Ribbon Cable - Flexstrip, 4 Conductor
Four conductor Flexstrip ribbons cables. These ribbons feature a nomex insulator so there are no melting issues when soldering. Unlike typical ribbon cables, the wires are designed to distribute the stress of the bend and vibrations throughout the entire cable rather than directly on the solder joints. These cables are a great choice for PCB to PCB connections in pedals, synths, and other electronics. The spacing is .1" (2.54mm).

Op-Amp - LM358, Dual, 8-Pin DIP package
LM358 dual op amp in an 8-pin DIP package. These devices consist of two independent, high-gain, frequency-compensated operational amplifiers designed to operate from a single supply over a wide range of voltages. Operation from split supplies also is possible if the difference between the two supplies is 3 V to 32 V (3 V to 26 V for the LM2904), and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is independent of the magnitude of the supply voltage. Applications include transducer amplifiers, dc amplification blocks, and all the conventional operational amplifier circuits that now can be implemented more easily in single-supply-voltage systems.
