GSi Phaser Factory is a versatile phase shifter effect in the likes of some famous guitar pedals such as the Phase 90, the Small Stone, and stuff like that. With Phaser Factory you can create your own phaser and even try to "clone" an existing model. Select the number of phase shifting stages, from 1 up to 20! Set the LFO width and offset. Configure the feedback chain, the output mix and the summing stages. The algorithm is simple and efficient, once you get the perfect vibe, save your presets. And if you're a plugin developer, you can even export a C++ Class that you can use in your project to play the exact preset you've created in Phaser Factory. Phaser Factory is not only a phaser, it's all of them.
