Last night I was doing a gig using a Spider 4 (75) with a Fbv Express Mkii. In the middle of a song the amplifer started looping, playing stuff I had played seconds before.
Now, I didn't touch the amp so I must have pressed something on the Fbv Express Mkii with my foot to started the loop.
Does anyone know how one starts a loop like this using the Fbv Express Mkii? I want to know so that I can make sure this doesn't accidentally happen agan.
