Same. Absolutely loved that cab. I had the 4x10 to 'match' but used the 1x15 for most things. mid 90s to mid 00s.
The Trace cabs sounds far superior, tone wise, in that video. It will give up volume wise because it's an old 1x15 that was no doubt rated for lower wattage amps.
If a manufacturer can design a 1x15 cab with that high mid/treble detail, but to handle say 400W and be as light as possible, that would be great.
I later had the Orange 4x10 and 1x15 setup with the AD200b Mk3 - sold that years ago. The 1x15 was fantastic, again.
