Silver Box Booster

Silver Box Booster

“This goes to 20…” The natural extension of the guitar volume knob.
Silver Box Booster offers up to 22 dB of clean boost, a natural overdrive respectful of all executive nuances and a highly musical EQ. Moreover all that, it keeps the instrument tone colour unaltered.
From clean and bright sounds to highly dynamic crunch tones and from robust full-spectrum sounds to tones that strongly cut through the mix, Silver Box provides an “in your face” sound full of character and presence.
The perfect multi-tool for the professional musician.

Silver Box Booster comes from the collaboration between Nemphasis and musician/session player/producer/friend Marco Tafelli.

The Silver Box pedal is now an essential part of my rig. It's as at home boosting my drive pedals into ultimate saturation as it is adding muscle to clean or compressed tones. The onboard eq is great for dialling in the sweet spot for different guitars or applications and is far more musical than other eq loaded boost pedals I've used. My search for the perfect boost pedal is finally over.

Cleary the product of witchcraft, this pedal takes your sound and simply make it better! The Silver Box Booster is so much more than simply a clean boost, giving you huge tonal options and everything from clean sparkle to mild distortion coupled with all the boost any sane person could possibly desire...

Molti usano il booster per alzare il volume, e per questo ce ne sono tanti e sono tutti uguali; ma quando invece vuoi semplicemente arricchire il suono senza snaturarlo,in questo caso non sono tutti uguali . Questo pedale dimostra la qualità e la cura nel dettagli con cui sono progettati i pedali nemphasis. Io uso il Silver Box per dare più corpo e pochi db in più al mio strumento ed utilizzandolo in catena con il “White Scream” ottengo tutti i suoni che voglio senza che quasi l’ascoltatore capisca che ho un booster.
