This weekend, I swapped out my fender Pbass pups for some Quarter Seymour Duncan Quarter Pounds, hoping to wake up the bass a little. I found that the SD's actually deadened it a bit, so I pulled them and returned. I thought I saw a blurb somewhere that a higher Ohm reading meant a stronger pup. When I pulled them to un swap, I measured and found the Fenders at 12.2 and the SDs at 13.2, so a little perplexed that the SDs actually sounded worse - or at least didn't fix what I was trying to. FYI - this spring I realized that have more oomph - especially on the upper range - on my Squier than I do on my AM Pro Fender. So trying to do something to liven up the Fender. It's a little hard to explain what I'm looking for, but I'll try: I generally like the tone to be mostly rolled off (10-20% - think Jamerson, old school Motown), but in some instances I like to roll it up a bit (70-80%) to boost the highs. When I do this on my Squier, I get a real growly tone and all the strings are just generally livelier. I'm not much for slap, but on the Squier I can actually get some noises that begin to approximate a slap tone, but not at all on my Fender - just thud, thud, thud and the pops are worse. For some time, I though I just could not find the technique at all; turned out in this case, it was the tool. I play flats, so not especially looking for slap tone - I'm just using this an example of the difference I'm perceiving - I'm missing the growl on my Fender. I'm going to try a fresh set of strings just to rule that out (using same strings on both basses - not a huge amount of age difference - they're flats, couple of years old so not expecting there should be a tremendous difference - the fresh set is to rule a dead set of strings. Assuming new strings does not solve this, does anyone have any ideas as to what else to try: Do the pots have anything to do with this? Any other pups I can try that may be more lively? (5 string, passive P) What should I be looking for when browsing to get an indication of the pups' liveliness? Is there anything else on the bass I'm not considering that would contribute to a pretty big difference in tone? Thanks .
