The Bender is an offspring if the big Tonebender family. He produces a wide range of warm fuzz sounds. Its tone control makes it even more flexible.
Like its ancestors it uses a positive ground, so you have to use a seprarate power supply or battery.
The pcb dimensions: 46x33mm. It is professionally made, all holes drilled including silk screen.
