Line 6 DT25 Specification

The Line 6 DT25 is a versatile 25-watt guitar amplifier designed in collaboration with renowned amp designer Reinhold Bogner. It features a unique combination of digital modeling and tube-driven technology, providing a dynamic and responsive tonal experience. The amplifier is powered by two EL84 tubes and a 12AX7 preamp tube, which deliver a warm, authentic tube sound. Its power section is switchable between 25 watts and 10 watts, allowing for both high-volume performance and lower-volume practice settings.

The DT25 offers four distinct amp voicings: American Clean, British Crunch, Class A Chime, and Modern High-Gain. Each voicing is meticulously modeled to replicate the characteristics of classic amplifiers. The topology of the amp can be reconfigured on-the-fly, with selectable Class A/Class AB operation, Pentode/Triode modes, and various feedback loop options, giving musicians unprecedented flexibility in shaping their sound.

Integrated digital modeling technology provides access to a wide range of effects and tones, seamlessly merging with the tube signal path to maintain authenticity. The amplifier is equipped with MIDI connectivity for easy integration into complex setups and allows for extensive control over its settings. A comprehensive array of inputs and outputs, including an effects loop and direct out, ensures compatibility with various external devices and recording equipment.

The DT25's construction is robust, featuring a durable cabinet housing a custom 12-inch Celestion speaker, designed to deliver rich and articulate sound. Its compact size and lightweight build make it an ideal choice for gigging musicians who require a reliable, high-quality amplifier that can adapt to a diverse range of musical styles and settings.
