Gigged with the Ampero last night. Not an effectsy kind of band so used it as a preamp with some compression and tone shaping, just using the power amp section of my amplifier.
In fairness the Barefaced cabs I used make anything sound great, but it really was remarkably good. Used the Squeezer comp and Ampeg pre and every note was even, punchy and crystal clear. Well, not exactly clear, as it had a bit of rough around the edges, but I could hear it clearly.
Impressed.
