GCB-95 latching switch. This is a large double pole double throw (DPDT) effect/bypass switch for MXR and Cry Baby pedals, featuring the Dunlop “D” logo.

Eight 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).

LM358H dual op amp in an 8-pin TO-99 package. The LM358H series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifiers, dc gain blocks and all the conventional op-amp circuits which now can be more easily implemented in single power supply systems.

PT2399 echo/delay chip used in many DIY and commercial pedals. The PT2399 is in a DIP 16 package. Minimal external components are required for use and delay time is set with resistance.

A semiconductor device which passes current in the forward direction(from anode to cathode), and blocks current in the opposite direction.
