Bass and terrible Magnetic interferance

    Wow, I just bought a lovely SansAmp bass driver. Beautiful tone. I turn up the tone on the bass and driver to get that lovely high end twang I want from my bass.

    However I'm getting horrible magnetic interferance from my bass even when I'm 20 feet from my studio monitors and computer monitor. I'm recording solo and have certain length cables, so it's not like I can just walk across the house and play. Turning off the computer monitor does not do that much either, only removes certain frequencies of interferance.

    Anything I can do to reflect or limit this crapola?

    Single coil pickups?
    Try turning the direction you face, around the points of the compass. You should find a deader spot. Adding all that top doesn't help.

    ya, I know, but the top end makes the bass sound like a real instrument in the mix, not just this low hum. Gives it punch and life.

    The pickups are bass pickups... one p-bass and one jazz. I think this might have to with the shitty pots and poor wiring in the bass. Thoughts?

    You can also try turning off any extraneous gear in the studio while tracking bass. A lot of digital gear radiates a lot of crud.. Treena says there is an after market ground strap available. Ask her about it in the Guitar Bass forum..

    Nope never used it! Never heard it! I don't know nothin' about it.. It could be the best thing since sliced bacon! (really!) :D

    Breezes I think you are on the right track regarding your bass, could be a small grounding issue that pops up when you boost hi's with the Sansamp... does the buzz start/stop when you let go/touch the strings?

    Also could be bad sheilding in the pickup cavities which is easily fixed.

    I assume you've also tried swapping cables? Also, do you have another instrument you could plug-in to the Sansamp? It may be the box itself has issues.

    I just solved a similar problem. here are my suggestions:

    1. Buy copper shielding and shield all internal cavities of the bass (should be done anyway)

    2. Like Kurt said, turn off all equipment and slowly turn back on until you identify the exact equipment causing problems.

    3. Even though the monitor is not the entire problem, I would recomend recording with it turned off.

    4. Test out recording direct and then adding that bright high end as a secondary patch through an eq.

    Hope this helps.

    My P/J setup with Seymour-Duncan Hots is pretty quiet but my Precision with Hots buzzes like a mofo around computer monitors. . . go figure!

    I agree with the above suggestion. . . turn off your monitor(s) as well as anything else you don't need (including lighting) during recording.

    And congratulations on the Bass Driver. . . I couldn't live without mine!

    PS: BTW, before adding all that high end extraneous noise using your SansAmp, is there a reason you haven't tried cutting your lows and boosting your volume in the mix first? (Or have you tried that already?)
