The Tube Squealer faithfully recreates not one, not two, but three of the most famous flavors of the most played overdrive pedal of all time. While there are seemingly countless revisions and tributes, the venerable original 808, TS9, and TS10 versions of the circuit have famously been used by iconic guitar players like Stevie Ray Vaughan, John Mayer, Slash, John Frusciante and many more. Like all three original pedals, Tube Squealer delivers that classic amp-driving tone with all the nuance of the different circuits to support all types of playing - from edge of breakup blues, to searing metal solo boosts.
