I sold a ton of stuff (maybe literally) to make the move to L.A. so I didn't sell anything in order to buy the Axe II.
But once I got settled here I was ready to get a new rig but I was undecided between the Axe and a new Mesa MKV combo. The Axe won and now I give up most of my free time!
The only other things I can think of that I'm giving up are carrying heavy, bulky amps, needing extra storage space for those amps, and worrying about my bad back when trying to lift them up. Oh, and I gave being limited to a few amp channels, buying more rack FX units, patch bay, rack cases, cables.
Oh, yeah, I gave up on needing a van to transport my gear too.
And if I ever find that POD 2.0 that I bought some years ago I'll give that up, although I guess I already did... hmmm... where is that thing?
