds
Intuitive Operation
The Amp Model, Effect Chain, Effect Level, and Master Level knobs are lined up to function as a simple four-step process for getting stellar tones quickly
USB Recording, Editing, Streaming
The USB connection in the back is not just for computer editing of presets. It also facilitates 2-way audio streaming (2 streams up, 2 streams down), making the RP355 an excellent all-in-one interface for direct computer recording
60 Drum Presets
The integrated drum machine offers 60 preset rhythm patterns for practice purposes, but don't be surprised if they inspire some new ideas as well

      Comments about DigiTech RP355 Guitar Modeling Processor Pedal:

      I use my RP355 for playing gigs in clubs, at outdoor venues and at social functions. It's functionality is mind-boggling. There are so many choices of voices for my guitar, all you have to do is listen to the music you'd like to emulate, and dial it up on the RS355.
      The ability to customize the sound with all the amps and effects known to modern science is unbelievable.

      Particularly useful is the Amp A / Amp B option that allows me to switch from rhythm to a different, usually a little louder, lead voice.

      A problem is accidentally hitting the wrong button in the middle of a song. It's not intuitive how to get back to the sound I was using. Maybe there could be an "Undo" button. Or maybe a "lock" function, to avoid accidental changes.
