All user reviews for the Rocktron GDP ProRax

Analog preamp distortion very solid half rack format.
Front, one can find several settings including the bass, mids that can be refined with a parametric equalizer that goes from 0.5 to 4 kHz, a gain setting accompanied by a noise gate, treble A general volume and on / off button.
At the rear, there is a jack for a footswitch that is not included and I've never used an entrance, an output jack and 2 taken in power (for AC adapter) and power out .

UTILIZATION

The settings can be intuitively without manual. The parametric equalizer mediums is very interesting because it provides additional shades to customize your sound. The breath that could appear with a significant gain can be very effectively mate adjusting the Threshold setting.

SOUND QUALITY

Simply used a Red Box direct output mixer with a guitar pickup with a Seymour Duncan Invader SH8, this preamp can provide more than one in a register saturation type Hard Rock.

OVERALL OPINION

I used it for ten years to my distorted sound but I have not had the opportunity to compare with other preamps. I use it more now because I went to the Tonelab that offers more versatility in terms of settings and sound. But I'm not ready to part with because I think that I might be still need its sound. It really is a serious little preamp that provides rhythmic as solo and has more than 20 years.
