The Wampler Pinnacle Deluxe V2 is Eddie Van Halen’s “brown sound” in a pedal. Great for getting high gain crunch out of your guitar. There are a few more additional controls plus an extra footswitch between this and the standard Pinnacle. Controls include: Volume: the overall volume of the pedal. Gain: controls the amount of gain. Treble, Bass, Mids: three band EQ for adjusting your tone Vint./Modern switch: Sets the overall voicing of the pedal’s frequencies. Vintage is darker and modern is brighter. Boost: amount of volume and gain added with the boost switch Boost toggle: adds more gain to the boost Boost footswitch: activates the boost, it runs before the gain stage of the pinnacle. It can also be used on its own Sag: lowers the input gain to reduce low end compression The Wampler Pinnacle Deluxe is true bypass and can be powered by a standard 9 volt DC adaptor with 2.1mm negative center barrel. Current draw is 19 mA (9volt) or 23 mA (18volt).
