The Line 6 DT25 Head is a bit of a departure from their usual feature packed amps.

With just four basic amp voicings, it may seem a bit streamlined, but its complexity lies in its reconfigurable tube circuit, co-designed by Reinhold Bogner, which employs a 12AX7 preamp tube and two EL84 power amp tubes.

The analog components of this amp are designed to switch between Class A to Class A/B, as well as from triode to pentode, widening its sonic horizons.

It shines best when paired with Line 6 guitar processors that connect via their L6 LINK connection. The amp automatically configures its tube and analog components to match the amp modeling settings on the processor.

The Line 6 DT25 Head gets a lot of complements from users of Line 6 guitar processors, rightly so because they get the most out of the amp and processor. It is mostly praised for its versatility, but it also wows owners with its tone, many of which comment that the amp improved their sound by a big margin. Many users also like the overall craftsmanship and classic appeal of the amp. Paul White of Sound on Sound concludes his review by saying: "Ultimately, I think the DT25 manages to pull off the trick of looking, sounding and feeling authentic, while combining the flexibility of modeling and switchable power-amp topographies."

The minority who utilize the DT25 HD as a stand-alone amp also have good things to say, but they do miss out on what the amp does best, and that is to add the nuances of an actual tube amp to Line 6 amp models found on their guitar processors. There are also a few users who report that the amp does not take analog pedals well, although they are balanced out by others who have better experience with using their pedals on the amp.

If you're a Line 6 fan, or if you own any of their guitar processors, then the Line 6 DT25 Head is a no-brainer. For those in the other camp, the amp still has a lot to offer with its Bogner designed tube circuit that can be reconfigured conveniently.
