I've asked this question of other forums too but wanted to get the TB collective's POV... I had an Ampeg fridge. It sat real nicely in the band mix most of the time but I tune to D standard and sometimes drop C and it would turn to mud when playing 1/8ths on C or D. So, I looked for something less muddy and traded it for a Schroeder 1515. Less muddy to be sure but it's way too present in the mix, hifi sounding, and basically the opposite of warm. So, what say you? I've been told the Bergantino NV610 is the stuff when paired with the old Ampeg heads ('76 SVT is what I have). Also thinking I should just go back to the fridge or Ampeg 610. Any other ideas? Really the only things I disliked about the fridge were the 167lbs and it's tendency to mud up at low hertzezez.
