The manual for the Digitech Trio pedal has the following information...." Guitar FX The TRIO provides built-in guitar effects which can be turned on and off using the GUITAR FX button. The button has 3 states, they are: • LED Off - The guitar effects are not enabled. • LED Green - Indicates that a rhythm guitar effect will be used for the 'Learning' and 'Playing' states. • LED Red - Indicates that a rhythm guitar effect will be used for the 'Learning' state and a lead guitar effect for the 'Playing' state. The type of effects added are dependent on the genre selected."..... Can anyone explain specifically what types of 'effects' can be added in each genre?
