"Alesis 3630 is best buy for HOUSE MUSIC PRODUCERS"
overall, this is probably the best sounding dynamics processor you can own without spending upwards of $1000
Punchy, tight sound. Probably bad for rock music or a live band. GREAT for house music, techno. Used by Thomas Bangalter of Daft Punk, Patrick Alavi, High Caliber and many other house music groups.
all the necessary knobs that you would need in a dynamics processing unit.
mine is beat up, but the sound it clean
this is the best compressor for the money
