All my other amps and cabinets are ampeg. I paired the SWR 400 with one of my ampeg 410 400 watt 4 ohm cabinets and the sound was great. I actually had more definition on my sound from this head. My ampeg heads are very warm sounding but don't have the definition of the SWR in my opinion.
Sound
The sound is excellent - growl, depth, bass, mids, and highs!
Features
The Aural Enhancer and the Bass Intensifier are a plus that makes this 400 watt amp sound like a 700 watt amp!
Ease of Use
The variety of knobs for dialing in the sound you want is awesome!
Quality
The product is well constructed and attractive in appearance.
Value
The price on this amp is very reasonable considering it's quality sound and appearance.
Manufacturer Support
No problems yet! Just bought it September 12, 2007. Played two weekend gigs and the rest of the band went nuts!
The Wow Factor
