sp-1200 model numbers Quote: That's not the switch I'm referring too. What's the serial No? That picture is grey SP. Show me the same switch on a black one. Haha, well then what switch are you refering to ? I made this pic from my black first re-issue SP1200. It's about the model no. not the serial (unless you have a list indicating which was which). To clarify : 1. Original grey edition SP1200 / SSM2044 filters / model no. 7030 (square power switch) 2. First re-issue black SP1200 / SSM2044 filters / model no. 7030 (square power switch) 3. Second re-issue black SP1200 / OPAMP filters / model no. 7031 (larger fader knobs and round power switch)
