The Avalon 737 Vst is just like the actual Avalon VT737SP which features a combination of TUBE preamplifiers, opto-compressor, sweep EQ, output level, and VU metering. The vst is just like the real verison except for the fact that it is computerized, but it still doesn't make much a difference sound wise. This vst can be used for almost anything! Mixing instruments, mastering a full track, enhancing vocals, bringing warmth to your mix without saturation, etc! We've heard a lot of expensive vsts in the market and this vst does not differ much from them sound wise. This vst still continues to surprise people especially because of its unbeatable price!
