Want the warm sound of tubes in the rack? The HHB Radius 20 is a 4 band 2 channel tube Parametric EQ that has a really nice sound. Many like myself convert it to a 8 band EQ by simply running channel one into channel two. I've been running the Behringer Deq 2496 as a EQ for many years until switching over to this unit and to my ears the Radius 20 has a much warmer less digital sound you would expect with a tube EQ.

This unit has been modified by replacing the OP amps to higher quality TLE2074s and OPA604s. The 12ax7 tubes were replaced with the RCA 5751 Command tubes new old stock from 1962 for a warmer sound.
