The board I'm tapping into exists physically inside a digital
"modelling" guitar....I've made a small circuit board to sit inside the
guitar too, but I need to tap of the main guitar cct board to feed off
to my board...the only way of doing this is to either solder some leads
onto the existing cicuit board (very fiddly & potential for
shorts/breakages) or as a preference piggy back an empty IC socket on
top & then i can insert pins into this to tap off the necessary pins.
