BlueTube DP v2
A dual-personality preamp with an amazing variety of tones.
Compact, affordable, and capable of a stunningly wide range of tones, the BlueTube DP V2 dual-path mic/instrument preamplifier offers two independent channels, each with an XMAX Class A solid-state preamp, followed in the signal path by a 12AX7 vacuum-tube stage. A Tube Drive control provides a wide range of sounds: When clicked off, you’re using the solid-state preamp for quiet, transparent amplification; when engaged, your signals flow through the tube preamp, and you can achieve anything from gentle warmth to edgy distortion. Equipped with instrument and mic inputs and built tough for serious gigging, the BlueTube DP V2 is a great choice for guitarists, bassists, singer/songwriters, and more.
