Henretta Moody Blue Reverb

They say:

Slightly larger than the original no-knobber line, but sporting top-mounted jacks for ultimate space savings, the MOODY BLUE reverb pedal provides a wide range of reverb sounds with three internal trimmers - dry mix, wet mix, and decay time. You can dial in snappy slapback-esque sounds, amp-like spring reverb sounds, cavernous hall sounds, and all-out ambient bliss.
