Digitech produces great-sounding effects with high-speed internal processing. The Digitech RP-series multi-effects processors are among the best value, offering a host of great tones at an affordable price. The Digitech RP90 is a great entry-point for getting into effects as it includes 100 presets and has an expression pedal. Each Digitech effects box above the RP90 in the RP-series, including the RP255, RP355 and RP500, features a metal casing for stage and road durability, as well as increased functionality and greater ease of use. With each step up in the Digitech RP line, added pedals allow for quicker access to tones during performance. Digitech is also known for their JamMan series phrase loopers, which feature an easy-to-use interface and SD-based memory card for storing or swapping up to 99 phrases at a time!
