Well that answers that lol, mines the standard , not the XL or Plus, so only the plus will allow you to add a cab and run the 2 together, that sucks! Used to have the XL, your right it's heavy as you like ha ha! Am I right in thinking I can plus the pedal board I have into any line 6 and run it three with the saved patches! May as well buy a larger line 6! Iv only ever had a Flextone III And swear buy it, just looks tiny on stage hence wanting the extra cab!
