Not long ago, I started using stompoxes in lieu of my beloved rack gear. I discovered new ways of mixing a common effects device (ie. delay or reverb or solo boost) with several patches in my TC Electronics Nova System and it got me thinking.
I knew the Quad switch worked with various FX in the MP-2, but I wanted to use it with my MP-1 Classic as well. Then, I discovered midi control commands - specifically, I could control any effect in my FX device using the control number of the Quad switch. So, I can add a solo boost to any patch. I can turn the delay or the chorus (or the flange....) on or off for any patch. I can switch the octaver on/off for one patch in particular....you get the idea.
Why didn't I realize this a long time ago?
So, I ditched the Nova System and went back to the MXC pedal for my MP-2 and my MP-1 Classic. However, now I was armed with the full capabilities of the Quad switch at my disposal, running my FX device (Boss GX-700). I use it to control the EQ for a solo boost (most times it's just a flat volume boost), toggle individual F/X, or just mute the sound and use the onboard tuner. Here's a graphic to illustrate how I have arranged my patches.
