The Rooster is a vintage style Treble Booster built from the greatest parts available including tropical fish capacitors and carbon comp resistors.  JAM Pedals sought out the best, and extremely rare, CV7003 military spec OC44 germanium transistor for its constancy and heat tolerance.  

Each transistor is measured for gain and leakage then matched by sound auditions.  The top-mounted toggle switch let's you select bass, treble or mid boost.  This is the pedal for Bluesbreakers era Clapton as well as Rory Gallagher, Brian May and Tony Iommi tone.

The Rooster has a positive ground.  If powered with a chained power supply a positive ground adapter must be used (not included).        

- True bypass

- Can run on a 9-volt battery or a 9-volt, positive ground, DC power supply (not included)

- Limited Lifetime warranty

- Point-to-point wiring available.
