Features already described ... Tube preamp, a clear channel / channel saturates. I was looking for a big sound simple precise and powerful sound with easy studio or on tour. I have an Ultra Stratocaster Marshall JMP head and a lamp that does not saturate the channel.

UTILIZATION

I chose it for its simplicity. Good clear sound and great saturation.

SOUNDS

I plug it directly on the head with JMP all pots thoroughly ... Saturated fat sound. Rather lens (Especially with the head JMP that "shines" not bad!). Attention to the breath when you push the saturation. the lack of bass reported by some can be a longer tour. Too serious and a sound engineer just limit it gives you a dirty his drooling.
For the clean sound is clean and there is not much possibility just the tone control. Again this is what I wanted ... The equalization, the effects I'll leave that to the studio or the sound system. I need a stable or that I am.

OVERALL OPINION

I have 15 years. I have many turns and is a studio album. Lamps and knobs are original and still he walks nickel. I tried different racks, pedals and other pre-amps to get a good distortion at the time and I confess with my budget so it was by far the only one to approach a its pro.
