The Blackstar HT-Reverb can take guitarist from a room to an arena via hall, plate, spring, gate and reverse reverb effects. Valve compression and harmonics are added using the Dwell control, and guitarists can switch the reverb time from short to long while playing.

The Blackstar HT-Delay can take guitarists from vintage and multihead tape head delays, through classic analogue and linear full bandwidth effects and two loop modes as well. Each of the eight delay effects have been designed by technical reference to emulate vintage equipment and then extensively honed "by ear" to provide sounds that are both natural and inspirational to the player. 

From gentle tremolo to roaring jet engine flange, the Blackstar HT-Modulation brings all the musicality of the classic vintage effects pedals. Each of the eight reverb effects have been designed by technical reference to emulate vintage equipment and then extensively honed "by ear" to provide sounds that are both natural and inspirational to the player. 

By allowing infinite adjustment over the characteristics of the Blackstar HT-Dist pedal's tone control network, the patent-applied-for ISF circuit allows guitarists to effectively design their own tone and find "the sound in your head." Add to this the dynamics of the high voltage tube design and a no compromise speaker emulated output and this pedal is a classic amongst modern distortions.
