The Rodenberg Gas-808B NG Overdrive Bass Pedal is designed for bass guitar use featuring Drive, Tone and Level controls. The Gas-808B NG sounds like part of an amplifier itself rather than a pedal. In the special 909B Mode, you can obtain three times more gain than you would with standard overdrive pedals, whilst the deep boost pushes the lower frequencies with the overall sound staying defined without getting muddy. The Gas-808B NG is ideal for boosting your amplifier without losing or affecting its basic characteristics.
