The Special Edition Engl Preamp features 6 basic sounds and 8 switchable sound options to store in 128 MIDI presets. From crystal clean through smooth jazz, from Texas crunch to pounding rock, from fat metal punch rhythm to screaming leads you'll find all the tonal tastes you need right here. This sophisticated guitar preamp marries the unrivaled tone of all-tube technology to the awesome sound-shaping might of control features powered by state-of-the-art microchip circuitry. This elegant combination puts a vast range of great fundamental tones and an all but inexhaustible reservoir of compelling variations at your fingertips, all of which may be controlled remotely via MIDI. What's more, the Engl preamp boasts a host of hip and practical features, including a switchable noise gate for the Crunch, Lead I and Lead II overdrive channels; frequency-compensated stereo out featuring 4x12" speaker cab emulation. You can send a balanced signal to a mixing console via the XLR ports, or an unbalanced signal to a recording device via the stereo jack.
