I have the 30 1 x 12 combo, not the 15. I bought it for the red channel sounds since vox isn't really my cup of tea. Turns out I just needed to play the right vox circuit. Cripes that green channel sounds great. It's just so right when dialed in a little crunchy. The tweed mode is a great clean sound. For my needs it is really easy to dial in. The H1 and H2 sounds are good, but I don't use them a ton. I like the H1, but it doesn't seem quite as brash as jmp/jcm drive sound...but the combo speaker could have a lot to do with that. It feels more JTM45-ish if I had to pick a Marshall to compare it to. All of the models except the tweed definitely need the master up at least 1/3 of the way. The master is pretty good in that there is actually a change in volume over most of the range. IMO the TA-30 has enough juice for home and gigs with good PA support, but I wouldn't mind a higher wattage model honestly. Some jams I wish there was some more headroom...but I like really loud jams. Oh and it's crazy portable too... Size and weight are very reasonable. The price is unreal too. Just a great great value.
