I bought the 3.0 8T five-six years ago, and about a year later was able to buy a 10t cab. also with the shuttle saddle built in.
What a GREAT little combo. I almost always use the 10T, but have kept the 8T for vacations or bedroom use.
I play a lot with singer/songwriters and light percussion, and the 10T does great in that context. Have used it with two guitars and drums, and worked fine in a small space and the drummer playing with restraint.
The cabinets are smartly voiced to the amp, and that little amp is a gem. In a pinch, I once used the head with a 4-ohm cabinet, and was very satisfied.
Let's see if either of the GB brain trust now develop a successor through their current endeavors. I don't think there has been anything on the market that is close to these combos, at their particular balance of performance quality, size/weight and price point - there is pricier stuff, like from AER, or heavier stuff, but these were unique. Congrats to the OP for scoring one.
