A bit confussing isn't it?, you've been recommended
the BOSS GT3, Johnson J-station and numerous amps. Just before I answer the question, no way does the GT3 blow away the POD. I was going to get a boss multi-effects, so glad I didn't. Just a bunch of effects (tacky shit like auto riff and that-just a cheap gimmick). The POD delivers a almost any tone that you could imagine you just have to work with it. It blows the J-station away though the J station does have a few bass patches if I ain't much mistaken.
I bought the POD pro (rack-mount POD version), played into it and listened through headphones (as you can have it any volume you desire). That isn't practical though is it. I then bought a tube amp and the floorboard (with wah pedal, volume pedal and footswitches to control the POD-ideal for live situation. I therefore now have a unit for direct recording, general all purpose at home and practical for live use, delivering not a bunch of effects, just great tones.
Anyway back to your question. I would buy
a VOX cambridge 15 or 30. These are relativley cheap, low wattage whilst maintaining that vintage sound. These are truly magnificent, I wish I had bought one instead for use at home instead of my Marshall VS265R. There is no comparison, I'm thinking of selling my marshall and buying one of these for home use (even though I'll loose a shit load of money). Don't take my word for it, test them.
This amp would only suffice for home use I must stress. I would not use it live. There is no point really in wasting money on buying an expensive amp for home use. Getting a relativley small amp that you can turn up to high volumes yields far better results than an amp set to 2 or 3.
Alternativley you can buy my Marshall. LOL.
