The HT-MODULATION pedal operates on a 300V DC anode supply voltage (High Tension voltage). This is the same used in traditional valve amplifier design and means the circuit has all the compression and distortion characteristics associated with a true valve amp design and therefore 'cleans up' in the same way when you back off the volume on your guitar.
From gentle tremolo to roaring jet engine flange, the HT-MODULATION brings you all the musicality of classic vintage effects pedals. The effects include Flanger, Phaser 1, Phaser 2, Vintage Chorus 1, Vintage Chorus 2, Multi Chorus, Tremelo and Rotary. These combined with the Speed, Feedback and Saturation controls you really can get the modulation effect your after.
By adjusting the drive to the high voltage valve circuit in the effect side chain, Saturation affects the amount of valve compression and harmonics in the effect.
The HT-MODULATION features manual and short/long modes for maximum playing flexibility. The manual mode is a time control that sets the reverb decay length. The footswitch toggles between preset slow and fast speeds for live flexibility. The LED flashes in time with the speed.
Many hours of research showed us that only soft switching and a buffered bypass signal will give absolutely silent switching in high gain applications.
All Blackstar pedals are subjected to extensive laboratory and road testing to ensure that they are truly uncompromising in terms of reliability, quality and above all tone. You can throw them in the van and take them on the road and not have to worry.
The HT-BOOST's buffered bypass signal means there are no problems presented by driving long cable runs or chains of other effects.
