I'm thinking about getting one of these to replace my Sansamp Bass Driver for a preamp. I've done a search and found lots of praise for it when it came out but haven't been reading much about it lately (last couple months). Has anyone here recently purchased one and how do you like it compared to other preamps you've tried? I'm looking for a warmer sound and definitely prefer the sound of the tube model over the solid state one as heard on basstasters.com. Oh yeah; they're only $430 with shipping from RiksMusic.com.
