Im trying to track down one of these units to use for DI Bass (straight to FOH). The reasons for these: 1. Models and FX in one package. 2. 2u is big enough so no X3's. 3. Im confident with Line 6 stuff, heard some nice tones from the Bass Pods. I know I could get a XT Pro (guitar) easier but I would have to make sure it has the Bass Expansion pack. Besides, Black will match my HD Pro . I haven't completely ruled out the X3 as its newer, has expansion pack and has dual amp capabilities. Just trying to keep size down. Im struggling enough to get the HD POD Pro so getting 2 (one for bass) will be a battle. Also, I havent heard many demos of bass tones from the HD. Any advice?
