Powerful - powerful sound

Guido aus R., 09.11.2009
I had already played the amp live here and there and was positively impressed, now that I've been playing it myself for some time, this positive impression is still confirmed.

The amp sounds like an ampeg should sound - punchy, warm and precise. The quasi-parametric control with the 5-way selector together with the treble and bass controls is already very effective. If you add the ultra-high, ultra-low and bright switches, the result is unimagined sound variations. And then the graphical EQ. Admittedly - you can also set bad sounds, but this is not a problem of the amp but the operation. Recommended for the start: Ampeg has suggested in the manual half a dozen different sound settings. If you try it and take the personal best as a clue to continue experimenting from there you will surely find 'his' sound quickly.

I personally play the amp in dual-mono mode with 2 4 ohm boxes. The performance is absolutely convincing. Gain - regulator adjusted correctly - Master at 11 o'clock - that is most then already too loud (me not ;-)). The Amp is thus powerful but still not long in the end - in contrast to many other amps, there is still continuous power up to the stop of the master. He is definitely going to play on all the stages. And that completely without any strain.

Further for me very positive:

- the mute switch in conjunction with the tuner-out, which allows easy, silent voices between the pieces.

- the built-in 'wet' DI box, with which you can finally give the sound of the amp to the mixer without long discussion that you would have a micro instead of the upstream DI box would like.

For me, the only negative point: The Potis, especially the Poti buttons. Works quite cheap and egg turning. In addition, the stroke on the buttons is difficult to read depending on the light, which is not helpful on some stages when setting. However, the amp is well processed.

Exception amplifier

Paul336, 11.08.2011
Exceptional in every respect. There's no need to say, Ampeg is THE absolute reference in bass amp. A big sound of incredible sharpness, a great flexibility in the settings, and huge possibilities of connections, all with a great ease of use. We only regret not having the manual in French, or that the part in Spanish is incomplete. I have not yet tried it live, but the sound is exactly what I hope, even without any adjustments. These will only help me to calibrate the sound according to the type of scene and the space in which I play, as well as the instruments that accompany me (etc). For now, I plug it into the SVT410 HLF. We will see later for extensions ... I will also see how it sounds with a double bass very soon.
