Tremulus Lune clone with fotswitchable settings

[RomanS]

Just want to show off my latest build - a clone of the Tremulus Lune circuit (an opto-couple tremolo, in case you're not familiar with it).
The original Tremulus Lune has pots for controlling various trem paramaters (wave shape, wave spacing, ramp up/down) - since I don't need those for live use, I tested the circuit with trim pots, and then used fixed resistor values determined that way).
Unlike the original, mine has two footswitchable settings for space/depth, though - so I can choose between a classic deep/lush slow tremolo, and a fast/shallow Leslie-like flutter...
