I'm about to start a payment plan on one of these two preamps and a couple of cabs....just looking for some opinions before I drop the cash. I've had a chance to use an SVT-3Pro and really liked it's tone, but I've never had a chance to run a CL preamp, or any older CL heads. Basically, what's the tonal difference between the two? Mids? Lows? Modern/vintage? Ect... The plan right now is to run whichever one I get into a Mesa 2:100 power amp, and an Ampeg 4x10 & 1x15 stack. I'm using a passive P/J style bass....I haven't made up my mind on whether to use vintage or overwound pups yet as I'm waiting until I have my amp setup to decide. Thoughts/suggestions/comments? Thanks.
