Roland AF-60 BeeGee

I personally enjoyed the AF-100 BeeBaa design a lot, so once i noticed that this existed - i just had to draw it up. Slave to my own habits, i "modernized" the transistor pinouts to match those everyone have in their drawers. Original has 2SC1000GRs in them, so your usual suspects should work just fine in there - 2N5088, 2N5089, BC549, BC550, MPSA18 and so on. The opamp in the original unit is metal can version of TA7504 - which is very close to LM741, but you should be able to get it right with almost any single opamp.
