UTILIZATION

As its name suggests and is well marked on it, that's metal. the settings are very easy to obtain, 2 or 3 rounds of wheels and hop hop hop go.

No need for manual

SOUND QUALITY

I play it with a BC Rich Mockingbird with emg 85/81 (active pickups) and a Sennheiser HD 200. The overdrive sound is simply great. Having the headphones on to great satisfaction.

Small flat, the clear, especially with active pickups, is almost nonexistent.
shame because metal does not ring with nag necessarily contrary to what many people think

OVERALL OPINION

I use it regularly for 1 week and I find it very useful, especially since the day I board not the time to play, I work at night. I left that night when I come home from work for me metrre. And then I found quite useful. I do not wake anyone.
Sound, headphone jack and cable, the big foot. I play when I want and at any time.

To my knowledge, there is no headphone amplifier as practical and well designed.
for € 39, we have no right to complain but this was simply not the right to criticize

I would definitely do it again this election and I plan to buy the same version AC30
