Yes, the BOOST on Compadre will operate completely independently of the COMP.  This allows you to engage the BOOST side if the COMP side is bypassed.

Also, the bypass state of each side is saved per preset if you use Compadre with an external MiniSwitch to recall a favorite preset, a MultiSwitc Plus to recall 3 presets, or when using MIDI to recall up to 300 presets.

The DRY knob on Compadre is used to blend in uncompressed (dry) signal from the input along with the compressed signal when the COMP is engaged.  This allows you to preserve the attack dynamics of your playing while still enjoying the sustain provided by the compressor.  The level of the compressed signal remains consistent throughout the range of the DRY knob.

You can connect a TRS expression pedal to Compadre’s VOLUME jack to control the output volume of the pedal.  We recommend using an expression pedal with a minimum of 25k Ohm potentiometer.

  • NOTE: When Compadre is set to Buffered or Auto Bypass modes, the expression pedal will still function as a volume pedal even when both the BOOST and COMP are bypassed.

Yes!  Compadre has a full frequency response that does not filter out any of the low end.  This allows you to use Compadre with bass or any other instruments that output low frequency audio signals.

MIDI Connections to Compadre

To begin using Compadre with an external MIDI device, connect the MIDI out jack from a pedal, controller, or computer interface to the FAV/MIDI jack on Compadre. The following devices can be used to send MIDI messages to Compadre:

  • Strymon MIDI EXP cable (link)
  • Strymon Conduit MIDI Hub (link)
  • Compatible 5-pin MIDI to 1⁄4” MIDI Interface:
    • Disaster Area Designs – DPC Gen 3 Series, DMC Gen 3 Series, MIDIBox
    • Empress Effects – MIDIbox2

Configuring Compadre to Use MIDI

Set FAV/MIDI jack to MIDI Mode

Once you have connected Compadre to a MIDI source, you must set the FAV/MIDI jack to MIDI mode.

  • Press and hold the COMP footswitch while connecting the pedal to power.
  • When the LEDs stop blinking, release the footswitch and turn the BOOST knob clockwise until the BOOST LED turns BLUE.
  • Press either footswitch to store the FAV/MIDI jack assignment.

Set MIDI Channel

Next, you will need to select a MIDI channel to communicate with Compadre.  Compadre is set to MIDI channel 1 by default.

  • Press and hold down the BOOST footswitch while connecting the pedal to power.
  • When the LEDs stop blinking, release the footswitch and turn the BOOST knob to set the MIDI channel.  The BOOST LED will change color as the MIDI Channel is changed:
    • GREENMIDI Channel 1
    • AMBERMIDI Channel 2
    • REDMIDI Channel 3
    • BLUEMIDI Channels 4-16
      • This setting requires a 1/4″ MIDI connection to set.  Once the LED turns BLUE, it will blink until the pedal receives a MIDI Program Change message.  Once a MIDI PC message is received, the pedal will be set to the MIDI channel that the message was sent through and the LED will stop blinking.
      • ex. Send a MIDI Program Change message on MIDI Channel 5 to set Compadre to MIDI Channel 5.
  • Press the COMP or BOOST footswitches to store the MIDI channel assignment and begin using Compadre.
    • If selecting MIDI Channel 4-16, Compadre will automatically save the setting and boot up once a MIDI Program Change message is received.

Set MIDI Output Mode

The MIDI Output mode must be set to determine what kind of MIDI data is sent out by Compadre.  ***NOTEIf you are only sending MIDI data to Compadre or if you are using the Strymon MIDI EXP cable, the MIDI Output mode must be set to OFF.***

  • Press and hold down the BOOST footswitch while connecting the pedal to power.
  • When the LEDs stop blinking, release the footswitch and turn the COMPRESSION knob to select what kind of MIDI data is sent from Compadre to other MIDI devices.  The COMP LED will show the status:
    • GREEN – ON – Using Compadre’s knobs and switches generates MIDI messages that are sent out of Compadre.
    • AMBERTHROUGH – Incoming MIDI messages are sent out of Compadre without any additional MIDI messages generated by Compadre.
    • REDOFF (default) – No MIDI messages are sent out of Compadre.

