It is a MOS-FET, it also contains two transformers rings (not ask me why!), 200 watts, the connection is more than up to the machine, specifically the DI Out is excellent! !dropoff Window !dropoff Window
It has 2 volumes Solo and Ensemble ..... via a foot switch allows to pass .... 2 different levels ... yeah! !dropoff Window !dropoff Window !dropoff Window

USE

The sound quality of emblem, the musician who makes his fingers, especially on bass where you have some form ..... if not ...
That said, I've noticed that do not like being on the floor, you MUST raise it to take advantage of all the grain of the low and / or bass.
There a "Colour" button hollow midrange and slightly boosts the bass / treble, I rarely serve .... because it is to a certain volume we really perceive the qualities of this amp: Precision (like my bass the same name), transparency, articulation, respect TOTAL stamps sent to it, balancing frequencies ....
In short, almost HI-FI, it is intended primarily to acoustic instruments, so the amplified acoustic music, but whether in jazz, variety, blues, funk .... well, not metal whereof the electric bass feast !dropoff window !dropoff Window !dropoff Window !dropoff Window !dropoff Window
For my part I was offered to me for my bass until I plug the electric bass: result I sold my bass amp! !dropoff Window !dropoff Window !dropoff Window

NOTICE GLOBAL

I use it for 7-8 years, it is tough, it comes with a padded cover but I put it screwed corners in black plastic because offer him a flight case is overpriced (but I seriously think), the combined XLR jack is fragile against by the startup switch is hyper misplaced ....
These are the only things that I can blame him, otherwise he ridiculed my head Trace Elliot with his 4x12 ...... without laughing, I speak in terms of sound, clarity, nuance, no decibels, Warwick Thumb BO 5 of that time has never sounded so good ... and for decibels: DI Out, sound system, and gas!
What worries me now is that AER built a BassCube II, 500 watts of his madness (3000 euros, have ale ale ...!), If you see one, try it! You'll see!
