The Maestro Sample/Hold from the early to mid-70s is a classic effect pedal that offers vibrato, tremolo, and rhythms with added patterns. Our Master Sampler & Hodler is a clone of the original that adds modern versatility with three potentiometers and a Reverse Sweep Switch. The Filter mode activates an envelope follower that contours the modified low pass filter’s response curve according to the dynamics of the input. The Sample/Hold position controls the filter’s response randomly, but with an overlying rhythmic element determined by the controllable LFO (Speed control). The controls include Filter Range, Attack, Decay, Resonance, Speed, and two trimmers (T1 and T2) inside the pedal. The Filter Sample/Hold switch switches between Envelope Filter or Sample/Hold modes, and the Reverse Sweep switch reverses the direction of the sweep. The Attack, Filter, and Decay controls work only in Filter mode, while the Resonance control works in both modes. The pedal offers a range of different resonant peaks as the S/H operates.
