Analogue distortion effect pedal from LT Pedals series that features Blackstar’s patented ISF (Infinite Shape Feature) circuit, providing an infinite adjustment over the characteristics of the tone control and taking the sound from the USA to the UK and anywhere in between. The Gain control adjusts the amount of overdrive or distortion that the pedal will deliver. At low settings, counter clockwise (CCW), the pedal will deliver a clean boost, which in conjunction with the Level control can be used to overdrive an already distorting valve amplifier. As the Gain control is increased clockwise (CW) the sound will become more overdriven moving through crunch tones until, at its maximum position, a full distorted lead tone is arrived at. The Tone control allows exact adjustment of the treble frequencies within the sound. At low settings, counter clockwise (CCW), the sound will be warm and darker in character. As the control is increased clockwise (CW) the sound will become brighter. At the maximum settings the tone will be aggressive and cutting. The ISF control works in conjunction with the Tone control and it allows user to choose the exact tone signature he prefers. Fully CCW is a more American characteristic with a tight bottom end and more aggressive middle, and fully CW is a British characteristic which is more ‘woody’ and less aggressive. A unique clipping circuit in the pedal has been designed and tested to behave just like the successful Blackstar HT pedals. The pedal can be powered by using a 9V battery or by using a 9V DC power input. Dimensions: 60 x 54.5 x 122 mm. Weight: 0.45 kg.
