I had the first properly loud jam I've had in many years the other week so i took my main three basses. Despite the amp supplied in the jam room looking quite old and worn i was quickly able to get a great sound out of my Bill Lawrence P46 and flats equipped Franken P bass. After a couple of songs i plugged in my Ltd 8-string with soapbars pickups and active pre which absolutely roared. Then i tried my Fretless Jazz which has a Squier 70's jazz body and pickups. A couple of bars into the song and I could barely hear it. I gradually took the volume from 2 o'clock round to about 5 o'clock and it was still completely buried in the mix. I jacked up the gain a bit too and it was barely audible and i didn't want to take the chance of pushing the amp too far. Now, I'm sure with a bit of time i could eq the amp to get a decent tone but then it would require a complete change for the other two basses. Is there any pickups that could compete with the P and the Soapbars without having to radically change the settings or is this just what you have to deal with in a Jazz with single coils?
