...Wishbonebrewwery -- Takaab could work but I REALLY dont like 2hp modules. fingers are just too fat...
-- Scarfmeister

as a workaround i have most of my 2hp modules combined with small blank panels on at least one side.
this particular module does not have any potentiometers so probably there is no need for additional space.

i never have heard of this module but reading the description made my curious - i am going to search for some sound examples...
