One minute you are thrashing out chords with a deep, rich distortion, and the next creating a delicate melody rich in reverb and delay, all with the tap of your foot. The Roland GR-55 opens up a huge amount of possibilities for any electric guitarist, no matter what style or genre. The compact, rugged multi-effects pedal contains more than 900 sounds, including all kinds of pianos, synthesizers, and strings. All the on board sounds are PCM, too, which means you can edit them to your liking and save your own presets for use later. If you need to beef up your sound, then the Roland GR-55 contains a huge selection of amplifier models to play with in addition to all the onboard effects. If you need to record that latest riff, then the two USB ports make hooking your GR-55 up to audio software simple, too. There is a vast inventory on eBay that means finding your own unit is straightforward, and there is certainly no harm in looking for some additional, complementary accessories at the same time.
