Well, you might be on to something here... IMHO, the joints, the quality & quantity of the joints definitely play a role in recreating the Express sound.
That is why I didn't write about the wire, just in case it has a mild effect, the impedance switch is just a switch, and I'm sure it has no effect whatsoever. Still the wire if it does has an effect it must not be noticeable to the average ear and even less noticeable playing the amp with the band on stage.
So - to clarify - would any manufacturer of non-irradiated red wire with the correct amount of appropriate conductor strands, be ok.
Or does it have to be Columbia wire ?
Actually some of that is true when you get down to impedance it all starts to matter.
C'mon guys...a good connection is a good connection. There ain't no magic in the solder joints. The impedance of a joint? That's funny. It's just resistance and any small deviations in a good joint don't make a bit of difference. This is starting to sound laughable. Flea clips don't add or detract anything except esoteric nonsense that has nothing to do with tone. It's starting to sound like some here may sail off the edge of the earth. Our understanding is better than that, isn't it?
Sorry all the parts matter if you want the exact tone.
Each one sounds different. So the exact tone of what? You can match the parts all day long and it won't be exact, so that's not a realistic goal IMO.
