The Universal Audio Solo 610 pre-amp is a portable single channel version of the classic 610 preamp. Featuring input and output gain, instrument DI input, hi and lo-z switch, phantom power, lo-cut switch, and DI through.
The Solo 610 is a smooth, rich pre-amp, and brings to mind what you would think of when you think tube gear. While maybe not as defined or extended in frequency response as a Neve or Great River it can be the perfect match for certain sources or microphone's particularly vocals and ribbon's. Also works great on bass allowing you to dial in some grit with the gain controls. The instrument throughput is also really convenient when tracking bass or electric piano in the studio and has made it my go to DI box. The multitude of switches allow you to dial in just the right sound and go from line in, to mic, to instrument with ease. The ability to send mic or line level signal along with the previously mentioned throughput would also make it a great option for bass/keyboard players live setup giving you flexible and convenient control of both your amp and DI sound. Not to mention giving the studio engineer a wide variety of options to experiment and create different sounds from smooth tube's to fuzzy distortion.
The Solo 610 would be a great addition to just about any studio based on it's portability, flexibility, and quality and would also be a worthwhile to check out for most bass or keyboard player's setup's to add extra control and depth to your sound in situations where you need to DI. The price also makes it attractive for smaller studio's where a couple hundred really makes a difference.
