The MASH footswitch is one the great features of the Brainwaves. I noticed i sometimes have to step hard on the footswitch to get the full sharp bend effect.
Here is a tip you can use to make it more easy to use in Whammy or V1>V2 modes:
Go to the MASH tab in the TonePrint app and modify the course of the footswitch. You can for instance ask the pitch to reach 100% when MASH footswitch is only engaged at 75%.
Certainly the course is shorter but you no longer have to worry about pushing the footswich completely to achieve a full bend.
Hope it helps
My Brainwaves is my first MASH pedal, and I discovered this almost immediately. As I wanted it to operate as a momentary switch, rather than a pressure-sensitive controller, I mapped it to 100% all the way across the board, and map the bend time to the Mix knob.
