Yes, they were too until I tried the wizzard pickups, which is what my series/parallel bass has.
The MFDs are really too hot. I think that is why they toned them down for the M2500
I often feel with my basses, I should probably just put all the controls outbourd, play it for a bit and then take the pots and switches out and replace them with fixed wiring / resistors at the values I want! Leave it with a volume with push to kill.
Well, rics do sound a bit weak, which is not like quiet - all my SRs souned quieter than the L2500, but they didn't sound weak, they just had less volume.
