The JHS Clover is a FET preamp and boost based on the BOSS FA-1 from 1984, with more EQ and an XLR output added. A rotary switch picks Full EQ, with Bass, Mids and Treble all working; No Mid, an exact replica of the FA-1 with the mids fixed; or No EQ, a straight FET boost for pushing an amp.
Volume sets unity or boost, and a Low Cut dip switch on the side trims muddy lows. The XLR output carries the same signal as the 1/4" output, for acoustic and bass players feeding a desk or interface, with a ground lift for hum. With up to +24dB of gain, its best work on electric is pushing a tube amp into its own overdrive: single coils pick up punch and depth, humbuckers pick up clarity and bite.
The Haunting Mids works on one band; the Clover is the full three-band preamp.
