Shame about the AC30. I bought mine used in 1979 and it hissed like a kettle until you rolled the cut control down (this was a top boost reverb version with greenbacks). TBH I always found it a rather dry, brittle sound until it was running around half volume, by which time the first 2 or 3 rows in front of you probably had hearing damage. The model with blues was sweeter, but even louder, and keeping volume down while getting a decent tone was a constant battle.
I remember coming off stage when I was 19 or 20 with the world sounding very distant, and struggling to hear people at the after-gig party someone threw for us (first and only time!). It's now sat in our cupboard under the stairs, and will need recapping because it's not been used in 20 years. Ended up building my own amps as a way to get the sounds I wanted at sensible volumes.
It sounds like you have a wonderful gear collection. I didn't really start collecting stuff until about 20 years ago, by which time I'd already missed most of the bargains. Still have the Coloursound Fuzz that I was given for Christmas, aged 17, and the Crybaby (no longer working).
I went through a period using a Godin xtSA to control a Roland GR33 synth module. It was a lot of fun watching people trying to find the sax or flute player in the band. I still have it, but the kit isn't reliable and hasn't been out for a long time.
