Kush Audio has released REDDI, a Tube D.I. Plugin for Mac OS X and Windows.
Here's what they say:
The original hardware REDDI is a legend among professional session players and commercial studio owners. Its hybrid tube/solid state gain circuits, beefy transformer, and oversized power supply have an uncanny ability to both reign in bass transients and punch them up. Without any eq – simply through its gentle tube shimmer – REDDI gets bass, synths, and guitars to 'sit' in the mix with less processing and fuss.
The REDDI plugin, then, is designed to be used as any analog DI would: first in the chain, as an initial treatment before compression, saturation or eq – imparting its unique tube sweetness to any instrument in your mix.
Price: $49 (or monthly subscription for all Kush plug-ins - $9.99).
