Presumably, the HT-Dual is so named because it has two footswitchable channels rather than one, like the rest of the HT series, making it somewhat more versatile. In reality, it\u2019s effectively a 3-channel preamp, since channel 1 offers an additional clean\/crunch option. This option is not footswitchable, so if you\u2019re going to use the HT-Dual on your pedalboard, you\u2019ll have to settle for two out of three (but that ain\u2019t bad). You can set it to \u201cclean\u201d and use channel 1 as a boost for more volume or to push a tube amp into overdrive, or you can set it to \u201ccrunch\u201d for a lower gain distortion flavor than channel 2.<\/span>

As with all of the pedals in the HT series, Dual\u2019s twin valve preamp design comes from Blackstar\u2019s idea is that using two cascaded ECC83 (12AX7) triode stages for gain instead of one, and running the tubes at appropriate amp voltages (300V) instead of \u2018starving\u2019 them, will give the preamp pedal the same touch sensitivity and playing dynamics that you get when you plug straight into an all tube amp. I have to say that it doesn\u2019t. I don\u2019t mean that it\u2019s not good, just that it\u2019s not the same. The hybrid amps I\u2019ve played smoke the solid-state modeling gear when it comes to achieving real tube amp feeling, but pedals still seem a bit further behind. So, while I haven\u2019t played them all, I generally suspect such claims of being slightly exaggerated.<\/span>

Tone-wise it\u2019s not much of a shortfall. Both of the HT-Dual\u2019s overdrive channels have really great grind, and rich, \u201ctubey\u201d harmonic distortion. They don\u2019t have exactly the same glassy-smooth compression, and they don\u2019t bark the same way a tube amp does. Even though it sounds very close \u2013 and this makes the HT-Dual a real contender in my mind \u2013 it doesn\u2019t feel exactly the same, and that affects the way I play. I know that other manufacturers of similar devices have made similar claims about different designs, and while I\u2019m sure that somewhere right now a fierce controversy rages over which method best brings real tube texture to life, I have to believe a discussion of something as subjective as tone should always recognize that different players want different things. And what the HT-Dual lacks in dynamic sensitivity, it seems to make up for in the tonal quality of its distortion and the precision of its tone shaping.<\/span><\/p>\n

The technology behind a tube-powered distortion\/overdrive\/preamp pedal is not new, but ideas about how to optimize it for guitar-playing tone hounds have begun to take some unexpected twists and turns. The HT series of “pure valve distortion” pedals from the UK’s Blackstar Amplification offers a number of new twists on the basic idea. Among them are a dual valve, true high voltage circuit, a unique tone shaping feature, and an additional, speaker emulated output. <\/p>\n

In reality, it’s effectively a 3-channel preamp, since channel 1 offers an additional clean\/crunch option. This option is not footswitchable, so if you’re going to use the HT-Dual on your pedalboard, you’ll have to settle for two out of three (but that ain’t bad). You can set it to “clean” and use channel 1 as a boost for more volume or to push a tube amp into overdrive, or you can set it to “crunch” for a lower gain distortion flavor than channel 2.<\/p>\n

As with all of the pedals in the HT series, Dual’s twin valve preamp design comes from Blackstar’s idea is that using two cascaded ECC83 (12AX7) triode stages for gain instead of one, and running the tubes at appropriate amp voltages (300V) instead of ‘starving’ them, will give the preamp pedal the same touch sensitivity and playing dynamics that you get when you plug straight into an all tube amp. I have to say that it doesn’t. I don’t mean that it’s not good, just that it’s not the same.

Tone-wise it’s not much of a shortfall. Both of the HT-Dual’s overdrive channels have really great grind, and rich, “tubey” harmonic distortion. They don’t have exactly the same glassy-smooth compression, and they don’t bark the same way a tube amp does. Even though it sounds very close – and this makes the HT-Dual a real contender in my mind – it doesn’t feel exactly the same, and that affects the way I play.
