They are a great amp and the Boss Tone Studio software enables you to program the channel presets. If the amp has the Version 2 software installed you get four effective channels CH1 and CH2 then press and hold the PANEL button which gives the two additional channels on the CH1 & CH2 buttons. I have mine set up to give me Tremelo, A Twelve String, Shadows sound using an external pedal, and Shadows using the inbuilt echo, this together with the setting on the Panel (whatever you have the dials set at) provides me with all I need for the gigs that we play.
Here's a couple of sample videos, I altered the sound using the inbuilt GE10 graphic equaliser at the end of the second video, and used my other strat as well
If you need any help just shout, not saying I'm an expert, but may give you a heads up on the way to go.
