Built with a two-band EQ, mix control, and frequency orientation firmly seated in the lows for the four-string crowd, the Ibanez TS9B Tube Screamer Bass take the beloved mid-gain crunch of the original and translates it for bassists. A versatile bass effect, playing around with the five-knob interface for even a few minutes will yield tones ranging from a vintage-voiced overdrive to a nuanced fuzz with just the right amount of bite.
