So after a few weeks of playing this Q5, I am absolutely sold on Modulus Q5's! The Nordstand pre sounds great and has a TON of tonal options, but it sounds a bit too "polite" for my tastes! I can see myself changing it out for the OPB-3 to add a bit more bite! First and foremost, I am a Spector Fan, but this Modulus is one of the best feeling, playing basses I have ever owned! I can see adding at least one more to the arsenal in the future!
