WA-MPX is an authentic reproduction of the most revered microphone tube preamp that ushered in the birth of rock 'n' roll and radio-ready hits. During the golden era of tape recording, this type of vintage tube preamp became the signature sound of many hit songs, including Elvis Presley, Kurt Cobain, Les Paul and Bing Crosby.
Today, this is still a sound sought after by many great artists.

With top-quality components, a true-to-the-original circuit design and adjustable tape saturation, the
WA-MPX authentically reproduces the analogue sound of the original to add warmth and colour to any signal.

Hand-assembled with three premium tubes per channel, paired with custom-wound USA CineMag transformers,
the WA-MPX and WA-2MPX authentically reproduce all the analogue sound of the original.

Power and versatility for a wider range of analogue sounds:
Thanks to a high tube voltage of 300V and a tube gain of 90 dB, sufficient power reserves are available for a wide, open basic sound. If the tubes are driven into saturation, natural harmonic distortion and compression are created.
With the "Tape Sat" circuit, a purely analogue tape saturation emulation is also on board.
WA-MPX and WA-2MPX offer vintage sound and modern connectivity for use in any studio or live rig.
