With two combo mic/instrument inputs, the half-rackspace BlueTube DP V2 is designed as a preamp for both guitars and vocals. Singer-songwriters can run their vocals through one channel and their guitar through the other, feeding both to the P.A. — no guitar amp needed. It also serves as a DI box, thanks to balanced XLR and unbalanced ¼” outputs, and is housed in a new, rugged, 1/2U case. Try the BlueTube DP V2 as a front end for a DAW too. The BlueTube DP V2 is available immediately; MAP/street price is expected to be $229.95.

Housed in a rugged, 1/3-rackspace case, the TubePre V2 rear panel sports separate unbalanced, ¼” instrument and balanced, XLR mic inputs and unbalanced ¼” and balanced XLR line outputs. The front panel offers controls for gain, 48V phantom power, 80 Hz high-pass filter and polarity-reverse, as well as a mic/instrument input switch. A lighted VU meter and a clip LED help you keep an eye on your levels. The TubePre V2 is available immediately; MAP/street price is expected to be $129.95.
