Hey guys i am looking into getting a new preamp and i am thinking about going with the ashdown or the ampeg SVPBSP. I play a fender Jaguar bass , A fender american P bass with Wil power pup, And a ibanez custom 6 string into a crown XS 500 power amp and my effects are a boss comp and a voodoo labs sparkle drive. The sound i love is a cross of geddy lee and billy sheehan. tell me what you guys think??????
