The DigiTech RP350 is a modeling guitar multi-effect processor, a floor unit that puts amp models and effects in one pedalboard-style box. DigiTech describes it as covering "guitar tones from jazz, blues and rock to full out metal," and the unit runs on 24-bit high performance audio conversion1. It is no longer made: DigiTech lists it among past products that are no longer in production, though they may still be available through local and online retailers1.
Presets and controls
The RP350 holds presets in two banks: 70 user presets (U1 to U70) that a player can overwrite, and 70 factory presets (F1 to F70)1. For immediate control, Guitar World's 2007 review highlights two additional knobs that give immediate control over amplifier gain and level, so gain and volume can be adjusted without diving into menus2.
The built-in footpedal does more than sweep effects. Guitar World notes it "functions as an amp A/B footswitch for the selected preset," which means two amps per preset2.
Outputs and recording
The back panel carries a pair of direct injection-friendly XLR outputs, which Guitar World says enhances both performing and recording options2. For recording at a computer, the unit ships with Cubase LE4 music production software for arranging, recording and producing music on PC or Mac1.
Power
DigiTech specifies the PS0913B power supply for the RP3501.
The RP350 is discontinued. DigiTech says past products may still be available through local and online retailers1.
Where it sits in the RP range
The RP350 belongs to DigiTech's long-running RP line of multi-effects pedals. Later floor processors in the family include the DigiTech RP360 and RP360 XP, announced in 2014, and other models such as the RP55, RP150, RP250, RP255 and RP500 sit alongside it in the range.
