This modelling amp is controlled by !n app that is no longer available on app stores, but can still be installed using the instructions from line6 - https://line6.com/support/page/kb/legacy-products/amplifi-products/ampl/amp...
It does have 4 preset amps linked to the front selectors though so can be used directly as is with the effects on the knobs on the front.
Great for guitar practice.
