| Vox Cooltron CT06TR VibraVOX Tube Tremolo/Vibrato Pedal
With today's heavy effects pedal market this little guy unfortunately gets overlooked, but we're hoping to change that because we fell in love with it! This pedal produces tremolo and vibrato as nice and warm as most any you've heard built into an amp! You can select between 2 tremolo channels, a vibrato and a tremolo, or 2 vibrato settings....and each of the channels have independent speed control. The VibraVox uses a 12AU7 tube which delivers warm, rich tone. There is also automatic ramping which adds Leslie-esque sounds!
The VibraVox faithfully reproduces the Tremolo and Vibrato from their legendary AC-30 amplifier.

Want to know how it all works?
Normally, tubes are used at high voltages and this restricts their use in battery-powered devices such as guitar effects pedals. Historically, attempts have been made to use tubes at low voltages in what has been dubbed starvation" mode, but these circuits don't allow the tube to function in an acceptable manner. The tube simply cannot be biased to a satisfactory operating condition. Plus, the necessary heater (filament) current is too high to deliver acceptable battery life. Imagine how annoying it would be to have to change batteries every ten minutes during a gig!
Here's what makes the COOLTRON system tick. The COOLTRON circuit basically 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 smaller hence the ability to run the heaters at a lower level and for COOLTRON guitar pedals to run for 16 hours on 4 x AA batteries!
The COOLTRON system provides true tube sonic performance at very low voltage and at reduced heater current ideal for inclusion into the COOLTRON VibraVOX pedal.
