FX42B Bass E.Q.
Two FX42B Bass E.Q. pedals, from early 1988 (left) and late 1988 (with "transition" cosmetics)
The FX42B Bass E.Q. was a seven-band graphic equalizer, based on the FX40B Equalizer but voiced for bass guitar (50-3200 Hz). It was introduced in mid-1987 and produced until about 1996. Later versions used all-plastic slider pots, eliminating the risk of losing a rubber slider cover.
- Controls: sliders (+/- 18 dB) for Level and 50, 100, 200, 400, 800, 1600, and 3200 Hz
- From the manual (shared with the FX40B): "These two effects pedals are graphic equalizers. Each slider boosts or cuts a one octave wide band. Each band is like a tone control which only affects a narrow part of the sound spectrum. The FX42B ... has seven equalizing sliders and one level control slider. When the sliders are moved to change the sound, the pattern made by the slider knobs graphically shows the equalization curve created by the pedal. The graphic equalizer allows you to change the sound or tone of your instrument and effects, lets you get more gain from your P.A. system before feedback, and lets you compensate for inadequacies in your P.A. The level slider lets you adjust the output of the graphic equalizer to make up for the equalization you apply."
