2000s Vox Cooltron Bulldog Distortion Tube-Driven Guitar Effects Pedal

$114.99

+ shipping

Up for sale, a Vox Cooltron Bulldog Distortion effects pedal in excellent condition and in perfect working order. Made in Japan and introduced in 2005, the discontinued Cooltron Bulldog Distortion offers growling tube tone via a single 12AU7 tube with extra bite to your fret burning maneuvers. Two channels are provided, each with its own Gain and Volume controls. Gain 1 dishes out vintage-voiced distortion while Gain 2 packs a more modern, aggressive sound with slightly scooped mids. Both are adjustable from subtle to completely over the top. A Bass control adds extra low end fullness at extreme settings, and a warm, round, mellowness at lower settings. And with the Gain 2 Voice control you can independently tailor the second channel's hell-raising tone. The Treble control offers biting attack at one extreme and smooth, fluid sweetness at the other. The Bulldog is also equipped with true bypass functionality, preserving the integrity of your signal when not engaged.

The Cooltron circuit operates by using two very special signal paths. The first is the "servo circuit," which provides the right conditions between the plate of the tube and the grid. This achieves controllable, stable parameters for the tube and provides the correct operating conditions for the tube to function as it would if run at a higher voltage. The second circuit is a patented power supply that provides a low voltage, low current supply to the heater elements in the tube. Since the tube is now running at such a reduced supply level, the anode current is much smaller than normal. This means that the amount of heat required at the cathode to achieve sufficient cathode current emission is much less, hence the ability to run the heaters at a lower level and for Cooltron pedals to run for 20 hours on 4 x AA batteries. Standard 9v adapter operation is also available (not included).

Cosmetic wear is limited to faint surface patina on the sturdy chrome-plated enclosure, while the graphics are pristine. The original set of knobs are intact, as well as the rubber feet and foil label on the bottom.
