Line 6 DT25-112

The Line 6 DT25-112 is an interesting modeling amplifier that combines tube components, digital modeling and analog circuit switching. Co-designer Reinhold Bogner added a Class A to Class A/B and triode to pentode switching, which works in conjunction with the amp's 12AX7 preamp tube and dual EL84 output tubes, for more control over tube tone nuances. Instead of going the easy multi-amp model and digital control route, the DT25-112 is stripped down with just four main voicings that can be achieved via a switch and some knob tweaking. The four main voicings are described as American clean, English chime, English crunch, and modern high-gain. But it doesn't end there because you can get more voicings by tweaking the parameters to your liking. Finally, this amp's main draw is its compatibility with Line 6' line of POD HD guitar processors, it automatically configures its analog components to match the modeled amps on the processor.

Most DT25-112 owners are also Line 6 POD HD owners, and since they get the most out of the amp, they have mostly good things to say. But it's not just for Line 6 fans because other were just as impressed with the amp's realism and overall sound quality. This review conclusion from Sound on Sound reflects much of what the market feels about the amp: "I think the DT25 manages to pull off the trick of looking, sounding and feeling authentic, while combining the flexibility of modelling and switchable power-amp topographies". There were a few users who found the learning curve to be a bit too much, compared to the usual modeling amplifier, but they were satisfied when they finally got the sounds they wanted.

If you are a Line 6 POD HD owner, then the Line 6 DT25-112 is a no-brainer. It will also be a good addition to anyone who wants a versatile tube-driven modeling amplifier.
