As requested. I happen to have an original unit in metal enclosure, and to my ears this is definitely one of the greatest Ibanez overdrives. This layout is with your standard transistor pinout and with input buffer omitted. Reason for omitting the buffer is quite obvious... It is big, but should fit in B-box without an issue. Clipping diodes are placed so that one can easily add a switch for them. I would personally probably go with two red LEDs and two (or four) 1N60Ps.
Edit: There were a few errors on the layout (transistor labeling, vref via 1M to wrong input, HF tamer cap location and a vref via 100k to discrete opamp). All of those are now fixed and the current layout is verified. A/B'd this circuit with my original unit, and the differences between the two are minimal. Still one of the greatest Ibanez overdrives!
