Never owned one, but played around with a couple, and one of my all time favorite recorded sounds is Santana through an early one. If you could only have one, which one would you pick? I understand that some are somewhat collectible or rare, and that might be a factor, some are ideally suited for certain type tones (a Rectifier for 90's metal comes to mind). You might think that certain ones are more problem prone and harder to work on than others. Whatever your reasons are, feel free to spell them out. Thanks!
