The sound creators at NEXI are committed to providing a unique vintage tone without compromise. The Phaser PSR-01-UD pedal is the perfect analog pedal to produce those soft sweeping sounds without sacrificing on your guitars tone. Whether it is a reggae jam, funk riff or country ballads, the PSR-01-UD will have you head bobbing. Yeah baby!
The soft swooping swirls of this analog pedal will have players around the world reminiscing of the sound generated by vintage rotating speakers. The pedal simple yet extremely rugged design with its single phase switch stops you from spending hours dialing in tone. No versatility is sacrificed though as you will be able to play classic reggae, funk and country on this great pedal.
The creators at NEXI are all guitarists, with most having been on multiple tours and have even been awarded the Red Dot and iF Design Awards for their excellent product design. No one understands your needs better. The electronic board, together with the aluminium body is designed to be completely splash-proof; so you can keep playing even when the weather gets all “eerie”.
All NEXI pedals are True Bypass, are hybrid designed, and all are tailor-made to plug ‘n play meaning you can get those classic reggae tones without any fuss. This means the PSR-01-UD can be used standalone with a 9V battery, external power supply, or simply click it in NEXI’s revolutionary - The Solution - pedal board so no more cables to mess with your good vibrations, maan.
