Well described in prior reviews.
What I remember is a big (huge) power of 300W, while lamp and two built-in effects: a compressor and graphic equalizer.
It's also very heavy to carry.
This head is tested with the cabinet Sunn counterpart 4x10.

UTILIZATION

It's not that simple to solve as many possible settings.
For me what works best is set at the middle and boost slightly acute and low and finally manage it all with volume.
The good point is that there are lots of possibilities!

SOUNDS

The top for its rock, blues.
Although Péchu. I slapper and playing finger while ringing.
The sound is right, accurate (not rough) with the dynamics.
I played first with a low Warwick Streamer LX and now with a Fender Victor Bailey.
I reached my ideal with the fender and I find the sound more balanced with the warwick.

OVERALL OPINION

I bought it in 2002 during the resumption of sunn by Fender.
I'm not disappointed at all.
I got the sound I wanted to involve a low fender Jazzbass Victor Bailey.
I recommend it if you want to sound rock, blues, Péchu and typed a bit old.
If you are looking for a modern sound, I think it's best to go your way.
