Before we touch on inner workings and other details I would like to share the motherboard assembly excluding the enclosure so its easier to refer to particular functions.
A view of the outside connections. The small jumper between the R-OUTPUT (DRY) and the L-OUTPUT/MONO (WET) is just a bridge between those two so the L-OUTPUT/MONO can be used as a MONO (mix wet+dry).A couple of functions are open and are used for future developments.
In this working configuration there is one guitar input and two outputs assigned to guitar out dry and guitar out wet. A small jumper is included so the left output can be fully used as a dry+wet output. There is space allocated for additional tape artifacts including two extra dials.
Here is another enclosure to show the minimal size requirements being 4.4″ x 3.4″ x 1.0″ 88mm x 112mm x 25.4mm(inner dimensions)
