This is an all-tube 30W combo (supposedly)
The connection is rather limited, the effects loop is un'preamp out-power in '
There is a reverb

UTILIZATION

The panel could not be simpler, for it is soon compelled against any attempt to get a get a decent sound
I do not remember any guide, it is not in Boogie
Boosted channel is not bad, rather typed marshall, but lacks a bit of serious

SOUNDS

I used to jazz fusion, with a gt luthier, emg kit, a TARS and also a gibson 335. I never managed to get a clear correct.apparemment is the big problem with Rivera / the light crunch right away you push the amp beyond 10 Watts.
The overdrive sound is OK if a bit skinny.
This is an amp that I have not kept long, as unworkable live.
I've never bought from Rivera.Je did not think a manufacturer that reputation could pass as a mediocre amp.

OVERALL OPINION

I tried and even owned a substantial number of amps, from 20 years of semi pro career. Tip: classic 30 x2 in stereo with vintage tube screamer and 30, you can not beat, even in boogie, and a reasonable investment
