The Line 6 DT25 112 1x12 25W Tube Guitar Combo Amp is four boutique tube amps in one, American clean, British crunch, class A chime, and modern high-gain.
Featuring reconfigurable analog components, the Line 6 DT25 also includes HD modeling. This allows you to select your operating class to either Class AB/25 Watts/Fixed Bias or Class A/10 Watts/Cathode Biased. You can choose between two power tube modes: pentode or triode. The four amp voicings offer combinations of negative feedback loop topology, and HD preamp and tone stack modeling. You can save different combinations of Voicing, Operating Class, and Power Tube modes to each of the two channels. Both channels have Drive, Bass, Mid, Treble, Presence, Reverb, and Channel Volume controls for dialing in your tone.
There is also a Channel switch, Voicing switch, Pentode/Triode switch, Class A/Class AB switch, Master Volume control, Power switch, and a Standby switch. Everything is easily readable, using the backlit front panel. Each channel has its own Modeled Spring Reverb. The DT25 includes a MIDI I/O, and a series effects loop. There is also a cabinet-simulated direct output and a Low Volume Mode that provides cranked up tube tone at low volume. One 12AX7 tube in the preamp section and two EL84 tubes in the power section power the 12-inch Custom Celestion G12H90 speaker.
