Preamps

The 710 Twin-Finity Universal Audio is a mic preamp / headbox that subtly combines the heat of lamps, and biting transistors. The 710 has a dual gain / gain stage control that can vary the amount of coloring and distortion dramatically, allowing you to push the input gain as you a guitar amp. The VU meter has a unique "Drive" mode to see how much you saturate the input stage. You'll be able to easily record guitars, basses or keyboards with the high-impedance Hi-Z instrument input on the front panel, and mix lamp and transistor sounds for a multitude of textures and sounds. sounds.
