I'm looking for a rewally nice warm,tube amp meets Pbass tone,but i'm very used to active basses,(my main axe is a sadowsky J..) wondering if this'll give me a nice warm, vintage-y John clean tone..a la' John Deacon.. or should I stay passive? how's the tone on these? and the preamp? also thinking Sadowsky Hybrid or Glaub,I like a 1.5" nut width.. anyone own one of these? care to give me a brief review of 'em? thanx!
