Hello! I bought an Ibanez Soundgear SR840 off a mate a while back. After a pickup died I fitted some Nordstrands in it (Big Splits??? can't remember the model). I have no idea what it originally cost (my mate bought it 2nd hand too), or have much info on it (took me a while to even work out the model). I was just wondering if anyone has any idea what it's worth/how good it is and is it worth spending any money on. i.e. should I consider changing the preamp to something like an Audere or maybe Nordstrand one? Is the higher the number the better the model (i.e. an SR840 is better than a SR7xx, or SR500, or does it not work like that)? I'm not in the market for a new bass, but if spending £120 on a preamp will make it sound a lot nicer, especially since I already changed the pickups in it, then it seems like a good idea, but if it really isn't worth it for the quality of bass then I don't want to try "polishing a turd" as it were. The only details I know are these... http://www.ibanezregister.com/Gallery/basses/sr/gal-sr840.htm So it has an Accu-cast B20 bridge, and a "1V 1B VARIMID 3LC 3 BAND EQ". Even if you know nothing about this model, if you can make suggestions to how good you think it might be, and whether that factory fitted preamp is any good or not, or whether the thing would definitely sound a lot better regardless if I changed the preamp then all suggestions/tips are welcome. Cheers!
