Bass Mono Synth Bass Synthesizer



The EHX Bass Mono Synth transforms your bass into eleven great sounding synthesizers... from vintage synth emulations to thick, stacked voices to deep pulsing sounds and more.

Its intuitive layout makes it easy to use and easy to dial in good sounds quickly. DRY controls the volume of your dry bass signal at the Synth Output. SYNTH controls the volume of the Synthesizer sound at the Synth Output. Used together they let you create just the right mix. The SENS control, short for sensitivity, adjusts how your playing dynamics trigger the synthesizer and allows you to fine tune the way the pedal responds to your bass rig and playing style.

With the CTRL knob you can adjust a key parameter for each of the eleven synth types. It varies depending on the preset and provides more tweakability for customizing your sound. There’s also an EXP input which lets you control an entirely different parameter in real-time with an expression pedal!

Using the built-in Preset footswitch, a user customizable preset for each of the eleven synth sounds can be created, saved and recalled. The factory presets are also easy to restore should you wish to.

From lush, warm sounds to sharp, percussive stabs, the Bass Mono Synth puts a collection of cool bass synths at your fingertips.

EHX unveils the Bass Mono Synth which transforms a bass guitar into 11 different bass synthesizers, from vintage synth emulations, to thick, stacked voices to deep pulsing sounds and more.



The Bass Mono Synth was designed to work on bass guitar without any modifications, special pickups or MIDI implementation. Its intuitive layout makes it easy to use. The pedal’s DRY dial adjusts the dry bass volume at the Synth Output while SYNTH controls the volume of the synthesizer sound at the Synth Output. Used together they provide enhanced level mixing. The SENS control, short for sensitivity, adjusts how playing dynamics trigger the synthesizer and permits fine-tuning the pedal’s response to a player’s bass rig and playing style.

With the CTRL knob the bassist can adjust a key parameter for each of the 11 synth types. It varies depending on the preset and provides extra “tweakability.” There is also an EXP input that lets the player control an entirely different parameter in real-time with an expression pedal.

EHX Founder, Mike Matthews, stated: “From lush, warm sounds to sharp, percussive stabs, the Bass Mono Synth puts a collection of cool bass synths at your fingertips.”

The Bass Mono Synth comes equipped with an EHX 9.6DC-200mA power supply and is available now at authorized EHX dealers.

Our new EHX Strings Electro-Harmonix electric guitar strings are custom-designed to our specifications and made in the USA by a premiere string manufacturer. Each wound string is precision wrapped with round nickel-plated steel onto a high carbon, hexagon-shaped steel core. The plain strings are made from the same high carbon steel as the hex cores. The high quality steel and computer controlled winding process results in strings that intonate accurately, are better at staying in tune and vibrate evenly for maximum sustain.
