PARAMETRIC EQUALIZER — every classic graphic has one catch: the filter centers are stuck on fixed frequencies. A parametric stage gives you the freedom to park the bell exactly where the instrument, cab, or room needs it — not where the silkscreen says you should. Beyond “normal” tone shaping, it’s a serious problem-solver on a busy pedalboard: notch out problem frequencies that ring into feedback boost pick or finger attack on a frequency tuned to your guitar or bass tame a boomy 4x12 or hollow stage resonance carve mids so your part doesn’t stack on top of the bass — better separation in the band without turning up and fighting for volume Extra LOW and PRESENCE controls set the overall weight and air outside the parametric band so you can fix shelf-wide bloom or sparkle without fighting the mid sweep. true bypass premium, name-brand parts power: 9V DC 50mA, standard 5.5/2.1 jack (center-negative) solid metal enclosure dimensions 120mm x 100mm (+ approx. 3mm for jacks)
