Yes I agree here, to use an attenuator shrinks the life of your AMP mostly and can also end bad on some AMPs,
it is always better to go for 2 different Solutions when you wanna have Tupe AMP and playing it at Home and at the Same Time on Gigs,
in respect of course you do not play your AMP at full potentional at Home, then there might be some Tube AMPs hitting both senarios
or you mean by Home your shielded cellar or garage then there are options.
He got already the Vox AC10 and a Danelectro Honeytone N-10 as far as I can see, he might go for the AC10 at home and get a bigger AMP for the Gigs in large Halls only,
There are a lot of ways he could go for, there are too less Informations, you can fail in some Point when giving recommendations, because of the lack of informations.
He also said we can recommend something different without a hint, he does not say it can be also a Transistor, or in Sound very different, there are too less Informations of what he wants to go for and his needs, also no information of the sound he is looking for or if he does searching for a different sound due to his AC10, also no Information of what field the AMP should be good at, cleans, gain, high gain, pedals, transport, combo, Head, Transistor, Tube, Budget, .....there is a lot left to know befor giving good recommendations.
