MXR Joshua Ambient Echo

Like any art movement that sticks around long enough, “ambient” music has come to mean many different things. As home recording grows more accessible, it’s become a popular vehicle for quiet, introspective creations that can come together in small spaces. And when the pandemic raged, ambient music exploded both as an outlet for confined creators and as a service for stressed folk that needed to chill out. Regardless of how the form evolved beyond the prophecies and concepts of Satie, Eno, and ’60s minimalists—and some manifestations have been truly vacuous—its expansion opens a lot of opportunities for pedal builders.
MXR, for its part, hasn’t dabbled much with ambient effects. The recent MXR Reverb is, until now, probably the brand’s most ambitious effort along ambient lines. The new Joshua Ambient Echo, however, explores many such avenues by melding two delays, modulation, multiple echo divisions, octave tones, and reverb. And, yes, you can probably bet the house that, in name and sound, Joshua cheekily honors the Edge and the mega-platinum LP his band made with none other than Eno himself. See how beautifully everything intertwines in the mists of ambient space? You can reach a lot of these magical places with Joshua.
The Brink of the Abyss
Joshua’s basic voice, sans reverb, modulation, or octave, produces the kind of clean, precise digital echoes that I expect when I grab my Boss DD-3. One cool byproduct of this clarity is the way it highlights the rhythmic capabilities of the Joshua, which are a draw equal to its capacity for ambience.
Less than subliminally compelled to play a bunch of muted U2-style rhythms, I heard the Joshua snap with sharp, percussive presence in a manner evocative of the Edge’s Korg SDD-3000 sounds (check The Unforgettable Fire for a good point of reference). Predictably, the dotted-eighth and triplet modes hop and pop in a fashion that turns stupidly simple melodic lines and chord patterns into compelling riffs. But it’s when you add the second echo that these patterns really percolate. Getting these complex reflections just right can be tricky when tight rhythms are the underpinning of a riff. But getting there is hardly a chore (especially when using tap tempo), and when they come together they can add intriguing extra animation and space to simple parts.
“Predictably, the dotted eighth and triplet modes hop and pop in a fashion that turns stupidly simple melodic lines and chord patterns into compelling riffs.”
These twin-delay polyrhythms sound great in subtle, low-mix settings, too—adding dimensionality that, again, evokes the Edge’s twin SDD-3000/AC30 rig. They also benefit from the Joshua’s ability to operate at very high-to-maximum repeat and mix levels. Instead of oscillating out of control, echo patterns spool into long-to-infinite loops. In audio Clip 1 that accompanies the online version of this review, you can hear a single 12th-fret harmonic stab—played in the compound-eighth/dotted-eighth mode at maximum repeat and mix—turn into a sequencer-like pattern that’s perfect for a looper or the pedal’s freeze function.
Of course, Joshua’s most complex echoes can also unlock unusual textures and compel players to explore new dynamic techniques and approaches to songcraft. Check out Clip 2. This is a very Edge-like percussive pattern, again played on the compound-eighth/dotted-eighth division setting with a pretty aggressive mix. The first segment of the clip uses a single delay and a pattern using a heavy downstroke on the one. Played in dual delay mode, this complex tangle of echoes is a mess. But apply a light touch, add some modulation and mild octave-up content, and the same pattern of notes becomes the audio equivalent of light scattered through stained glass—producing many unexpected colors and overtones.
Generally, I’m not a big fan of octave-up content in delays and reverbs or the way they can turn otherwise engaging echo tones to cloying. The +2 octave range here can be syrupy sweet to my ears. But the pedal also has +1 and -1 octave settings, the latter of which can add ballast to a part or, at high mix and repeat settings, turn a single low E note to a haunting, endless foghorn blast. The modulation is very nice, too, adding much to the movement and harmonic makeup of the pedal’s most ambient tones, or simply working as a rich chorus at fast delay times as heard in Clip 3.The Verdict
The Edge regularly credits his old Memory Man and Korg delays for completely recasting his technique and compositional approach. And doubtless, players with free spirits and few preconceptions will find many fresh paths to wander here. That so many possibilities and complex sounds can exist alongside much more basic fare in a compact unit makes the Joshua a sensible investment—even at nearly 220 bucks. For the player that masters its complexities, it could flower into a deep well of inspiration capable of paying back that sum many times over.

