Phasing sound but no phaser........

Discussion in 'Pickups & Electronics [BG]' started by C.Veltman, Dec 3, 2000.


  1. Hi Bassfriends !
    I have this strange little problem...
    When playing my Squire Jazz the sound phases !
    Not as strong as an external phaser but still ???
    Roundwound strings, bridge pickup, Hartke kick back combo.

    Yesterday I took my stuff to the local Music store
    .....
    I ended up playing theire new American Jazz thrue
    a few of theire amps, but still the sound phases !

    Never before have i stumbled upon this problem
    and neither the store.

    When putting a new set of strings on the Jazz bass
    owned by the store, it got just a tiny bit better.

    Is my brain out of sync ;-) ?
    I know it´s not as the staff heard it too even on
    theire own brand new equipment.
    Is it a currency problem ? We use 230 volts here in Sweden.

    Thank for any help !
    Kind regards,

    I could be wrong, but I think it is the pickup.
    Especially if it has polepieces.
    For every string there is a magnetic field where the string vibrates. IF the string vibrates outside of that field, the sound will change completely. This could mean a TOO-Narrow magnetic field.
    Again.. I could be wrong.

    I have a passive guitar that does this whenever two adjacent pickups are activated. This leads me to suspect that the combination of out-of-phase signals from your pickups may be the culprit. Try some different strings for a start; if that doesn't work, try replacing the pickups; if that doesn't work, try varying (if you can) the position of the pickups. If none of this helps, you're stuck.
     
  4. Think I'll try moving this over to the "Pickups" forum. Maybe you can get a better answer there.

    Yo Brother!

    I had a similar problem with my MIM Jazz Bass. The phasing sound was caused by the pickup (this was the NECK PUP!!) that was too close to the strings. They never caused anyother problems but only phase shifting. I just took a screw driver and rolled the pickup closer to body i.e. lowered and the annoying effect was gone. Take few minutes trying this, but do not put them too low to lose the tone and volume?

    Hej då, Jerry
     
  6. Hello JerryH and bassfriends !

    You are correct Jerry, the problem dissapeared when lowering
    the pick-up ! Never had this problem before....
    It won´t make a big difference as the bass in all
    other aspects is one of the best I have owned.
    It´s a Squire Jazz Bass VJ from 1983.

    Thanks for the help !!!
