Modified schematic to use bemf from both breakers (rs) to charge supercap connected in parallel to bttry.
From 1.5bttry it runs for hours with little voltage drop (0.02v/24hrs); from 6v bttry it runs for days.
Seems very economical setup, but, alas, not self-charger...
thks, love guitar too...
sound of running magnet motors are music to my ears too...
cheers
