Since I'm in the market for a new amp, I went to my local Guitar Center today and checked out the selection. I tried just about everything they had, Gallien-Kruegers, SWR, Ampeg, Fender, and I was most impressed with the SWR Silverado. I've been looking for a powerful, great sounding combo that can handle small clubs, but could also handle larger places if and when I start playing larger gigs. The amp had balls and sounded huge. I could get a wide variety of tones out of it, from a dub-like sound, to brutal metal tone, smooth jazz, I got it all out of this amp. I was mightily impressed. The ability to add a 4 ohm extension cab at 450W also adds to the growability factor. Overall an excellent amp. Anyone else had any experience with these amps? Anyone problems or concerns I should maybe know about before I commit to buying one? All questions or comments would be appreciated. Thanks.
