FREE THE TONE Overdriveland Standard ODL-1 Free The Tone

I experimented with various methods, whether adding a different circuit before or after the normal channel circuit or inserting a circuit in between. I also took inspiration from the sound and equipment connections used by Brian May and Gary Moore.

Ultimately, I added a drive circuit that uses a dedicated module before the normal channel circuit and adopted a method to adjust how much signal is sent to the input stage of the normal channel. By adjusting this signal level, I can control the perceived volume level. This is the role of the “PUSH” knob.
To finely respond to the input level, I not only developed a dedicated drive circuit module but also designed a new power supply circuit. In order to use OVERDRIVELAND with a standard DC9V power source, I incorporated a power supply boost circuit that can increase the supply voltage to the analog circuit from DC9V to a maximum of DC19V. By adjusting the voltage of this boost power supply circuit, the dynamic range of OVERDERIVELAND and the clipping point of the signal can be altered. Lowering the voltage reduces the level of the clipping point, resulting in long sustain. Conversely, increasing the voltage raises the level before reaching the clipping point, giving a sound that really cuts through. This feature is highly effective and can produce different sounds as if there were entirely separate overdrive pedals available.

By adjusting the harmonic components of the input guitar signal, OVERDRIVELAND offers a unique sound that balances well across all strings, from the 1st to the 6th (or 7th) string. It becomes an instrument that can expand the possibilities of expression.
Please feel free to explore these possibilities with OVERDRIVELAND.

The second section is the Drive circuit. When the Drive Channel is selected, the signal passes through this Drive circuit before flowing into the Normal Channel circuit.

To begin crafting the foundational sound of OVERDRIVELAND, start with the Normal Channel, which provides a clean to crunch sound. Begin by setting all the knobs to their center positions and play some notes. The harmonic components will change with the strength of your picking, altering the tone. The Normal Channel offers a rich tone that can bring out various phrases from the player.

Adjust the “GAIN” knob to achieve your preferred level of distortion, and adjust the volume using the “NOR LEVEL” knob.

The “EQ ON/GLASS” switch controls the equalization function of the Normal Channel. When set to “EQ ON,” the “TONE” circuit is activated, allowing you to shape your tone. Selecting “GLASS” bypasses the “TONE” circuit, giving you a glassy tone reminiscent of turning on the Bright switch on a Blackface Fender Vibroverb.

The “ROCK/JAZZ” switch adjusts the frequency response and gain settings of the Normal Channel. The “ROCK” side is designed for shaping your sound with increased gain, while slightly reducing the gain in the low-frequency range to prevent excessive low-end volume that can cause the amp’s input stage to distort. The “JAZZ” side, on the other hand, lowers the overall gain and is designed to bring out the richness in the low-frequency range.
