DIY: bass-boost on a pimeta

this layout had to map and match to the mainboard, below. those blue R's are on IC socket pins (removed from a socket strip). the R can be trimmed, changed, etc - and there are similar pins on the mainboard, for this to mate to.

 

the wire leads come direct from the capacitor on top of this perf-board. these 4 leads complete the electrical circuit and also provide some suspension (physically) for the circuit.
