Strymon Riverside

The Strymon Riverside is a hybrid drive and distortion pedal from Strymon, introduced at the end of 2016 as the company's first overdrive pedal¹. Where a typical overdrive uses one clipping stage, Riverside runs a cascading multistage topology: an all-analog, discrete Class A JFET input gain stage feeding three DSP gain stages based on the asymmetric clipping characteristics of preamp vacuum tubes². The result, Strymon says, is a range running "from silky clean overdrive to colossal distortion and all points between"³.

Strymon sums up the design philosophy as "Digital or analog? We chose both," with the analog JFET front-end carrying the dynamics and feel and the DSP gain stages shaping the drive³. The pedal remains in production at a list price of $299.00⁴.

What it does: a multistage drive from overdrive to distortion

Riverside covers the whole drive spectrum in one pedal. Strymon's demo material describes "subtle overdrives, rich saturated distortions, and a full range of tones you'd find" in tube amplifiers, and Guitar World's launch coverage called it "an incredibly versatile drive pedal that is equally capable of providing sparking cleans, mild overdrives, high-gain leads, and heavy saturated distortions"³⁶. The pedal has two gain channels: a low gain channel for smooth classic overdrive and a high gain channel for modern saturated distortion⁵.

Because the gain stages cascade rather than pile onto one clipping point, Delicious Audio's product page describes the tones as "harmonically rich" and "immensely musical and natural"⁷⁵. A key part of the design is the Drive knob itself: as you turn it, Riverside makes continuous adjustments, tuning many circuit parameters at once for optimum tone rather than simply raising one gain value⁵³.

How it works: an analog JFET stage into DSP gain stages

Strymon's answer to the analog-versus-digital question for Riverside was "We chose both"⁵. The signal path breaks down like this:

1. The first gain stage is a discrete Class A JFET circuit, all analog and ultra low noise, which Strymon says maximizes headroom while adding up to 20dB of pure analog gain⁵². Guitar World's coverage noted this stage is what makes the pedal "respond to your guitar with uncompromised dynamics and feel"³.
2. The following three gain stages are DSP stages based on the asymmetric clipping characteristics of preamp vacuum tubes².
3. A three-band EQ (Bass, Middle, Treble) and a Presence switch shape the output.

Strymon sound designer and DSP engineer Pete Celi presented the design in the company's own technical analysis and demo videos⁸. MusicRadar's launch coverage characterized the hybrid approach as promising an "infinite sweet spot" at any setting⁹.

The controls and footswitches

The two footswitches do more than their faceplate labels suggest. Holding ON at power up enters bypass mode setup; holding FAVORITE at power up configures the EXP jack for Volume or MIDI mode¹⁵¹¹. An external footswitch can also access an in-built boost of up to 6dB, as noted in Guitar.com's review¹⁶.

Power and connections

Riverside runs on a maximum of 9 volts DC, center negative, with a minimum of 250mA of current⁵. The connection is a standard 5.5mm x 2.1mm barrel, and no power supply is included⁵.

Connections are simple: a high impedance mono input for your instrument and a single mono output for your amp, other pedals or a mixing board⁵. Riverside is not stereo; Strymon excludes it from its mono input to stereo output setups¹⁷. The enclosure is a strong and lightweight anodized gold aluminum chassis, 4.5" deep x 4" wide x 2.4" tall, designed and built in the USA⁵. Strymon covers it with a two year limited warranty that is non-transferable, with no registration; keep your original sales receipt from an authorized dealer¹⁸.

MIDI, presets and expression

The EXP jack is the heart of Riverside's deeper features. It can operate three ways⁵¹²¹¹:

• Expression mode: continuous expression pedal control over any or all of the knobs, in any direction, with the factory assignment set to control Drive⁵¹⁹.
• Volume mode: the expression pedal controls overall output volume with a logarithmic audio taper, and it still works when Riverside is bypassed if the pedal is set to buffered bypass¹¹.
• MIDI mode: with a 1/4" MIDI connection such as the Strymon MIDI EXP cable, Riverside offers remote parameter control, control of all knobs and switches via MIDI, and access to 300 preset locations⁵¹².

MIDI control requires firmware version 1.22 or later¹². The 300 presets are organized as MIDI Bank 0 (presets 0 to 127), Bank 1 (presets 128 to 255) and Bank 2 (presets 256 to 299), and Riverside always powers up in MIDI Patch Bank 0¹². Bank 0, patch 0 recalls the on-board Favorite preset, while bank 0, patch 127 puts the pedal into Manual mode, set to its current knob and switch settings¹². To save a preset, press and hold the FAVORITE footswitch to enter SAVE mode, then send a MIDI Program Change message to choose the location¹².

MIDI channel and output mode are set at power up: hold ON while connecting power, turn the DRIVE knob to set the channel (the FAVORITE LED color indicates it: green for channel 1, amber for 2, red for 3, blue for 4 to 16) and the MIDDLE knob to select the output mode: OFF (default), THROUGH, or ON, where Riverside's own knob movements generate MIDI output¹²²⁰. When MIDI Out or Through is enabled, MIDI data leaves the pedal from the ring of the TRS connection²¹. Confirmed compatible senders include the Strymon MIDI EXP cable, the Strymon Conduit MIDI Hub, Disaster Area Designs DPC and DMC Gen 3 series, MIDIBox and the Empress Effects MIDIbox2¹².

Firmware updates and factory reset

Firmware updates run through the Strymon Update software over a micro-USB cable¹². The port is inside the chassis, so you remove the bottom plate first, and the pedal must be powered from its own supply while connected to the computer²². To check your firmware version, hold the ON footswitch until the LEDs blink, release, then turn the TREBLE knob: on version 1.0 firmware the ON LED color does not change¹².

A factory reset returns every setting to its shipped state: Noise Reduction OFF, BOOST Amount at 50%, True Bypass, the EXP jack in Volume Pedal mode and the expression assignment on Drive¹⁹. Hold ON while plugging in power, release, then turn the BASS knob from 0 to 100 percent twice; the FAVORITE LED blinks red while the reset happens and stops when it is complete²³.

History and versions

Riverside was teased in October 2016 with a blurry image on the Strymon website before its full announcement²⁴, and That Pedal Show dates its introduction to the end of 2016¹. Pedal of the Day called it Strymon's "first foray into the world of overdrive"²⁵, notable because the company had built its name on time-based effects; Guitar.com observed that Riverside was "a little different to their previous work"²⁶. It was sold directly through the Strymon online store and through select authorized dealers³, and it still is.

There is only one version of Riverside. It was followed in the drive category by the Strymon Sunset Dual Overdrive, and much later by the all-analog Series A line beginning with the Strymon Fairfax in December 2025 and the Strymon La Brea Tape Saturation Drive in September 2026, pedals that take the opposite approach: pure analog circuits where Riverside is a hybrid.

What reviewers said

Guitar Pedal X's Stefan Karlsson, reviewing Riverside in a Blues Driver lineage piece, found it "has just the right core tonality, calibration and range to deliver fantastic Blues Driver style tones," calling it a long-term favorite and very easy to dial in¹⁰.

JHS Pedals' Josh, discussing underrated overdrives, said of the circuit: "it has a true class, a FET stage that goes into DSP gain stages," adding "I honestly love this multi-stage Riverside drive"²⁷. Guitar World's Alex Lynham, reviewing the Crazy Tube Circuits Triptychon in 2026, pointed lower-gain players toward Riverside: "For lower-gain tones, there's the Strymon Riverside"²⁸. Early video coverage included a demo by Rob Chapman's The Andertones show, and Delicious Audio reported that "the responses so far seem as positive as expected"²⁹.
