Free The Tone OVERDRIVELAND / ODL-1-CS Custom Shop Overdrive Pedal

OVERDRIVELAND was born to be as lustrous and distinctive as the elusive DUMBLE amps that are now hard to come by, allowing players to express their unique personalities.

The unit features a solid die-cast case with laser engraving. Each unit has a unique, rugged surface finish for you to appreciate.

Background of Development:

FREE THE TONE's founder and designer, Yuki Hayashi, amassed over 20 years of experience in maintaining and repairing DUMBLE amplifiers and was a proud owner of multiple DUMBLE amps himself. DUMBLE amplifiers are known for their distinctive harmonics, which can make even clean sounds seem slightly distorted. Furthermore, the drive sound of a DUMBLE amp responds to a guitarist's playing as if the amplifier itself possesses intention. It was this desire to capture this unique feel and translate it into a pedal-sized overdrive pedal that sparked the development process.

How to Use and Features:

The Signal Flow for Normal Channel and Drive Channel OVERDRIVELAND consists of two main sections. The first is the Normal Channel circuit, through which the signal passes when the Normal Channel is selected. This circuit includes the Tone circuit (including the EQ ON/GLASS switch) and Gain characteristics adjustment with the ROCK/JAZZ switch.

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.

The Normal Channel features the "EQ ON/GLASS" and "ROCK/JAZZ" switches to help set the foundation for your sound.

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.

When you select the Drive Channel in OVERDRIVELAND, the Drive circuit is added in front of the Normal Channel circuit. In other words, from the input side, the signal flows in the following order: Drive circuit, Normal Channel circuit, and then the output circuit. The Drive circuit is equipped with a "HI-CUT" filter circuit, making it easy to adjust the high-frequency characteristics. Additionally, the "PUSH" control adjusts the signal level sent from the Drive circuit to the Normal Channel, allowing you to control the perceived volume level. You can also adjust the volume when the Drive Channel is selected using the "DRV LEVEL" knob.


• The unit features a solid die-cast case with laser engraving. Each unit has a unique, rugged surface finish for you to appreciate.
• For the custom shop version, custom modules are used with different components than the standard version in order to respond more sensitively to input signals.
• Equipped with a ROCK/JAZZ switch for toggling gain and frequency characteristics (Normal Channel).
• Features a "GLASS" switch to bypass the TONE circuit and achieve a glass-like sound (Normal Channel).
• Independent output level adjustments for Normal Channel and Drive Channel.
• Incorporates the HTS (Holistic Tonal Solution) circuit, which differs from traditional buffer circuits. It maximizes the sound characteristics of the guitar while performing impedance conversion, achieving a balance between "sound" and "low noise." The HTS circuit prevents sound quality degradation even when the effect is turned off. Additionally, the output signal is in phase with the input signal, eliminating concerns about phase inversion.
