Hi there fellas. I've been sifting through the threads here for a couple of days, and no one has tried swapping out the stock yamaha preamp (which is just poor) for another aftermarket one. I have a few choices, trying to decide between the Bartolini NTMB, the Aggie OBP-3, and as of a few minutes ago, the Audere (not sure if it'll fit though without having to mod the 5 holes) Just wondering if anyone would care to give suggestions. The tone i'm looking for is someting with a little more punch as i'm a heavy thumper. The stock preamp is just too feeble, and even when i scoop the EQ, it still sounds very twangy, just not my cup of tea. Could be just because i'm too used to my other basses. I'd love some input. Thanks!
