Two Tubes With Lots Of Power

The UA Solo/610 gets its signature sound from a 12AX7 and a 12AT7 tube. The microphone impedance is switchable, allowing you to use these tubes to generate a Maximum Gain Mic Input of 55 dB at a 1.6K ohm input, and 60 dB at a 450 ohm input. Using the DI input, you can plug in an instrument and dial in up to 37 dB of gain.

A Whole World of Tone Between Two Knobs

The SOLO/610's Mic and DI inputs both run to the Master Gain and Level knobs on the front panel. You'll likely discover that the majority of your tonal crafting happens here. As you ride the Input Gain to move from crystal-clear tones into more complex tube transients and crunchy distortions, you can adjust the Level to control how hard your output is hitting your mixer or digital recording interface. The strength of this signal will determine the response you get from whatever processors or FX you have running read more in your chain after the SOLO/610.
