Are there and thoughts about gear that has been modified?
I.E. Guitars with custom pickups, or hardware.
Modded amps or whatever.
I don't think we can catalog these custom variations, as they are effectively "one offs". I think we even have to be careful with factory installed options... Something to ponder for sure.
Discussing particular examples is always good!
Note that guitars are not within the scope of Gearogs at this time - read more in the he wiki under 'scope'. This is open for discussion though!
Maybe a way to add modifications to equipment in your collection.
I mean, I have a Thorens tuntable with a modified SME 3009, for example
