A classic overdrive circuit with modern modifications for improved performance and versatility. A 100 Hz cut and boost control allows a more focused EQ when cut, or a beefier tone when boosted. A bump switch engages an alternate EQ voicing that boosts the lows and mids. Put it in front of the ‘78 Custom Badass Distortion for a slew of amp-like gain structures that won't mask your tone. True hardwire bypass. Powered by 9 volt battery or AC adaptor (ECB003).
