I got to play a Lake Placid blue 4 string at a guitar show in Charlotte. These basses are fantastic and sound great. That pre amp is very sensitive,smooth,growly and it's not clacky sounding like some active pre's are. I played through one of their Low End bass pre-amps( they have a desk top and rackmount versions), which has minimal controls and sounds great. Go to the link above for their web site and look for them under amplifiers. Good stuff!
