Grobert Effects The One Preamp

The One Preamp is an analog preamp straight out of the legendary Boss™ CE-1 from 1976. It brings the signal into a warm and organic saturation. It is perfect for coloring your clean tone. It works brilliantly as a booster, and even a fuzz. Go back to your roots and go back in time almost 50 years. Find out why the CE-1 has become a legend.

LEVEL knob - The level knob works identically to the original. It set’s the volume before the preamp circuit. The louder you set it, the more saturation you get.

HIGH / LOW toggle switch - It also works identically to the original. The preamp has two modes. LOW is recommended for guitar signal. It’s less saturated, but brighter. HIGH gives you fuzz-like sound with significant high end roll off.

PEAK LED - This little, crazy white diode lights up every time your signal goes clipping.
