Whiteboard

Project overview

Inspired by Jext Telez White Pedal. Designed to bring back those legendary overdrive and fuzz sounds of the late 60s commonly associated with George Harrison’s Vox amplifier.

Introduction

Let’s gather around the Whiteboard and write some tunes!

The Whiteboard was designed to bring back those legendary overdrive and fuzz sounds of the late 60s. It is based on the Vox Conqueror amp topology that was the secret weapon of bands like The Beatles and Rolling Stones when they were recording their biggest hits. When the market is filled with all sorts of pedals that you might not be sure about, you know you can at least trust the sound that sold millions of albums worldwide and made probably the same amount of girls faint.

The pedal allows you to dial in the perfect sound with minimum effort. There are only 4 knobs (VOLUME, GAIN, BASS and TREBLE) and 1 switch (VOICE) between you and the tone you’re after. The VOLUME potentiometer gives you the control over how loud the pedal is – from 0 signal, through ‘unity gain’, to pushing the amp to its limits – it’s all up to you. With the GAIN control, you can roll between a slight, sweet overdrive and crazy, wild fuzz that will make you check if your speaker is all in one piece. The EQ section is divided into BASS and TREBLE potentiometers, so you can precisely tune your tone to your liking. Just to make things more interesting, the pedal also offers a VOICE switch. With this control, you can select 1 of 3 mid-range frequencies that you want to boost, giving your tone a unique flavor.

With all that said, we already feel like we’re back in the USSR (sonically, that is). Join us there!
