Boss RV-3 Reverb/Delay - This RV-3 is a great all around reverb and delay unit with a ton of options to suit most styles. 11 modes offer various modes of standard delay, delay plus reverb, and straight reverb. Up to 2 seconds of delay and four useful types of reverb (Room 1, Room 2, Hall, and Plate) are fully tweakable. Like most Boss delays, the repeats are crisp & pronounced with a dependable decay. All four reverbs bordered a little on the bright side and we constantly found ourselves rolling a bit of high-end off with the tone knob just to keep things warm. It’s not shrill in any sort of way, we just happen to like our reverb a little darker sounding. The Reverb/Delay combination modes knocked the delay time down to around 1 second but created a thick and washy spaciousness that should send most ambient types and space rockers into the stratosphere.
