Read the brief

The MXR Dyna Comp is a guitar compressor pedal introduced in the 1970s. It has two controls: Sensitivity and Output. It produces a non-tone-neutral, colour-rich compression effect. It became a Nashville standard. It smooths out volume differences between notes, especially in chicken picking. It was one of the six original pedals in the MXR Series 2000 line.

  1. 0:54
    What it is

    It is an MXR-built guitar effect, not a studio rack unit or bass-only tool.

  2. 1:57
    How it works

    Two knobs only: Sensitivity sets compression threshold; Output sets final level.

  3. 3:02
    What it does best

    It excels at smoothing chicken-picked runs and became a Nashville standard for that reason.

  4. 4:18
    What it gives up

    Its tone colouration is inseparable from its function—and it’s been copied endlessly because of it.

  5. 5:18
    Where it sits in MXR history

    It launched as one of six original Series 2000 pedals—with FET switching, dual LEDs, and a metal chassis.

The written brief1 min read

What it is and what it was built for

It is a guitar effects unit built to compress dynamic range. It was designed for electric guitar, though bass players use it too.

How it works, in terms a player would use

It compresses dynamic range using two knobs: Sensitivity sets how much signal triggers compression; Output sets the final volume. It does not offer attack, release, ratio or makeup gain controls.

What it does better than anything else

It smooths volume differences between fast, unevenly picked notes better than any pedal with only two knobs—and it does so with a distinctive squish and sustain that cuts through a Nashville mix.

What it does badly

It cannot deliver transparent, studio-grade compression. It does not let players shape transients or dial in subtle dynamics control. Its tone colouration is baked in and non-bypassable.

What people made with it

Players used it to lock in chicken-picked country licks, extend note decay, and create a consistent, punchy front-end tone—especially in Nashville studios and sessions.

Who should use it, and who should not

Guitarists who want immediate, characterful compression with zero setup should use it. Players needing surgical dynamics control or neutral tone should not.

Is it worth your time

Yes—if you want a fixed, colour-rich compression that glues chicken-picked lines and sustains notes without transparency or fine control.

MXR Micro AmpMXR · 1978The MXR Micro Amp (M133) is an op-amp boost pedal released in 1978. It has a single volume control and offers 26 dB of boost, meant to add volume or distortion, depending on where it sits in the signal chain, without colouring the tone. It has become perhaps the most commonly used boost pedal on the market.

MXR Flanger/DoublerMXRThe MXR M126 Flanger/Doubler is a two-space analog rack unit with front-panel 1/4" TRS I/O. It gives players manual, sweep width, sweep speed, mix, and regen knobs plus mode and bypass/invert buttons. It delivers a thick flanging sound and fulfils its synthetic doubling function as advertised. It has no stereo I/O, no expression input, no tap tempo, and no presets. No verified recordings or users are cited. Studio engineers needing fixed, tactile analog flanging or doubling should consider it. Live performers, modular users, and those requiring stereo or foot control should not.

MXR FlangerMXRThe MXR Flanger is a guitar flanger pedal. No technical specifications are available. It belongs in the category of flangers for guitar. That is all the material confirms.

Ibanez Tube Screamer TS808IbanezThe Ibanez TS808 Tube Screamer Reissue is an analog overdrive pedal in the Tube Screamer series. It has three knobs: tone, level, and overdrive. It uses the JRC4558 chip. It runs on a 9-volt battery or AC adapter. Its metal housing is 4.9" x 2.8" x 2" and weighs just over a pound. It delivers warm, smooth, mid-heavy overdrive suited for solos and blues-rock—not high-gain riffing. It is very strongly built.
