I gots the one from DVM .. and I love it.. will answer in more detail tmrw.
Twas late last night and wanted to give you the answer this amp deserves. When I got this amp, I was searching tonewise, and wanted to play what I was hearing in my head. I'm much, much closer because of the TA-15.
Its an amazing amp, three power modes, 5, 15 and 25 watts, three amp styles, Vox Clean and Top Boost on one section, Fender, Marshall and Boogie on the other. A cut switch that works like the cut on a Vox AC30, reverse and eminently usable on a pull switch that doubles as a master volume for channel 1. No Mid eq, just Bass and Treble, but strangely, I don't miss it (yet). No effects loop or reverb. A Strat through the Tweed setting on CH2 is divine (humbuckers sound great too...), the Marshall setting on HI1 is tighter than you would expect from a JVM Marshall head and the HI2 (Boogie) seems softer than what Mesa is known for. This won't get you into Godsmack territory without a pedal. Having said that though, it responds to picking dynamics and guitar volume control, sweet, melodic and very organic. Its like having 3-4 amps in one hand held tone dream. Small to medium clubs, this amp parties all night.
I built a 1x12 thiele cabinet for it, you can get details
here. (Please forgive the wire animals...)
Alone, this amp sounds awesome. Add your favorite pedals and you're in a whole new dimension.
I designed my pedal board on this amp, and it sounds really close to what I want. Its a great amp to take to the studio, since there's so many tones in this box. Did I mention the awesome blue glow? Its impressive on a dark stage. I've played Maiden to RATM to Mayer to Journey on this, all with compliments on the tone. The other guitarist in the band stepped up his game because of this amp.
The best reason I got this was to avoid lugging a 2x12 box around. Guitar like a backpack, amp on the shoulder, cab in hand, pedalboard in the other...one trip.
Need an effects loop and reverb? Go TA-30. Small, powerful and great sound? TA-15. Hope this helps.
