wcmexbm, I hear you brother.
For mr the new HD models have no soul. Every time I'm in a different store I demo the HD line and nothing I hear makes me want to buy one. They just don't sound good.
But the X3 sounds great and way better in not only my opinion, but others as well. Great sound and lots of amp options for guitar and bass make it an easy choice. And the POD 2.0 has a few sounds that the X3 or HD PODs can't even touch. That's why in my studio I have 2 original PODs, a POD 2.0 rack, and an X3.
Since you have a good ear for tone I recommend trying the Zoom G5, or maybe the MS100-BT as something to add to you setup. I'm not saying the amp models are better than the X3. But what you would gain is the ability to call up , for example, 6 delays or choruses, or 3 dual band parametric EQs. The Zoom units are great for tone shaping.
