I'm finishing up a build (finally) that was originally going to be passive. I've decided that I'm going to go active, however. It's a P bass with a reverse P in the bridge a la Thunderfingers. I want to try the Darkglass on board preamp, but I just got a microtubes 900. I usually go with Nordstrand, Aguilar, John East, or Sadowsky preamps. My question is.. should I go with something other than the Darkglass if they are going to be based on the same thing as the microtubes 900 or is that actually a benefit? If it's relevant, I play in a rock trio mostly using flats but still pretty aggressive.
