I've had my HD500 for about 3-4 months now, and need the unit to cover ground identical to your needs.
I have one patch that has a very nice clean Blackface with a switchable chorus and a good switchable 1/4 note delay. Also a switchable O/D and Switchable Lead Distortion.
I Switch off the O/D and Dist., switch on the chorus, and save it as my #1 patch on the bank. (I use foot switch 1-4 for effect switching, and switch 5-8 for patch switching) That is my Clean Patch
I switch on the O/D, and switch off the Chorus, and save that as my #2 patch. That is my Crunch/Rhythm Patch with a switchable Lead Dist. effect.
I use the same patch with a 1/16 Delay instead of the 1/4 Delay for doing mandolin-type trill picking like "You Deserve" by Hillsong
. Then save as my #3 Patch.I use the #2 Patch again with the O/D & Dist. switched on and the 1/4 Delay set with High Mix and Short Repeat along with a Dotted 1/8th Delay Set with
a Lower Mix and a long repeat. (This gives that galloping sound of a Dot 1/8th) Then save as my #4 Patch.
All these give me a Clean, Crunchy Rhythm/Lead, Specialty Delay, Dotted 1/8th Patches on Footswitch 5-8.
Since to-date I don't use any patches utilizing dual amps. I don't need to cover any metal type of tones.
I haven't run into any real world patch creation that I couldn't make because of DSP limiting.
With one amp, I can stack most anything into the signal chain with no problems. I don't have a problem with the buttons either
so I don't really have a use for the 500X right now.
When I started playing on this W/Team, I had only an analog pedalboard and a mic'd 15w Tube combo. I was told "No Amps" too.
So far, I'm about 50/50 about which is better for this venue, but in making everyone happy including myself, the HD500 Rocks...
If the price were the same for both units, I'd definitely get the newer model, of course, but I think The HD500 should be a bargain about now...
