Trying to remember what buying and selling I've done.
Early on, I bought Gramma pad from thebrig and a Line6 multieffects unit from Rich.
I bought hooky_lowdown's Squier Matt Freeman, despite that ad saying withdrawn
I sold the pickup from that bass to Can'tthinkofausername, who asked after it when he read that I had replaced it.
Think that's it?
Edit:
Bought some strings from danbowskill
