Mesa Boogie Bass 400

Any lamp 300w amp.

The connection is very comprehensive:
-Front: effects loop, input 1, input 2, footswitch for the equation graph.
-Rear: 1 x XLR, 2 8ohm output jack, 2 jack output 4ohm, 1 output jack slave out with its volume, a second effects loop with volume, ground lift and fan speed (cancels, slow, fast) .

Settings: gain 1, gain 2, Master, Treble, Bass, Middle and switchable graphics equation.

Compared to a Bassman is very complete.

UTILIZATION

The config is pretty simple, if it is confined to normal use. I never tried out the slave, used to connect a power amp, I understand.
You can choose to enable or disable the equation graph. It can obtain more sound, but is not required to ring the head properly.
The manual is in English. But he does not learn much. That's the kind of amp that one discovers in use.
The settings are pretty special. It can boost or sink very quickly, so it will be necessary to spend a little time to find his sound. Once mastered, it is a beast.

SOUNDS

For my part, it is quite the style I practice. I play rock / noise and trance / dub / electronica.
I played with precision and lower half body maker with micro Darkstar.
The sound is very fat. With a lot of bass. It can be very bright, but never clean. It's pretty much the opposite of an amplifier, hi-fi style Eden, Epifani, etc.. It has lots of character. This is not a model of versatility, and that's why he me.
I love his sound crunchy, oily. With a 2x12 "is a treat.

OVERALL OPINION

I've had several months (I forget how much).
I tried a lot of pre amp: Peavey TNT, Yorkville Hartke HA3500, 160 Crate, Trace Elliot, Ampeg Portabass, Markbass cmd121, Fender Bassman Silverface, etc..
I love the tube sound very rough with a hybrid connection or transo, and the equation graph.
I do not like the weight (approx 30kg), and the fact of not being able to connect my MS-10 without it buzz.

It gives me the best amp I had. I do it again this election unless I needed a laptop config / nomad. For anyone who has room, and friends to help him, it's great.
