SWR Bass 400 WorkingPro Head, 400 Watt into 4 Ohms, 2 HE, Classic SWR Preamp with Aural Enhancer, new exclusive Bass Enhance Circuitry, 4 Bd active EQ with variable midrange, Effect Loop, XLR Out pre / post EQ, incl. Footswitch, weight 25ibs
I do not want to translate but c'es simple!
Transistor amp, 407 watt 8 ohm x 2 = 4 ohms in Parallel: hp outputs are in parallel therefore include 2 hp to 1 hp or 8 ohm to 4 ohm.
The settings are very fine, efficient (aural enhancer, bass Increase), it adds bass without drowning the sound and an exceptional clarity. The treble is clear without tearing the ears. The conection is on the back panel and full hyper (effects loop, line output, hp etc.).
There are two protections clip signal input and output. The only thing is that 400 W are delivered just sufficient repetition ... and souvdent clipe output at slpaps .. and as I play mostly with Clarke's Alembic ...

UTILIZATION

The settings are fine, the sound is not so easy to find ... just one hour test.
The manual is multilingual.

SOUNDS

With a deluxe Alembic SC 2004, the sound is faithfully restored and crystalline, distinct.

OVERALL OPINION

The best: the sound
the least: it easily clipe
For me it is not powerful enough, the sound is less warm than my Ashdown Mag 300, but it is much more fine and precise that it wins. I redid this choice but an SWR 700 WorkingPro hoping that's enough.

UTILIZATION

When I toured the Lyon shops, this amp caught my attention and I wanted to dig a little deeper into the settings.
It takes some time to find the sound, because the adjustments affect many, it is effective, both in the equalizer of two functions "aural enhancer" and "bass increase.

SOUNDS

I use it with a 1 * 15 of the same series.
I have a very plain setting with a Fender Jazz Bass Mexico.
I play mostly on the 2 + functions as the equalizer.

I love having a round but not stuffed bass, purring a bit anyway (again rock bar), which is quite present and clear (we play guitar bass drums and vocals). I am very satisfied with the tone color of this amp, especially for the price. The equalizer allows you to really work on her. it can range from crystalline to slamming his fat well.

The clarity of the bass is superb. Really a great point in my opinion.

OVERALL OPINION

The pros:
- A full DI output with even a line or instrument settings.
- Adjustments very effective
- Value unbeatable price (1000 euros per head + cabinet 1 * 15)

The -:
- Power limited, should not be a fan of big bass that makes deaf or have a free outdoor transplanting.
- The fan who did a lot of noise! (And that's the only thing that stuff myself, because I tested the 550X was absolute silence). Live it passes, but the studio is a bit ... noisy.
