Tube preamp
2 inputs 2 outputs
1 1 XLR jack for each

UTILIZATION

Just a knob of preset I leave mine on for really the valve's lamp (it is on that if you leave neutral on it is useless da see a tube amp)
need manual

SOUND QUALITY

I love me a lot on his
I m used to play live on a sound system with either an electro acoustic guitar or a bass. I do not poses major brand instruments can be and am not very demanding but its got me fits

OVERALL OPINION

I have the last 6 months
frankly I like the sound and simplicity of use
very good value for price
the default of c Berhinger is sometimes the reliability but not the switch no problem
