Retrospec Juice Box


The Juice Box’s audio circuitry is class “A” from start to finish.


That and the absence of a transformer explain the conspicuously low distortion spec. It also employs a low impedance high voltage power supply, and a D.C. filament circuit just to keep things nice and quiet.

Retrospec then took one significant step further and included enough gain and headroom to be able to drive a 10k input at professional line level. Now you can go from instrument to console channel line in or direct to tape machine in one sweet clean step! Don’t take our word for it; ask the artists, engineers, producers and studio owners who have put it to the test!

"Tested with my Fender Strat Plus, the DI'd guitar tone was clean, articulate and responsive, with a lot more tonal change between the different pickup switch settings than you might expect. The sound had that even, 'ringing' characteristic that you get from the best tube amps, but without any of the noise or distortion. Of course, this is only of any use when you're recording clean sounds, but the sort of clean sounds that you get make you want to keep playing, even when no additional EQ is used. Having painted such a rosy picture, I must admit that I obtained similarly transparent results from one of my better solid-state guitar DI units, though, to be fair, the Juice Box is slightly warmer sounding in a direct shoot-out. Even so, I feel that the main benefits come from its high input impedance and wide bandwidth rather than from any mystical tube-distortion mechanism. Whatever the reason, this is a very nice-sounding DI box that's close to perfect for use with undistorted electric guitar and bass" Paul White Sound On Sound
