This little PCB makes wiring a DPDT mini toggle switch up for phase reversal easy. Most standard DPDT mini toggle switches with flat solder lugs will fit perfectly. Then, it’s just a matter of connecting your signal input and output, and when your toggle switch is flipped, the phase will reverse. This is a much more elegant solution as opposed to soldering insulated wire across switch terminals. Overside wire solder pads make connecting a breeze. Ideal for use in guitars, pedals, and any other DIY audio project or mod. Analog Classics PCBs are manufactured to high-quality standards.
