The Mesa Boogie Transatlantic TA-30 guitar amp head offers up an inordinate amount of tones and textures in a compact, road-ready package. Two footswitchable channels play host to a broad 2-band EQ, independent reverb and FX sends, and can be tweaked through five different modes -- two on the cleaner first channel, three on the higher gain second channel. The power section is where this amp really stands out. With Mesa Boogie's patented Duo-Class and Dyna-Watt technologies, you can switch between different wattage and operating class settings on a per-channel basis, letting you choose exactly how much headroom the output stage has as well as clip characteristics for power tube breakup.
