Tom Oberheim SEM Pro

Bought it used , the synth looked like it had lived, the signature almost gone, side scratch, after a year owning the filter knob wasn’t working the same, I sent it to Tom Oberheim himself to fixed it and he did, working really well,  i need to sale it to buy other gear with it as this is my only analog synth and would like a bigger palette of sounds. I can send you pics of the email of Tom Oberheim, also i can make a video if you wish.i am still hesitant of saling it so offer is firm .
