Lets you make your smaller amp bigger, or just play through your preamp!
The Tech 21 Power Engine 60 is an open-backed, 1x12" powered extension cab designed to match and complement the Trademark 60 combo. It features a special-design speaker, level control, 3-band active EQ, 1/4" input, and balanced XLR input and output. While not a standalone piece, it can be used with any discrete preamp. You don't have to tweak your presets. Just plug into the Power Station and you have your sounds.
