I am a noob with these amps. Without the ipad and without a pedal pressing the tone button gives me ABCD from bank one. Is that all I can access without extra equipment? i.e I cannot access bank 25 with downloaded tones? I can edit the tones in bank 1 , but not replace them? If I edit the tones in bank 1 until they sound horrible , how do I recover the original sounds (factory reset?) Thanks.
