My two cents,
The HD500 and the DT50 are a great live sounding rig, and the HD500 into a computer sounds good also,
but the best sounding and responsive guitar amp sim software for a DAW is Scuffham Amps, very responsive
and analog sounding. I use it as a standalone or recording into Pro Tools thru a Focusrite Saffire Pro 40.
is really reasonable, around $100. plus you can try it for a 15 day trial.
If the HD500 era ends, I will still use it live, it serves my needs. But will still look at Line 6. As they have one of
the best amp modeling setups for live. I was going to look at getting a JTV, but will wait to see what Line 6 brings
next.
No, I don't have a lot of extra cash sitting around, but I have a slight G.A.S. problem.
Anyway, just some thoughts.
