The Dual Demon Pedal Caster is a dual stompbox adapter.
Like a lot of these pedal/stompbox adapter things - it's vaguely based around the Ken Stone designed CGS60.
I've added a few features including a pot to attenuate the signal sent to your pedal, dry/wet mix knob, gain recovery control and a bypass toggle, to give you a seamless control over levels, blend and performance.
Black or red panels are available.
Due to the 6.35mm connectors this is a deep one. With the power installed, it tops out at 44mm depth. Should be fine for most skiffs, but something to be aware of.
It's got that sweet, sweet reverse polarity protection too, and will run absolutely fine on reversed power (thank you MB1S bridge rectifier)
This bad boy clocks in at 4mA on the +12v and 4mA on the -12v on my test rig. +5v is not required. Half the circuit is passive...
