So madbassplaya and I are chatting about upgrades and whatnot and he posed a question to me about Bart preamps in general... Now I've had numerous basses with them, but they had Bart pickups and I will say unabashedly that I HATE the sound of Bartolini pickups. I've tried their different pickups with other brands of preamps (and passive), but found that the pickups were what made me sad. For my playing style, they don't work and I'll leave it at that. I never had the chance to swap the pickups in basses that had the bart pre, they ended up sold before I could do so. I've had EMG, Aguilar, Sadowsky, East, Audere, Musicman, Tone Pump, and maybe others. All of those, I've tried with pickups of different varieties that made me happy, so I feel qualified enough to judge their qualities against what Bart makes. So... how do Bartolini preamps sound in comparison to others, when not mated to Bart pickups in particular?
