Crusader Posted June 2, 2014 Report Share Posted June 2, 2014 (edited) Gibson 490R vs 57 Classic Humbucker Hi everyone I'm wondering what the difference is between these pickups, from a technical aspect and personal point of view. They have about the same output and both have Alnico 2 magnets So what is it that makes them different? Are they actually different? P.S. I'm not concerned about 2 conductor and 4 conductor wiring. I'm thinking along the lines of output, gauge of wire, output etc Thanks for any comments Edited June 2, 2014 by Crusader Quote Link to comment Share on other sites More sharing options...
SwedishLuthier Posted June 4, 2014 Report Share Posted June 4, 2014 490R, Alnico2 magnet 42AWG (probably Poly) wire, 7.2 to 7.8 Kohms 50 mm pole spread 57 Classic, Alnico2 magnet 1.94" pole spread (49.3mm), 7.4 - 8.5 kOhms, unknown wire type but probably 42AWG with thicker insulation compared to the 490R. So the 57 will be slightly hotter, with more mid and probably (because the wire insulation) a slightly "drier" sound. This is only based on the specs and no A/B comparison.

Crusader Posted June 6, 2014 Author Report Share Posted June 6, 2014 Thanks for your reply SwedishLuthier The only thing I could imagine was strength of the magnet. They say "Alnico 2" and "Alnico 5" but surely there is something in-between. Thicker insulation is something you wouldn't think of Quote Link to comment Share on other sites More sharing options...
