Optical compressors are known for their smooth attack and silent operation. The Celeritas is no exception. Great, musical compressor and for some even an 'always on' effect.
I highly recommend combining the Celeritas with the Hyperdrive so you can switch between 9V and 18V modes.
The B-stock version needs one simple connection added underneath the board with a piece of wire or 0R resistor.
