Should we still make the lodge?

Christia, 16.07.2011
The ampeg ... used in so many bands and so many styles ...
I use it mainly to play metal, or it perfectly fulfills its role coupled to a 410 hlf and a corvette $$ bk.
I never had to complain about its power that already seems unlimited with a cab on two in stereo.
Small flat anyway to the complexity of the settings with the graphic eq, and the sotie xlr back which works only once in 10 (can be a mass problem on my head).
So warmly recommended if you are looking for ampeg sound and you are not afraid of long settings (otherwise it is ampeg svt CL).

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.
