Bass Chorus Deluxe

The MXR Bass Chorus Deluxe is powered by pure analog bucket-brigade technology, serving up shimmering, liquid chorus and swooshing, metallic flanger effects while preserving the punch and fundamental of your low end.

The Bass Chorus Deluxe features top-mounted Flanger and X-Over buttons with LED status indicators. In X-Over Mode, modulation in low frequencies is decreased at 100Hz—perfect for playing upper register chords, melodies and fills while keeping the low end in tune. With Bass and Treble controls you can cut or boost lows and highs and shape the tonal character of the effect. For a wide stereo sound, select the TRS (tip-ring-sleeve) Stereo Hardwire Bypass Mode via an internal switch. In this mode, you can use a TRS to TS (tip-sleeve) Y-splitter cable to send the effect signal to two different amplifiers, allowing the modulation to move from left to right.

The Bass Chorus Deluxe joins the ranks of award-winning pedals in the MXR Bass Innovations line, each designed by bass players for bass players.

"The MXR Bass Chorus keeps it tight in the low end while providing either a great chorus or flange to your bass lines." - Juan Alderete, Racer X / The Mars Volta

"I'm a long-time aficionado of chorus effects, but it's sometimes tricky getting the sound to jive just right the low-end of bass guitar. The new MXR Bass Chorus is a great solution. It not only retains the lows well, but also gives a particularly rich and unique chorus effect. Great on synth bass too. Highly recommended."- Justin Meldal-Johnsen

Bass Compressor

Take your favorite studio compressor to the stage with the MXR M87 Bass Compressor. A complete array of controls—Attack, Release, Ratio, Input, and Output—makes it easy to fine-tune your sound, from subtle peak limiting to hard squashed compression effects. Its CHT™ Constant Headroom Technology gives you plenty of headroom and clear performance. This totally transparent compressor allows your full dynamic range to shine through until your signal reaches the compression threshold, which is indicated by the ten, highly visible gain-reduction status LEDs. It’s all packed into a durable, lightweight aluminum-housing pedal that’s the size of a Phase 90.

“Finally, a five-knob compressor in a pedal. I’m a compression aficionado, and this box kills! All parameters are tweakable.” Billy Sheehan

"Historically, compressor pedals give me the heebie jeebies. So when this pretty pedal showed up sounding all natural and punchy with a cool gain-reduction meter, quelle surprise! Nice job MXR." Justin Meldal-Johnsen

Bass D.I.+

Finally, all the essentials in one tough little box. You need a serious D.I. for playing live and laying down killer tracks. You've got to have a preamp and finely tuned EQ to add punch to your tones. And you definitely can't do without some rich, custom distortion. This one-of-a-kind pedal gives you the whole deal in a bomb-proof enclosure that will survive even the most out of control gigs-and players. Built with the highest quality components, the M-80 can give you eve everything from warmth and transparency to a volcanic roar, without making you scroll through menu screens or an indecipherable manual. Engage the color switch for some sweet preset EQ, then tweak your tone with three band control. Dial in your ideal distortion with the gain knob and blend just the right amount into your clean signal, then kick it on and off at will. The adjustable noise gate pours on the sustain and cuts out hum and hiss. With XLR and parallel 1/4" outputs and a phantom power switch, you'll never have a problem delivering your choice new tones. Power: Single 9 volt battery or Dunlop ECB003 AC Adapter

Bass Envelope Filter

The Bass Envelope Filter delivers classic, analog, envelope filter sounds in an easy-to-use and compact pedal designed specifically for bass. Separate Dry and Effect controls let you dial in the perfect mix of effected and direct signals, so you can bring the funk without losing the low end. Its wide range of filter tones can be shaped with the Decay and Q controls, and a simple twist of the Sensitivity knob can tailor the pedal for your attack—as well as adjust for passive or active basses. The Bass Envelope Filter's power supply circuitry is designed to withstand over-voltage or polarity mishaps, and its true-bypass switching preserves your tone in bypass mode. It's all packaged in a durable, lightweight, Phase 90-size aluminium housing for the ultimate in portability and pedalboard space-saving dimensions.

