Hey all, I feel like sharing my experience. It's a newbie experience and my opinion is not worth much, but just for the heck of it, maybe some other newbies can relate. Here goes: I finally got me a bass after 18 years of guitar. Squier VM Jaguar bass second hand for a steal. Hooray. Got the strings off in a hurry and replaced with Blue Steel medium lights. Why? Because I know the guitar strings have a little bit more character/color/flavor than most run of the mill brand pure nickel or nickel plated. Then I see that they make both stainless and nickel plated. Ooops, I had not noticed that, but what I bought was stainless. I did not file the nut or anything, just did intonation. It was a big improvement over the "stock" strings (can't really say as I have no idea what they were but they were dead as a doornail). My amp is a Rumble 100 2x10 with Eminence BP102's in it. The speakers don't have a whole lot of highs FWIW. Then I replaced the bridge on my Jag with a Fender high mass type (Badass clone) off ebay. This was a big tonal improvement which made the bass sound like a higher quality instrument; more attack, deeper tone and more sustain. Then I got a P/J set of Fralins second hand and wired them in. Who the heck puts Fralins on a Squier? What a newb. I have done a LOT of pickup swapping on guitars and I know it makes a huge difference so I just did it and they deliver the goods. Righteous P tone and righteous J tone, couldn't ask for more (except maybe the split J to kill hum). Then I finally bought Chromes in medium. On guitar, I only like flatwound for jazz and I don't play much jazz anymore. The effect on bass is nearly the same, with deadened sustain but these are surprisingly bright (as everyone says). I had to tighten the truss rod a quarter turn. The tone all-around is fatter and I find it's just right for bass. I personally do not think that many players need all the treble available with roundwounds. Go ahead and flame me. Feel preference is another story. Now I don't really have bass chops yet, but I have ears and slapping is the most affected. You can't get the usual nice "boing" out of your thumb. Yeah, you can still do it but it's not as juicy. Everything else sounds as good or better to my ears. Really. You can get into that old school territory. You lose the finger noise and no annoying zing. I guess there is emphasis is on the fundamental like I have read people talking about. Tone is rich, sustain is still very good and flexible for most styles I can think of except where you NEED the zing and treble. To me that's not a bass' role in the band. Granted my amp is not very good at treble anyway. I even went back to the rounds, then put the Chromes back on and they are staying for a good long while until I feel like trying something new (and there are plenty other strings out there). I would not mind something a tad wee bit more boingy so I could get a nicer slap thing going, maybe I'll try rollerwound next? I didn't like halfrounds on guitar. I also don't see myself wanting to go any darker than this. A buddy of mine is a pro bass player and luthier (Pierre Erizias) and he will only use flats. I was skeptical because he goes for ultra-smooth sounds, no slapping in his style and a lot of fretless. His basses sing like no tomorrow. Now I won't have his chops for at least 20 years (if ever) but I like what I hear. So there you go -I'm a new convert. I would love to try a Portaflex or other all tube setup to hear this bass even more warm and vintagey.
