Well I strung the B string while leaving the rest of the older strings on just so I could get somewhat of a comparison on the sound of new vs old.
First, the feel, it's not slick like a flat, but it's close enough. It sounds a little clanky to me. What I mean by "clanky" is say when I press the B string down on the fifth fret to play an "E". You can hear the string slap the fret. Now if I'm very direct, quick on the note, and firm, that "slapping the fret" sound is very diminished. But play a little sloppy and the strings are going to tell on you just like a new round would. We all know that will go away with use. So for now a little fiddling around with my amd settings and I can eq the clankiness out fairly easy.
I'm running all sound tests using a Hartke HA3500C head into a Hartke 410 cab, and I have a Sansamp BDDI running into the fx send/return with the head's fx balance knob sitting at 50/50. The head's contour knobs, basically a LPF & HPF are very useful for this at the moment. How will that translate to using this bass with these strings on my GK gear? Don't know, and won't know tonight. The other piece of gear I'll test as well will be running direct into a Zoom LiveTrak L-20 from the bass, and running into the L-20 via my Sansamp BDDI.
The thing I hate the most is that I have gotten away from using rounds and sticking mostly with flats until I bought this bass. It had rounds, but very worn rounds, and although worn, they have been producing a tone that I do like. Will these Silencers get there? Probably, but how much use is it going to take to wear them out enough to get there?
It's kind of weird, most of us want our strings to last a while as they are not cheap, but here I'am wanting them to wear out rather quickly.
