Dunno, dont use ebay.
But I have sold/otherwise parted with things that really were good, and I had very good and genuine things to say about them, but other concerns outweighed it (just taking a break from tracking, through my lovely VHT CL, for example, which I wouldnt have if I didnt part with 2 rather nice ibanezes; I needed the guitars less than the amp, sold an epi LP that rivaled decent gibsons in built, woods and general sound and feel because I didnt get on with the neck, etc etc etc)
Crystal lattices destroy electrons. Presumably then transistors make positrons. And metals in fact arent made of crystaline structures (which they are).