Bass Fuzz Deluxe

Next up in the award-winning MXR Bass Innovations line is the Bass Fuzz Deluxe. We dug up a rare vintage fuzz and modified it for the modern bassist. The resulting stompbox delivers a cutting and bold fuzz tone without degrading the punch and clarity of your original signal.

With separate Dry and Wet level controls, the Bass Fuzz Deluxe sounds like you’re running two different amps. Blend to taste, from subtle hairiness to full on raging fuzz, with Fuzz and Tone controls affecting only the Wet signal. The Bass Fuzz Deluxe features true hardwire bypass.

Bass Octave Deluxe

The M288 Bass Octave Deluxe is a dual-voice octave pedal that offers analog tone, true bypass, and a variety of tonal options. MXR's 18 volt Constant Headroom Technology™ provides high headroom and superior tracking. Use the Dry knob to mix in your direct signal, and hit the Mid+ switch to add up to +14dB of internally adjustable mid frequencies (400Hz or 850Hz). Finally, mix in two separately controlled octave voices—Growl (for throaty tone) and Girth (for deep tone).

Bass Overdrive

The MXR Bass Overdrive is an original design that delivers warm, tube-like overdrive. Along with standard Volume, Tone and Drive controls, this pedal features a Clean control so you can blend a pre-set EQ clean signal with the overdrive signal, resulting in sweet burly bass overdrive.

""Punch your bass into the mix with the help of the MXR Bass Overdrive." - Juan Alderete, Racer X / The Mars Volta

Bass Preamp

The MXR Bass Preamp combines a pristine bass preamp with a studio-quality Direct Out in a Phase 90-sized box, providing clear tone without hogging precious pedalboard space. Use it to add a new voice to an old passive bass, sweeten up any amp, or put some special sauce on a particular song. Dial it in just the way you want it and send it straight to the house—pre or post-EQ—with the built-in Direct Out.

The Bass Preamp features separate INPUT and OUTPUT level controls and a 3-band EQ section with sweepable midrange—from 250hz to 1khz—for extensive tonal flexibility. It’s all delivered super clean with high headroom thanks to our own Constant Headroom Technology™, and you can use the PRE/POST EQ switch to set whether or not your Direct Out signal is affected by the Bass Preamp’s EQ section. And of course, the Bass Preamp features a GROUND LIFT switch in case you encounter ground loop hum.

The Bass Preamp is factory preset to operate in ¼” out buffered bypass and Direct Out active. For players who only want to use the ¼” out, there are two internal switches that disable the Direct Out and ¼” out buffered bypass for true ¼” out bypass mode.

Blow Torch® Distortion

By focusing the overdrive in the midrange frequencies, the Bass Blow Torch lets you retain low end thunder and high-end sizzle while distorted mids blaze a path through even the densest mix. An active 3-band EQ with 3-position mid shift lets you zero in on an incendiary tone, while the Blend knob lets you balance your distortion with direct signal to taste. And the Bass Blow Torch burns as clean as it does hot, with 18 volt performance for increased dynamic headroom, clarity and low noise even at lethal volume. True hardwire bypass circuitry means that when you switch the distortion out, it's really gone.

Phase 90

This device has found its way into many of Eddie Van Halen's recordings, adding a shimmery velocity to lead passages or a more dramatic swoosh to muted strumming. Not just for guitars; it works well with bass, keyboards and even vocals. Vary the speed from a subtle, long cycle to a fast, watery warble...and myriad vintage vibrations in between.

MXR Phase 95 Guitar Effects Pedal

The MXR Phase 95 Guitar Effects Pedal is a compact pedal that combines the legendary Phase 45 and Phase 90 circuits for the optimum Phase effect. This shrunken down mini version is equipped with a 45/90 switch that toggles between the two original phase units, while the script switch removes undesirable feedback for a subdued sound with more headroom. The familiar Speed control sets the rate of the effect and lets you achieve the perfect sound. With its scale down compact size, the Phase 95 eliminates room on your pedalboard and provides you with the ultimate Phase effect. Includes 9-volt adapter.

