Thanks. Checked the Speck ASC. It too uses antilog pots for the
frequency controls. Single gang 500 k for the low and high bands
(simulated inductors), dual gang 50 k for mid bands (SVF).
They're 9.5 mm wide plastic boxes with knurled shafts. No brand
name.

This thing is seriously expensive for what it is, by the way. Two
TL074 and half a dozen 5532. The only non-jellybean component in
it is a polystyrene cap. I sure hope those pots will last longer
than the Piher trash in my Rocktron...
