From the post

This is a great sounding drive pedal from Mad Professor. Very dynamic and tube-like, the Sweet Honey is a medium gain overdrive that can produce a wide range of tones, from jazz to heavy rock. I've laid the board out for right angle PCB pots mounted from the solder-side of the board, and it should all fit nicely in a 1590B.
