Get distinct, reactive overdrive inspired by the highly sought-after Dumble sound. Switch between the NORMAL or DRIVE circuit to choose how hard to push your amplifier, and choose between ROCK & JAZZ for distinct tonal differences which react really well to the articulation of how hard you play, letting you express yourself even with a full distortion in play.
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.
Key Features
- Versatile, Reactive Overdrive – Switch between the ROCK/JAZZ switch, and change between the NORMAL or DRIVE circuit for extra versatility.
- Rugged Chassis – The unit features a solid die-cast case with laser engraving. Each unit has a unique, rugged surface finish for you to appreciate.
- Natural Response – 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.
- ROCK or JAZZ – Equipped with a ROCK/JAZZ switch for toggling gain and frequency characteristics (Normal Channel).
- Bypass the Tone – Features a “GLASS” switch to bypass the TONE circuit and achieve a glass-like sound (Normal Channel).
“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.”
Background
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.
Channels & Controls
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.
