The TC Electronic ND-1 Nova Delay pedal raises the bar for guitar effect pedals and redefines what it means to be “state-of-the-art”.

The TC Electronic ND-1 Nova Delay offers uncompromised studio quality digital effects in a compact floor-based design. The ND-1 Nova Delay is a stereo delay pedal with two settings: Manual, which represents the current position of the knobs and Preset, which is a stored sound that can be recalled at any time. These may be selected from control buttons or the manual/preset footswitch.

The ND-1 Nova Delay pedal features 6 different delay types: Delay line, dynamic, reverse, ping-pong, pan and slap-back. Each of these types can be combined with a delay style ranging from vintage tape to modern digital delay. This unique feature allows you to mix and match your delay type and style to create unique sounds.

Both single delay and dual delay lines can be applied to any type and style using the tap tempo switch or delay time knob to determine the speed of the delay. Three different types of modulation (light, medium and heavy) can be applied to any of the delay types – a feature originating from the legendary TC 2290 Dynamic Digital Delay processor.

The all-new Audio Tapping technology enables you to set the tempo of the delay by playing a rhythm into the pedal while holding down the tap tempo switch. You can now set the tempo of the delay using your most important asset: Your playing. Other great Nova Delay features include the ability to choose between ms (millisecond) and bpm (beats per minute) readout, decide if you want spillover on none, one or both settings and turn global tempo – where tap tempo determines the delay time on both settings – on and off.
