Another amazing EQD pedal! The Rainbow Machine is very unique, and if you are reading this, you've probably heard some sound clips. If not, go do that - I can wait.
Now that you've heard it, I'm sure you're all like "how can I use this as a normal effect?" Well, by virtue of the tracking knob, you can turn this thing into a modulation device, or a delay pedal, with varied results. As a bass player, I keep tracking very quick and the pitch close to center - this gives a really wobbly sound that I use all the time. You can make it subtle or.... not. The magic knob is always close to 100% on for me, so that when it's time to turn some heads, I just have to press one footswitch. Try one out for yourself and see if you can tame it - there is a whole world of cool sounds waiting for you if you do!
