The new Triptik 2 will feature a front panel switch and 3 color indicator for changing channels like whats fitted to this SD-60. Each press of the button loops through the channels. Once a foot controller or MI-01 midi converter is attached, the front panel switch is deactivated but the 3 color LED Indicator will still display the selected channel. The amplifier above is a modified SD-60 'Stevie Dacanay' model with the front panel switch and the Auto biasing circuit that I did for the owner . He just happened to make the suggestion and I thought it would be a good idea to use it on the new Triptik 2 model.
