Great pedal Manual needs work

By: on 31 January 2024
This pedal is amazing as an impulse loader. The manual doesn't actually mention how some of the features of the pedal work though. Had to figure it out by trial and error.

Pretty Pink Nux Pulse IR

By: on 16 March 2023
Order shipped as expected. So far the product has performed very well. Will need more time to experiment with all my other pedals, amps and PC audio in. The headphone out is a practical feature very useful.
