If you are shopping for an amplifier head, there are some important things to keep in mind. Amp heads have exploded in popularity over the last couple years as we've seen a surge of new "portable" heads like the extremely popular Mesa/Boogie TransAtlantic TA-15, Vox Night Train, and Orange Dual Terror Head. There is also a lot of buzz around the electro-harmonix 22 Caliber compact amplifier head, and the Vox AC4TVH. And obviously there are lots of great traditional choices from heavy-weights like Marshall, Randall, Vox, Peavey, etc. Be sure to look for features like number of channels, wattage (power), how many modes, half-power switches, reverb, voltage control, switchable rectifiers, footswitch options, tubes, built-in effects, etc. These can all give you more options to shape your tone and creativity. We encourage you to check out the reviews on these popular models and see which amplifier head is best for you.
