I went into Mars music today and played a modulus quantum 5 with the Bart pickups. I played through a B2 (the same I use) and a very deep mesa boogie 4x10 (asking price for the cab was 799 but i did not pay attention to the model #) The tone was so mellow and deep. I am not sure if it was the Bass or the Cab that sounded so sweet. I may have to invest in Mesa boogie soon. But the Modulus played pretty smooth, 2200 asking was a bit much. Gard got some good deals on modulus?
