Transistor amplifier, sub 250watts 4ohms and 500 at 2 ohms!
There are so many settings and connectors that you get lost a little at first but a big equalization in frequency.
There are also 11 presets ranging from simulation tube through a modern sound and the right to a much more fuzz and distortion ^ ^

UTILIZATION

The configuration is simple but complete, you take the time to shape your sound! Whatever may be said 'good' sound is within range of settings, but once found we let go with 5 presets undefined users available. Its crystalline, very fat or very heavy, all there!

Manuel could not be more clear!

SOUNDS

I play on Corvette Stingray and the puree and it sends the 2x10 ^ ^ of the same brand cashing great load (they are super light, almost Markbass)
We can ALL get this amp, just take a little time to enter the operating

OVERALL OPINION

I use it for almost 1 year and a half, I appreciate its size, weight, design and above all the sound generated by the girl! After trying Hartke, Ampeg Gallien and even this is the Yamaha that I chose. Too little known, it deserves better home
Good value for money, I would do without this choice Hesis.
