The PreSonus TubePre V2 offers recording enthusiasts a very unique recording experience. The TubePre V2 features a 12AX7 tube output stage separate from the preamplifier stage, allowing users to dial in the perfect amount of tube saturation on any source. A variety of tone shaping tools like a phase reverse button, phantom power, hi-z button, and 80Hz high pass filter are easily accessible on the front panel. We can't forget to mention how cool the Backlit VU meter is as well. This is a single channel interface, use your input wisely!
