I use the SMB4A for 3 months. It replaced an original imitation of the brand Cort (I have a Cort G series). Former saturrait despite HARTKE VX series with a 3500 head. So he had to change.

First impressions: - it is hard to hand hold: you must be technical to do what notes make it sound so much wanted his power is present. I'm still in the process of adaptation because I had to change my game (not the other micro rang the strings played frankly).
- He had to redo all the settings for amp and effect (very low offer, and treble it by quickly and I have a hard slap to my overdrive sound very heavy because of its clear sound.
- Well I stop the criticism is because he had to do: it is more than great, it changed everything, he has a huge potato as severe as in the treble, with trimmings of amp lamp mid mid transistor, the sound comes out great (after the bass is meticulously regulated, because at first it even more saturated than the other because of its power. My advice is to tilt a microphone so that the rope from the ground is closer to the microphone.
- Value for money, excellent, but it's not too hard, it's the only category with SMB4D. Other brands making only copies. Paved, that is what is the best

I then repeated the same choice because it has nothing to do with an original microphone and my poor Cort sometimes with ringing tunes lag Jacobacci (quickly though).

I recommend it to anyone who can not put € 1000 a new low and want a sound to a more than respectable.
