MXR M134 Stereo Chorus Pedal

Add some animation and sparkle to your tone with MXR's M134 chorus pedal. Dial in Rate and Width, then crank the Intensity knob to adjust the overall level.

The gorgeous-sounding MXR M134 stereo chorus pedal will remind you how cool chorus can be. Want to add sparkle to clean-toned arpeggios? Animate strummed passages? Widen and fatten distorted power chords? This box will do it all, cleanly and quietly. Set the Rate and Width controls to your liking and then dial in as much effect as you want with the Intensity knob. You can then shape the tone even further by EQ-ing the modulated frequencies with the Bass and Treble controls. Run in mono or use the stereo outputs for a huge, vibrant sound. If you're looking to preserve the low end of your guitar tone, the MXR Stereo Chorus has got you covered with its Bass Filter button that applies the effect to the high frequencies only.

I have the MXR Black Label Chorus (the same pedal as the M234 'Analog Chorus', only with different graphics) but decided it just wasn't as impressive as all the reviews made it out to be so I opted for MXR's deluxe model stereo chorus. The difference between the two is beyond noteworthy. The BLC added a nice wobble with adjustable thickness but the crystal clear shimmer I had grown accustomed to with my slowly dying vintage Danelectro Cool Cat (the big surf green metal one from the mid 1990's) was noticeably ABSENT. I hooked up "big yellow" and was knocked out by the sound. I practice using a stereo rig with a Vox Pathfinder 10 and a Fender Rumble 25 bass amp. The Stereo Chorus made it sound like a much more expensive pair of amps. Randy Rhoads used the "original MXR" version of this pedal and when I arppegiated the 'barred B & A chords with the open E & B strings' pattern, it sounded exactly like the opening of 'You Can't Kill Rock and Roll'. Any pedal good enough for Randy is good enough for me (and you). (For a guitar I was playing a white Epiphone Les Paul Custom with Seymour Duncan "hot rods". Yeah, I'm a Randy fan!) The individual controls allow for a great many varied settings but once I dialed in the sound I got from my old Danelectro, I stopped right there. I have to say the bass filter switch is a real asset since I have a bass amp in my rig. I should take a photo in case the knobs get moved when putting the pedal away. I have to conclude my review with a shout-out read more to zZounds. I bought this pedal as a "blemished" model and it was shipped without the power supply. (All 18v MXR pedals include the power supply.) I sent an email to zZounds and received a reply 24 minutes later saying the power supply would be shipped posthaste. 24 MINUTES?! That is outstanding customer service and with service like this, zZounds will continue to be my #1 choice when buying gear.
