G taper pots vs W Taper pots, Ibanez Renometer musings

[TheBigMan]

Hey all, long time no post. 

Recently I've dug my old Ibanez No. 95 Renometer out of the cupboard.



It's probably the best sounding EQ pedal I've ever used, being broadly like a parametric rather than a graphic EQ in usage but also having switches for boost and hi-boost.  Of course, nothing is ever perfect and there are 3 fundamental issues with it.

1. It's enormous, takes up the space of about 2.5 compact size pedals on a board
2. It use 2 x 9V batteries for a bipolar power supply, no DC input
3. No bypass switch or footswitches for the boost options.

I've been thinking for a while about trying to build a clone of it, the circuit is actually quite simple and the only even slightly awkward parts are the inductors which I can get.  Other than the pots, I can't find 20K G Taper pots anywhere, with or without center detent.  W taper seems to be pretty common, with both tapers being (as I understand it) reverse audio to the center, but G taper is linear from center to full and W taper is log from center to full.

Any issues that anyone can see with this other than the pots will be less sensitive than they should be?  Has anyone attempted a clone of this pedal, or the GE-500 which appears to be broadly the same pedal?

Could of course just use a TB box with it, but that's even more space on the board, and besides, where's the fun in that?
