Up for sale is the rare Monster Effect El Dorado Overdrive pedal. Built by the creator of the Mastortion and Swamp Thang tremolo. This is a very early version Serial# 004 and not very many of these were made. The pin striping is gorgeous and in beautiful condition. NOTE: When I was talking the screws off the back plate to change the battery, two of the screw heads broke off (see picture). Dont know why he used pot metal screws but it is what it is. That is the only issue with the pedal and does not affect the sound at all. Please ask all questions and thanks for looking. Found this review in the Musictoyz forum that really captures the vibe of this pedal: "Nails the old Billy Gibbons tone ive been after...A rare thing these days but it excels at low AND high gain. High gain being ZZtop circa 1974 full out lead tone not high gain metal. This is not a TS or a Disto box its a serious tone box, Very open, natural uncompressed gaintone witha fuzz edge."
