The Triple delay by TC Electronic is a great peace of gear. Pros: Great sounds, parallel mode, awesome tone prints, and you can adjust your own delays and you can decide to each knob the function, for example there are no feedback knob on the unit, so you can change the function. This way you can add the parameters to the expression pedal and go crazy . . . That was my main goal and I did get that. Lot of funs and ton of options. Cons: you have to paper tape the switches , or you will forget what you stored on the presets. You can't use the expression pedal for all the delays, just one at the time, and you must choose with the delay engine switch, in the middle of the unit. That switch is small, it's hard to read the text if you're standing, so practice and double check the position. Ofc you still have many-many options. Setting the expression pedal was bit of challenging, cause the are just few info videos, and description how you can do that. Cheers
