Tube or solid state? It's got both!

The PreSonus BlueTube DP Stereo Preamp is among the most versatile two-channel mic and instrument preamps in its class. Its Dual Path technology lets you choose between two preamp stages: a transparent solid-state or warm tube preamp. Each gain stage of the BlueTube DP is pure Class A with high headroom.

Each channel of the BlueTube DP includes a -20dB pad, polarity reverse, 80Hz filter, and +48v phantom power. On the front panel you'll find controls for solid state gain and switchable on/off tube drive. When the tube drive is off, the tube preamplifier stage is bypassed delivering ultra-quiet and transparent solid state preamplification.

Large analog VU meters provide precise visual monitoring. Dual Neutrik combo jacks for microphones or instruments provides quality I/O and make the BlueTube DP great as a DI for electric bass and guitar.

I bought the BStock version, and the tube preamp on channel two does not work. You have four preamps to choose from (solid state and tube on two different channels). Channel one is great. The solid state side works on channel two, but they should not advertise a BStock item as wholly working if you're gonna drop a buck seventy on it only to not be able to return it. Don't buy this preamp. Go with the ART tube pre. It's sounds way, way better.
