Como veo que nadie parece conocer estos pedales, me he pillado uno para ver que tal son (y porque me ha dado un ataque de GAS incontrolable). El chisme en cuestión es este:
La información que dan con el pedal es esta:
[spoiler] The VT1-Drive uses a single 12AX7 (ECC83) valve to generate classic pure valve tones. The VT1-Drive is a low to medium gain effect and is intended to be used in front of a valve amplifier, but will also work well with solid state amps. The foot switch provides a true by-pass and the blue LED backlight indicates if the effect is on or off.
There is a guitar and bass version available so please let us know which one you want when ordering. There is an extra i/p pad pot on the back of the pedal on the bass version
The controls are very simple, i/p pad (bass only), Level, Gain, Colour level, 3 position Colour select switch and a bright switch.
Level sets the output level of the effect to your amplifier, there is a fair amount of gain generated by the valve and op-amp and this will overdrive the input of your amplifier.
Gain sets the level into the second stage of the valve and hence the level of gain. Use your volume control or on your guitar and/or the i/p pad on the bass version to control the gain on the first stage of the valve, you will find that the VT1-Drive responses very well to this and you can control the break-up distortion like this.
The 3 position Colour select switch is used to select Colour 1, 2 or non which is the centre position. When Colour 1 or 2 is selected negative feedback is introduced into the circuit the level of which is adjusted with the Colour pot. The Colour effect is best heard at high gain which is an increase in distortion and compression.
The By-pass footswitch provides true by-pass of the effect.[/spoiler]
La idea es darle un poco de colorcillo al bajo, por los audios que he escuchado por internete da un sonidillo interesante (tambien se puede usar como overdrive un poco mas bestia).
En cuanto lo tenga os digo que tal (el pollo al que se lo he comprado es el que los hace y tiene que fabricarlo todavia).
