Cooltron
The Cooltron series of pedals was created by Vox, a company that began back in 1957. 
They produced only guitar amps at that point, but today, they now have many different lines of amps and pedals. The Cooltron effects pedals all feature 12AU7 preamp tubes that operate at a low voltage. The Cooltron pedals are some of the only pedals to make use of this type of tube since it is very difficult to use tubes in battery-powered pedals. However, the seven different Cooltron pedals all not only do this but they also add incredible sound and tone to your instruments.
The Cooltron pedals achieve this by using special circuits that use two special signal paths. The first creates the conditions for the tube to work. The second is the main power supply that constantly provides a low voltage power to the tube’s heater elements. This allows it to operate on a much lower power level. It doesn’t generate nearly as much heat as a full amp would, which is why it can be done in a pedal. Because of this lower power usage, each Cooltron pedal can run for 16 hours on just 4 AA batteries.
The seven Cooltron pedals:
The Bulldog Distortion pedal features gain and volume controls. Gain 1 provides great vintage distortion, while the second gain channel gives you a more modern type of sound.
The Brit Boost adds some amazing treble and upper middle frequency boost, although it also features a full range boost that pumps up the low and bottom end as well.
Want a warm tone with some great dynamics? Then you might want the Big Ben Overdrive pedal. Its gain control gives you options from blues to full, saturated tone.
The Over the Top Boost gives you everything from smooth to extreme treble control. It also helps with the bass, allowing you to add low-end girth or warmer, smoother tones.
For a smooth, silky tone, the Snake Charmer Compressor has several great features, including the gain reduction indicator that shows you the results of the pedal’s settings. It also has a high/low switch and other controls.
Then there’s the VibraVOX pedal, which basically gives you all the sounds and effects of a standard 30 watt amp, only in pedal form. It’s quite flexible, too, and gives you all the control you could ever want.
Finally, the Duel Overdrive pedal has two overdrive circuits that are similar to the Big Ben Overdrive. This gives you two amazing sounds, one classic, one modern. Both channels are completely independent, too.

VOX CT03BT Cooltron Brit Boost Pedal |
|
Tonal muscle on command! It's both a treble boost and a full-range boost. The treble boost pumps treble and upper mid frequencies like a vintage Treble Boost pedal. In full-range mode it enhances all frequencies and is a great way to kick a slightly overdriven amp into heavy drive. A gain knob varies the overall gain from mellow to full rip and a tone knob lets you tweak the EQ. Features a true bypass for unaltered tone when not activated.

A gain knob varies the overall gain of the pedal from mellow and warm to grinding and ripping! Plus, a Tone knob adjusts the overall tonality of the pedal.

Vox Snake Charmer Compressor Tube Effects Pedal List Price: $300.00 |

Tame your tone with the new Snake Charmer Compressor. The result? Silky smooth, mesmerizing tone that behaves as it should. The Snake Charmer's compression affects the ratio and threshold of the signal, smoothing out peaks and spikes. At the same time, the Snake Charmer also increases the Gain level to complement the corresponding ratio and threshold settings so that the overall gain remains constant. There's also a Gain Reduction Indicator that gives you visual cues of the results of your settings. And a High/Low Switch lets you choose between two overall levels of ratio. The Snake Charmer is equipped with other controls for Attack, which determines how quickly the gain reduction kicks in, and Release, which determines how long the gain is attenuated. Finally, the High-End Emphasis control fine-tunes the amount of compression applied to the top end of the guitar signal. |
