2-channel preamp Mesa all lamps, 6 12AX7A (preamp Dual Rectifier head).
3 modes per channel

a master for direct output (recording to mixing desk)
a master outputs for live (power amp for the stage)
a master for live solo (lead and chorus)
an effects loop (send, and retrun L & R mix)
2 channel selectors on the rear (channel 1 & 2 and Solo) a switch at the front entrance to the pedals Mesa,

Would a midi interface was top!

UTILIZATION

Easy to use, everything is in front, you branch scratches and sounds!
the manual and friendly, a lot of text but nice.

SOUNDS

I love the sound Mesa (saturated channel), but it's hard to play since it renders to perfection how to play, whether its light or saturated, which cuts both ways! but great nonetheless.

OVERALL OPINION

Super preamp (the blow your hand and too much new)
tastes and colors change from person to person, but it is undeniable that it has assets of sacred in his pocket, power, and precision!
