Revalverb is Spring Reverb for studio ( 4 Tubes / 4 Transformers )
In this demo I use a TAD pan 4AB3C1B ( long decay with 4 spring )
- Input hipass ( 700 / 350 /250 / 125 / 90hz cutoff ) that allow to control the frequency send to the spring to rattle
- Output hipass ( 500 / 300 /200 / 100 / 70hz cutoff ) that allow to control the frequency after the spring ( Wet Signal )
- Controls : Dwell / line input / output control / Bias switch + a clean / warm switch for wet signal
- Line In / Line out are transformer balanced ( 10K In / 600R or 150R Output on demand )
