Well I've dived in feet first and ordered an Aguilar TH500C head from GuitarGuitar which says it will get them in stock within 2 weeks. I've also ordered a Barefaced Compact with vintage silver cloth grill, so these two will comprise my 'rock'/non-DB rig.
I hope this puts an end to my rig search! It certainly ticks the boxes for me - lightweight, compact/manoeuvrable, powerful, clean-through-to-warmth, ability to overdrive (so don't need separate pedal) etc ... and it looks pretty cool too, which always helps
