This pedal gives you the ability to access 33 different saved patches and access to the loop setting on the id core 150 with ease, plus With the FS 10 that comes with the id core you get an extra t2o buttons that allows you to turn off and on amp modulation and delay.
For a live performer using a id core amp this pedal is necessary in my opinion, tho does come with some faults, such as switching between channels can some times fail due to the Switches being a little small and swapping banks can be frustration because if you Don't hit switch A+B or B+C at the exact same time it wont change banks.
In all this pedal is a necessity and definitely gives me easy access to all the features the id core has to offer tho its a little on the pricey side
