Just wanted to provide a few comments on my two-months old Ampeg SVP-CL preamp. In short, I'm really satisfied with the thick, full rock tones I've been able to dial in. I A/B'ed it with my back-up preamp, an SVT-IIp with three Slovak JJ's. The SVT-IIp has a warm, full mid-rangey sound that ends up sounding sort of "eh" on its own, but really seems to work well in the mix. That said, it's a "one-trick pony" and if you don't want that sound, you're sort of stuck. One key feature I really like about the SVP-CL is the five-position switch up front that more or less selects five "models" of amp--flat, low-cut, SVT, SVT+lows, and (for lack of a better description) Dub. I've found myself switching among these settings to quickly grab a variety of useful presets--a faster, if less flexible option than having a graphic EQ onboard. For example, for a reggae version of "All Along the Watchtower" I can hit the Dub position and play with the side of the thumb--highs become almost instantly inaudible. Then, back to fingers and the SVT+lows for a cover of "Blue on Black". Grab a pick, switch to the regular SVT setting for a Nickleback cover. In fact, that setting really enhances just about anything played with a plectrum. Once past the initial shaping section, I've kept the EQ pretty consistent. I vary the midrange setting (setting 3-@800) depending on how hard I need to punch through distorted guitars. I'm still getting a feel for how I want to use the ultra high and bright buttons. I may just continue to tweak them based on mood and room. So, overall plusses on the SVP-CL are: mute switch, intial five-position tone shaping, relatively low noise, and of course, top-notch design and construction. (Plus, who doesnt love the bright green glowing logo?) What I miss from the SVT-IIp-lows button, ability to get absurdly, over-the-top rude in the mids. I'm enjoying this preamp as much as any I've owned and recommend it highly. Someday I may play around with some of the four tubes. But I see no reason to at this point. Oh, and I paid $450 for this pre at Washington Music Center.
