OVERALL OPINION

I use it for 1 month. test together with sax and tp, rpeter. (only for a muted tp): trs for the live well.
I love the most: the clamp (spring force) trs tenacious.
sound: trs good record, no staining,
output level: Attack of the gain knobs on the trs tot with a big room to maneuver.
trs solid overall compared to E608 or Ramsa
is the clone of the AT pro 35 AX except the cell that is diffrent (made in taiwan)
Q / P unbeatable 59 in toto.
what I like least: the cable a bit short.
MODEL number with or without power supply unit 48v in a box (plastic carrying case, while being protected)
I saw the price Do not hesitate. vrifier time now.
