16mm Solder Lug pots:
If you want to build the Aquababy with modulation like I did (see my build pic later in this doc) this is the dual pot I used:

R35 is not used on the DM-2, but some analog delays do use a resistor there. Supposedly it can improve the THD from
the compander although I have yet to hear an actual difference (perhaps it’s only be detectable on a scope). In any case,
if you want to try it yourself, use a 20k resistor for R35. Otherwise just leave it empty.
Like the Aquaboy, you can run the Aquababy at 15v, but it might be very difficult to fit a charge pump in such a small en
-
closure. If you intend to run the Aquababy at 15v, change R13 and R14 to 36k from 10k.
