ics1974 Posted June 5, 2009 Posted June 5, 2009 I bought my SG used. It's a 2005 SG Standard. The guy said they have Classic pickups in it. I asked Modern classics (490r & 490t) or 57 classics. He said that all he knows is that they are classics. He bought it used as well. Is there a way to tell?

Twiz Posted June 7, 2009 Posted June 7, 2009 Hmmm. That's a good one. I don't really know how you can tell the difference. I'd recommend taking off the plastic panel on the back of your guitar and looking at how everything is soldered. Usually if the pickups were replaced, you'll see extra solder on the pots or something from where the original wires were attached. If everything looks pretty clean (like it came from the factory) I think that's a good indicator that you've got the original pickups in there (490/498). What's most important is how good it sounds. If you dig it, then what's it matter what pups are in there?
max2343 Posted June 7, 2009 Posted June 7, 2009 Snip a old Cord and take readings and Match-em up to this Chart 498T-----------13.4K 490T-----------7.9K 57 Classic----7.7k Note the 490 & 57 Classic's Readings are about the same but do not sound a like and I think the 57's have a sticker on the back of-em
drumrnmuzik Posted June 8, 2009 Posted June 8, 2009 I agree but how do I know for sure. Is there anyway to identify one from the other? 1st string - fret 0 2nd string - fret 1 3rd string - fret 0 4th string - fret 2 5th string - fret 3 Strum down once The guitar's cpu will dump the pup code to your amp display.
Tim Plains Posted June 8, 2009 Posted June 8, 2009 I agree but how do I know for sure. Is there anyway to identify one from the other? 490 - neck 498 - bridge Read what Twiz wrote.

If you move a conductor through a magnetic field, then you'll induce a current through any wire involved in the circuitry. In this case the wires surrounding the pups magnets that produce a little signal. It's probably in the millivolt range with almost no amperage. I've never tried to measure it, but it sounds like a fun thing to do. For sure a real guitar tech would know the value. If you have a small wire cutting through that little passive magnetic field, then it's got to be a very low output. Put a 9volt battery on it and you get a bigger output. Between the different pick-ups, there are different types and guages of wire, and number of windings all of which determine the output level and quality. 498T-----------13.4K 490T-----------7.9K 57 Classic----7.7k The above means the impedance of the pick-ups, or the ability to allow current to be induced. Lower impedance means more permeability and higher signal output. Here the 57 classic should give a higher signal output then the 498T for example. Higher permeability should allow more harmonics to be induced and give a richer tonal quality. The higher multiplications of the original harmonics = lower the signal level. You'll even get sounds that we humans can't even hear. C Cool trick these little fiddle toys, eh?
