Very easy to use!
Nothing to say, knob effective, robust and fairly fine tuning!
A turie, I would not make too much because it's my first compressor is worthy of the name!
But I get to "energized" from its very heavy and its quite late,
I am very happy, simple with a good grain.
Do not hesitate I think it's an excellent price / quality ratio I 10 but because of its in its price range! it is excellent (be careful nonetheless the result of the brand lamp (original) sometimes works inatendu).
PS: I Sovtek lamp with better mastery!!
