While a cheap reverb can hurt your recordings, some of the best-loved reverb sounds in history were happy accidents. Electronic Musician has a great article on finding your own distinct reverb sound in the space around you:
… for all its wonders, digital reverb is not indispensable, nor is it always the best way to impart a convincing sense of space to your recordings. Does anyone really think that, for example, Miles Davis’s Kind of Blue would sound better if PCM70s had existed in 1959? Would Led Zeppelin’s “When the Levee Breaks” still hold up today as a zenith of rock drum tones had the kit been close-miked and swathed in digital reverb?
Hot-water heaters, it seems, make great reverb tanks, and a washer or dryer can make a distinctive-sounding reverb chamber.
