I just brought it home and had a short run with it. First of all, I Like It. I used a epi 410 and berg nv610 with a modulus, Fbass and tobias killer B. Havent had the time to try it with the berg 322 yet (my fav cab!). I had the svp-pro but it was too noisy and the cl is as quiet as my aguilar db680 pre. I think if you take the graphic eq out of the pro, the cl has a lot more tones in it. The pro with the graphic might have more tones but as mentioned in another thread they are more of the same where as the cl has different tones. In comparison to the db680 the svp-cl can be thicker. You can get the 'thick' out of the db680 but the 680 is a very 'fast' pre so it doesnt seem quite as thick. So far I can get the two pre's to sound prety close to each other but they still can each get quite different and have their own voice, if that makes sence. Thats what I was looking for. I like the fack that ALL of the nobs are useable. You can turn them full on or off without getting the tone funny but still change the sound a lot. For an example the eden nav is known for "a little goes for a long way" and when you get them too far the tone gets weird. Compared to other pre's Ive owned: It can get close to the top end of the demeter but more of a mid range top end and not quite as crisp. On the other end it can get every bit as thick as a ashdown rpm evo II and not get as muddy. It is a fast pre but not as fast as the db680 or a EA Iamp. The cons; I think the green logo is too bright. It might be cool on stage but right now, dang, its bright. If you dont like the lights on the eden navigator, you wont like this. The output is very low on the svp-cl. There is a mod for it and its a simple one (and Im going to have it done). So far Ive just used a qsc plx 3402 and this combo is VERY quiet compared to other rigs Ive tried/used. Keep in mind, for my use I need it loud. It might work with the crest CA9 but I havent tried it yet. btw, yes I know there is a mod for the plx amps too. I have to keep it short, I have a gig tonight but in a nut shell, this one Im keeping. All of the preamps mentioned above are very nice but just didnt quite do it for me (except the db680, Im keeping it too) and the svp-cl is one nice pre. Im going to use it for a set or two this weekend and see how it does live and I'll make my next opinion/judgement, just thought Id give a quick review.
