Equipped with instrument and mic inputs and built for serious gigging, the PreSonus® BlueTube DP V2 dual-path mic/instrument preamplifier is a great choice for guitarists, bassists, singer/songwriters and more. Compact, affordable and capable of a stunningly wide range of tones, the BlueTube DP V2 offers two independent channels with combo mic/instrument inputs and unbalanced ¼-inch and balanced XLR line outputs. You can use it as a preamp and as a direct box (DI) for guitars and basses. Singer-songwriters can run the vocal through one channel and a guitar through the other, feeding both to the PA - no guitar amp needed.

Each channel features one of PreSonus' famed XMAX Class A solid-state preamps, followed in the signal path by a 12AX7 vacuum-tube stage that's hand-selected and carefully tested for top audio performance. When the Tube Drive control is clicked off, you're using the solid-state preamp for quiet, clean transparent amplification; when engaged, your signals flow through the tube preamp, and you can achieve anything from gentle warmth to edgy distortion.

We didn't forget the extras: an 80 Hz highpass filter, phantom power, a -20 dB pad to control hot input signals, polarity reverse and a backlit VU meter. Housed in a rugged case small enough to carry in a gig bag or screw-mount in half a standard rack tray, the BlueTube DP V2 is a great-sounding tool you'll use on a variety of sources.

1. The Iconic Analog Sound of Music's Greatest Recordings

   The WA73 & WA273 recreate the most iconic British console sound made famous by legendary recordings from the 60s and beyond. Known for delivering rich, full analog warmth, the original became the foundation of classic rock and was the centerpiece of countless timeless hits. The sound of those famed console preamps can be heard on recordings by The Beatles, U2, Kendrick Lamar, Led Zeppelin, and many more.

2. The Perfect Balance Of Natural & Polished Sound

   The WA73 & WA273 deliver the perfect balance of “unmistakably analog” tone & clarity that every engineer is chasing. With 80 dB of gain and a discrete Carnhill Transformer balanced signal path, the 73 series delivers the unmistakable sound of the original British console preamps. Featuring hand-wired construction using premium components that all receive dedicated individual testing in Texas, the 73 series delivers the necessary quality to upgrade your sound to studio-grade.

1. Tape-Era Tube Warmth

   The WA-MPX & WA-2MPX are authentic reproductions of the most revered microphone tube preamps that pioneered the birth of rock ‘n’ roll & radio-ready hits. During the golden era of tape recording, the original 351-style tube preamps were the kings of studio tech delivering pure analog warmth; the signature sound in the signal chain of hit recordings for artists including Elvis Presley, Bing Crosby, Les Paul, Nat King Cole, and Roy Orbison.

2. An Authentic Vintage Experience

   The WA-MPX preamps deliver the same sonic signature as their vintage inspiration, imparting high-headroom analog warmth that goes from ultra clean to rude and saturated. Each channel boasts a handwired circuit containing custom CineMag transformers and three tubes that, with the high-gain switch engaged, bring the WA-MPX up to an incredible 90dB of gain. The WA-MPX not only delivers the sound of a legendary tape-era tube preamp but one of the best values in an all-tube mic preamp on the market today.
