Want my P to thump

    ;) I have a SX P bass which sounded great stock but i want to mod it to have a blues thump i crave. I added Duncan Performers and power flats and have it close but really think i could get it better. Would new pots and cap help....should i try 500ks over the stock 250k pots and what cap would help?

  2. not really...if anything 500K's will "open up" your sound and make your bass more transparent sounding.

    I think a 0.1 uF (a.k.a. 100 pF) capacitor is more of what you're after, as it will give you more roll-off of treble, leaving behind more of that bassy "thump"

    I have a GK 210...300w but play also thru a band members ampeg 4 a SVT i think and a 2x15. I want to add a 15 cab to my 210 to get a bit more mids from the 10s and bottom from the single 15 ...i think the two 15s are loud but can get muddy. I thought i needed to get the bass sound first and then amp and eq second ...but maybe not.

    Perhaps you should describe what you mean by thump. Examples?

    For me, P + flats = thump in its purest form.
  8. My 2001 MIM P no longer thumps.

    Shortly after buying it, I replaced the strings with TI Jazz Flats. These are a wonderful string with a middy tone over a very long life. I suspect these strings do not thump.

    I replaced the MIM pickup with a Duncan SPB-2, Hot for P. This is a VERY mid-rangey pickup and wasn't at all what I wanted. Perhaps it was the combo of SPB-2 and TI Flats..

    I replaced the Duncan with a DiMarzio Will Power Middle. This tamed the middy thing quite a bit, plus gave me the option of wiring in series/parallel. I find this useful.

    Still no thump. I'm thinking a string changed to either DA Chrome Flats or LaBella Deep Talkin' Flats is in order. Either is much easier than a pickup swap.

    TIJF's are wonderful but that ephasis on harmonic content and the kind of woody sound cut's down on 'thump or thud'. I haven't tried the Labellas. I use Chromes on my fretless, I may try a set on my P just to hear. Chromes are also a very 'detailed' sounding string with a lot of harmonic content. They really sing on a fretless. I prefer them to the TIJF for the higher string tension they provide.

    I used the old Fender 9050 flat for a long time. Mostly on an L1000. Excessively bright for a couple of weeks. When they settle in they thud like there is no tomorrow though.

    The other string I would like to try for a flat is the Rotosound Steve Harris. I've heard good things about them.

    .1uF is NOT the same as 100pF

    .1uF= 100nF=100,000pF
