Share this:
– For your consideration is this vintage 1973 S. Hawk Ltd. II Tonal Expander graphic equalizer and treble booster effects pedal.
– This excellent all original example is in perfect working order.
– Designed by Harry Kolbe, the Hawk II Tonal Expander is a 3-point peak-and-dip equalizer optimized to complement electric guitar specifically. The designated EQ points are not those traditionally found on HiFi or pro audio equipment, representing a very unique curve best for guitar. Kolbe was wise in his design, using an inductor based EQ schematic, which renders the tonality much more organic, smooth, and natural: in recording, NOTHING beats inductor EQ units. The Hawk II was famously used by Rory Gallagher, and this effect has since been dubbed the “holy grail of boosts.”
– Features: red switch = on/off, middle switch = gain boost, right switch = treble boost. The EQ slider frequency points are: 170Hz, 550Hz, and 2500Hz. 18v battery operated design, 2 x 9v batteries.
– It does not have a bypass switch, and the off button kills signal entirely. Literally on or off.
– All photos are of the actual pedal.
