Forget about vintage Tube Screamers*! This all-analog design by pedal guru Bob Weil of Visual Sound and Joe Naylor delivers incredibly natural tube-sounding overdrive, with a wider gain range and perfectly voiced treble and bass controls. Goes from a bluesy boost up to full crunch and singing sustain, without masking the character of your guitar or amp. Also works as an amazing bass overdrive! Features drive, volume, treble, bass, buffered pure bypass, auxiliary power jack, hand-wired jacks, and JRC4558 IC chip. Jacks, controls and switches are directly mounted to a heavy steel chassis for maximum durability.
