1 Mark Nason 2 years ago Thinking about freshening up my pedalboard. Time to try new flavors (hopefully some more Nocturne creations). Voodoo Labs Tremolo: 4 knob version. Excellent Condition w/original box & paperwork. $95 Monster Effects El Dorado: Long since discontinued, hand wired number from John Spears. Medium gain pedal (lower gain precursor to the Mastortion). Great ZZ Top-ish Tweedish OD sounds. Hand pinstriped top. A few nicks in finish (nothing major). $125 Both pedals can be seen here on my pedalboard.
