Independent shopping perspective
AH Booster is a compact overdrive pedal with three compression voices and active bass/treble EQ. Normal keeps the response balanced and dynamic; Tight emphasizes pick attack with a focused low end; Smooth brings maximum sustain for lead work. The EQ provides up to 15dB of cut or boost in each range, so it can be adjusted around a particular guitar and amp. It runs at 9V or 18V, with the higher-voltage option providing more headroom and a tighter low end.