Saving and Recalling Presets on Compadre with MIDI

Saving Presets via MIDI

***NOTE: Saved Favorite or MIDI presets on Compadre will store the settings of all the knobs and toggle switches on the pedal as well as the individual bypass states of the BOOST and COMP sides of the pedal.***

With the FAV/MIDI jack set to MIDI mode, the currently loaded settings can be saved to any of Compadre’s 300 preset locations at any time.

  • To initiate the SAVE process, press and hold the BOOST footswitch.  The BOOST LED will start blinking BLUE.
  • Send a MIDI Program Change message from your connected MIDI device to Compare.  The LED will stop flashing and C0mpadre will save the settings to the preset location that corresponds with the MIDI Program Change message it received.
    • To save a preset to the currently loaded preset location, simply press the BOOST footswitch once again while the LED is flashing.

Recalling  Presets

  • To recall presets on Compadre, send the pedal a MIDI Program Change message on the same MIDI channel the pedal is set to that corresponds to the desired preset you would like to recall.

Compadre contains 300 preset locations, numbered sequentially from 0-299. Because MIDI Program Change messages have a maximum number of 128 (0-127) the presets are grouped into three MIDI patch banks:

  • MIDI BANK 0 = PRESETS 0-127
  • MIDI BANK 1 = PRESETS 128-255
  • MIDI BANK 2 = PRESETS 256-299

Compadre always powers up in MIDI Patch Bank 0, so if you plan to stay within the first 127 presets, simply send a standard MIDI Program Change message to load a preset.

If you will be using MIDI Banks 1 and/or 2, it is advisable to send a standard MIDI Bank Change message (MIDI CC# 0 with a value equal to the MIDI Bank#) before each MIDI Program Change.

Selecting bank 0, patch 127 will put Compadre into Manual mode. In this mode, the pedal will be set to the current knob and switch settings.  No preset data can be stored at this preset location.

You can perform a factory reset to wipe all custom settings and restore all factory presets and power up modes.

To perform a factory reset:

  • Press and hold the COMP footswitch while connecting power to the pedal.
  • Once both LEDs flash, release the footswitch.
  • Sweep the DRY knob from 0% to 100% twice to RESET; status on both LEDs.
    • Turn 1 – AMBER
    • Turn 2 – RED
    • Turn 3 – AMBER
    • Turn 4 – Both LEDs blink RED, pedal resets, and power cycles
  • After the pedal power cycles during the reset, it is ready to use again.

There are 2 compression types available on Compadre:

  • studioProvides a smooth and transparent compression typically found on vintage rack compressor devices.
  • squeeze: A hard compression type that is typical of classic guitar pedal compressors.  Best for longer sustain and really clamping down on your playing dynamics.

On Compadre, you have the option of using a clean or dirty boost via the rear BOOST TYPE switch while the BOOST EQ switch selects the frequency shape.


  • clean: Boost circuit increases the output level without introducing noticeable clipping.
  • dirty: Boost circuit increases output level while introducing soft clipping characteristics of an overdrive pedal.


  • treble: Tightens up the bottom end by boosting the mid to high frequencies.
  • mid: Fattens up your signal by pushing the midrange frequencies.
  • flat: Full range frequency response.  When used with the clean boost type, provides a clean boost without affecting the tone of the signal.

To power Compadre, we recommend a power supply that provides 9VDC (center negative) at a minimum of 150mA, center-negative polarity.

Do not subject your Strymon pedal to any voltage above 9V. Doing so will damage your pedal and void your warranty.

For further information, please see our blog post on powering your effect pedals at the following link:

Gear Guide: Using the Right Power Supply for your Strymon Pedal


All Strymon pedals sold within North America (except OB.1) include a 9VDC 660mA power supply. OB.1 includes a 9V battery.

We don’t recommend using daisy chain power supplies. Ground loops are commonly caused when using a daisy chain power cable to power multiple pedals. This creates a ground loop between every pedal in the daisy chain. Ground loops allow stray magnetic fields to introduce hum into your signal path.

If the only type of effect you use is distortion you may not have (or hear) the ill effects. But, if you have modulation and delay pedals the likelihood of ground loops wreaking havoc on your signal is high.

If you don’t plan on using the included power adapter, we recommend an isolated power supply. An isolated supply works by using a transformer (or multiple transformers) to keep every power outlet completely electrically isolated. We offer two fully-isolated, high current DC power supplies, Ojai and Zuma. Click below for more info:

Zuma and Ojai - High Current DC Pedal Power Supplies