Further versatility comes in the form of the fuzz section’s tone controls and two switchable voices—warm and compressed or bright and aggressive—along with the Mid Level control, which allows you to give your dry signal some more punch in the midrange.

MXR Bass Preamp Review in Premier Guitar

David Abdo

August 31, 2014

Applying the descriptor “Swiss Army knife” to a piece of gear is probably overused in reviews, but if it aptly describes an instrument, amplifier, or effect pedal that offers excellent versatility, it’s a fitting one. Many effect companies offer different takes on a portable preamp—which can provide a multitude of benefits—and one of the latest units on the market comes from the design team at MXR. Their M81 Bass Preamp boasts both simplicity and flexibility, all wrapped up in a simple green box.

Just the Essentials, Please
The primary feature of the MXR M81 is its 3-band EQ with sweepable midrange. The bass and treble controls are voiced quite nicely, providing fullness that doesn’t muddy the tone and highs that aren’t harsh. Unless you obsess over midrange at Billy Sheehan-like levels, the mid and mid-frequency controls are very user-friendly, and allow a bassist to boost or mellow out the bumps, honks, and clacks of this sonic spectrum.

A significant boost with the input dial and a slight bump with the bass control began an instant tone resurrection.

Secondary features include the input and output controls. They make boosting a passive signal and achieving unity gain a breeze. Tucked cozily into the 6-knob setup are also two switches—one for ground lift and the other a pre/post for a studio-quality DI. The pedal is powered through either a 9V battery or adaptor, and it uses MXR’s Constant Headroom Technology.

Problem Solved
No matter what bass I plugged into the MXR M81, the pedal improved the overall sound of the instrument. I started by placing the pedal between a ’64 Fender Jazz and an Epifani AL112 combo set flat to hear if the preamp could breathe some life into the J’s aging pickups.


A super-functional and flexible preamp that brings out the best your bass has to offer.

Some players may find the ground lift and pre/post switches a bit difficult to reach.

A significant boost with the input dial and a slight bump with the bass control began an instant tone resurrection. Tweaking the mids brought some aggressiveness to the bridge pickup thanks to a +3 dB boost in the 500 Hz range. A little cut in the treble darkened the tone and helped create punchy and burpy bass lines, perfect for 16th-note passages.

Most surprising was how the M81 enhanced the neck pickup. It’s not that often that Jazz-bass-style players solo this side of the instrument, but with a little boost of the bass, mid (at 480 Hz), and treble, the ’64 took on a tonal character similar to its older brother P.

Despite already having its own preamp onboard, a Brubaker Brute MJX-5 benefitted from what the M81 preamp could provide. A twist of treble made the instrument’s 3-month-old strings sound fairly fresh. When I soloed the Brubaker’s Music Man-style bridge pickup and boosted the bass and mid, the M81 helped deliver a StingRay-esque voice that would be ideal for Chic bass lines and Louis Johnson disciples.

Bassists who double will probably also be impressed with the M81. I was able to dial out the harsh mids that plague both a Ned Steinberger NXT electric upright and a German upright equipped with a Fishman Full Circle pickup. It was easy to glean sounds perfect for salsa bands or jazz ensembles, from deep dub-like timbres to tones that brought out the wood of the bass.

The Verdict

Whether you’re looking to give your vintage bass a modern vibe without having to route the body, or you seek a solo-boost or tonal-tweaking device to cut through the mix, or you need a solid DI that will work well for both the stage and studio, you’re pretty much covered with the MXR M81. All of these options are at your fingertips at a price point lower than many quality onboard bass preamps, and this makes the M81 one of the better boxes in its class. I’d definitely call it a Swiss … well, you know what I mean.
