«  very good head! »

Tube amplifier, 750 watt. 2 preamps, one transistor, the other tube. Speakon connector for hp, with output effects loop, preamp output, output balance. Knobs to boost the bass, midrange and treble. A footswitch selects the preamp used (transistor, lamp, or mix), and activate the boosters. Two floors of comprehensive Equalisers (one for each preamp): low, medium low, medium, high and medium high. And one nice thing: it runs on 4, 8 or 2 ohms: very practical!

UTILIZATION

Configuration is very simple and very rich at the same time. According to the preamp used (transistor, lamp, or mix), and adjusted, we get very different sounds. And with the footswich, we can use this as an effect. Ex: there's a basic rule with the preamp transistor (its very clean), and is added when you want the tube preamp (gain in depth and volume low, focusing on one or a few frequencies of choice) to make the sound more wild and / or "vintage" (saturation of lamps). The knobs are very reactive, we must learn to use it, but it's easily the mug you want. By putting everything to 0, I have a very good sound, then there is no more than refine. The manual is clear, it explains everything you need on the intricacies of the animal (eg diodes that can well adjust the gain ...).

SOUNDS

The head is generally very bright, very defined sound. it can play both jazz funk that: is any. That's me over at first. Then, by boosting the bass, you get a reggae-dub sound without worry. Can vibrate the whole house if you want to have fun throwing the neighbors.

This head is one of the most versatile I've tried. The power amp is very neutral, it really restores the sound of the instrument. Then we play is different preamp to color the whole.

Third advantage is its power. it sends really heavy, and I never had to push very hard head, even with ten other musicians on stage. it can always keep a margin Groose, so its always a set in all frequencies.

Finally, the extras is the two-stage preamp. In addition to the wealth of settings that it allows (a very clean and neutral with the transistor, the hottest and wild with the lamps, depending on how they are pushed), using the tube preamp that can activate the effect at the foot is really great. it allows a slight saturation or violent really interesting. The boost to the foot of the subs is not bad too ...

I play this amp with a fretted bass (bass luthier type jazz bass 1973), a fretless (musicman stingray 81), and a bass. In any case, I get the sound I want. The sound "acoustic" is really great, very rich in harmonics, and sounds more rock, reggae and funk work really well too.

After this is of course a matter of taste: it was not the same sound that modern ampeg (personally I much prefer this one, much more varied and no less powerful), and certainly not the same sound that an old amp of 70 years. But it sounds really good, no problem.

OVERALL OPINION

I use it for two years. I tried a lot of amps before that, and after that too. I'm quite a fan of old tube amps (I also play on this kind of amps, depending on the sound I want), and for me any modern amp does sound particularly good vintage, not even the head-Genz benz. on the other hand, of all modern amps I tried (including the big ampeg, mesa, orange ...), it is this mind that I prefer (especially for this price range), for its neutrality, its versatility, power, and the little subtleties that I mentioned. Value for money unbeatable for me. And it's tough!
