«  super! »

Much has been said so I will not go on, and.
Mine did not have the original lamp.

UTILIZATION

I do not have the manual, but unless you see an amp for the first time I do not see what it could be used.
The sound is good when we part, but with 4 channels you are looking for accurate sound should spend a little time, anyway we get there because this amp is super versatile.
The only problem when using the weight (50kg it sucks to move, to me it is local repeatedly)

SOUNDS

I play rock and experimental jazz and this amp suits me perfectly for both.
The sound is crystal clear (Fender type amp), the crunch is very interresting.
With the overdrive channel it happens to have the powerful distortion of overdrive until the heavy metal.
The sound is round, warm, but retains all its sharpness and clarity (which is not the case with Hughes & Kettner Tube 50 that I had before and which had a distal type fuzz very messy).
The amp is really powerful, even with a drummer I nag does not exceed 3 volume saturated!

OVERALL OPINION

I use it for 1 year with my Fender Start lonestar and I am very happy.
I tried many styles and this is by far the best amp I've ever had.
Most:
* Versatility
* Quality and clarity of sound both clear that saturated
* Value for money really good
Least:
* Weight
