Project overview

Anyone called an Uber?

The Uberdrive is a unique pedal inspired by the John Hollis Omnidrive, a pedal that you won’t be able to get unless you make it yourself. Yes, it’s a DIY exclusive! The circuit contains four knobs – VOLUME, GAIN, TONE and BLEND. It also offers additional five switches to fine tune your tone – BOOST, FILTER, OCTAVE, MODE and SCOOP.

Introduction

Let’s have a look at the pots first. The VOLUME control lets you set the loudness of the pedal to the desired level. The next one is GAIN, which allows you to control how much saturation is added to the signal. The TONE potentiometer is a classic mid-range control. With BLEND, you are able to decide how much of the clean tone you want to add to the distorted sound.

Now to the switches, where all the fun begins. The BOOST you are able to engage a treble boost on the preamp. FILTER is quite the opposite – it allows you to cut some of the highs. The OCTAVE switch… you guessed it! It adds an octave effect to your notes. With MODE you are able to switch between two different clipping options, giving your current settings a different character. SCOOP is a gift from the norse gods to all the death metal fans that wish to cut the mids from their sounds and never to think about them.

Put your seatbelts on, because the Uberdrive will take you on a ride to all the places you know and the ones you’ve never been to. Tak your bassist with you too, as some of the places are just made for the low-end riders!
