Re: Jet City or Legacy 212?
I agree with the previous post, even a JC 20W is way too loud for an apartment to get decent tone out of. I would recommend something like a Yamaha THR10 for apartment use, one of the best sounding modelers I've played. They have a 100W version, which would still sound good at apartment levels, but again, it's a lot of amp (and $) for that.
I rent a small house and a 20W tube amp is a too much in it, I use an AMT pedal preamp through an AMT TC-3 power amp into a 1-12 cabinet at home. Heck, even with that 3W power amp I never turn it up more than 1/4, I've even used that power amp running a mic'd cabinet at church. I have a ISP Stealth 180W power amp, but I rarely use it.
And yeah, especially at low volumes SS can sound as good as tube. There are some 5W tube amps out there, but even those can get pretty loud for an apartment, at that point it may depend on your neighbors ;-)