Here’s part two of our look under the hood of the funky rhythm guitar master’s signature 6-string.
Hello and welcome back to Mod Garage. In this edition, we’re continuing our journey through the Fender Cory Wong Stratocaster wiring, bringing it all together.In the previous installment, the last feature on the funky 6-stringer’s signature axe that we discussed was the master volume pot and the corresponding treble-bleed circuit. Now, let’s continue with this guitar’s very special configuration of the tone pots.
Tone pot with Fender Greasebucket tone system:
This 250k tone pot is a standard CTS pot with a 90/10 audio taper found in all U.S.-built Fender guitars. The Cory Wong guitar uses the Fender Greasebucket system, which is added to the pot as a ready-to-solder PCB. The Greasebucket PCB is also available individually from Fender (part #7713546000), though you can use conventional electronic parts for this.
Fender introduced this feature in 2005 on some of the Highway One models and some assorted Custom Shop Strats. The Greasebucket name (which is a registered Fender trademark, by the way) is my favorite of Fender’s marketing names, but don’t let it fool you: Your tone will get cleaner with this modification, not greasy and dirty.
According to Fender, the Greasebucket tone circuit reduces high frequencies without adding bass as the tone knob is turned down. Don’t let that description confuse you. A standard Strat tone control does not add any bass frequencies! As you already know, with a passive system you can’t add anything that isn’t already there. You can reshape the tone by deemphasizing certain frequencies and making others more prominent. Removing highs makes lows more apparent and vice versa. In addition, the use of inductors (which is how a passive pickup behaves in a guitar circuit) and capacitors can create resonant peaks and valleys (band-passes and notches), further coloring the overall tone.

This type of band-pass filter only allows certain frequencies to pass through, while others are blocked. The standard tone circuit in a Strat is called a variable low-pass filter (or a treble-cut filter), which only allows the low frequencies to pass through while the high frequencies get sent to ground via the tone cap.
The Greasebucket’s band-pass filter is a combination of a high-pass and a low-pass filter. This is supposed to cut high frequencies without “adding” bass, which has mostly to do with the resistor in series with the pot. That resistor means the control will never get to zero. You can get a similar effect by simply not turning the Strat’s standard tone control all the way down. (The additional cap on the wiper of the Greasebucket circuit complicates things a bit, though; together with the pickups it forms an RLC circuit, but I really don’t want to get into that here.)
The standard Fender Greasebucket tone system is used in the Cory Wong Strat, which includes a 0.1 μF cap and a 0.022 uF cap, along with a 4.7k-ohm resistor in series. These are the values used on the PCB, and without the PCB it looks like the illustration at the top of this column.
Push-push tone pot with preset overwriting function:
The lower tone pot assigned to the bridge pickup is a 250k audio push-push pot with a DPDT switch. The switch is used to engage a preset sound by overwriting the 5-way pickup-selector switch, no matter what switching position it is in. The preset functionality has a very long tradition in the house of Fender, dating back to the early ’50s, when Leo Fender designed a preset bass sound on position 3 (where the typical neck position is on a modern guitar) of the Broadcaster (and later the Telecaster) circuit. Wong loves the middle-and-neck-in-parallel pickup combination, so that’s the preset sound his push-push tone pot is wired for.
The neck pickup has a dedicated tone control while the middle pickup doesn’t, which is also another interesting feature. This means that when you hit the push-push switch, you will engage the neck and middle pickup together in parallel, no matter what you have dialed in on the 5-way switch. Hit the push-push switch again, and the 5-way switch is back to its normal functionality. Instead of a push-push pot, you can naturally use a push-pull pot or a DPDT toggle switch in combination with a normal 250k audio pot.
Here we go for the wiring. For a much clearer visualization, I used the international symbol for ground wherever possible instead of drawing another black wire, because we already have a ton of crossing wires in this drawing. I also simplified the treble-bleed circuit to keep things clearer; you’ll find the architecture of it with the correct values in the previous column.

Wow, this really is a personalized signature guitar down to the bone, and Wong used his opportunity to create a unique instrument. Often, signature instruments deliver custom colors or very small aesthetic or functional details, so the Cory Wong Stratocaster really stands out.
That’s it! In our next column, we will continue our Stratocaster journey in the 70th year of this guitar by having a look at the famous Rory Gallagher Stratocaster, so stay tuned!
Until then ... keep on modding!

Your 100 Guitarists hosts are too young to have experienced SRV live. We’ve spent decades with the records, live bootlegs, and videos, but we’ll never know quite how it felt to be in the room with SRV’s guitar sound.
Stevie Ray Vaughan was a force of nature. With his “Number One” Strat, he drove a veritable trove of amps—including vintage Fenders, a rotating Vibratone cab, and a Dumble—to create one of the most compelling tones of all, capable of buttery warmth, percussive pick articulation, and cathartic, screaming excess. As he drew upon an endless well of deeply informed blues guitar vocabulary, his creativity on the instrument seemingly knew no bounds.
Your 100 Guitarists hosts are too young to have experienced SRV live. We’ve spent decades with the records, live bootlegs, and videos, but we’ll never know quite how it felt to be in the room with SRV’s guitar sound. So, we’d like to spend some time imagining: How did it feel when it hit you? How did he command his band, Double Trouble? The audience?
SRV was mythical. His heavy-gauge strings tore up his fingers and made a generation of blues guitarists work a lot harder. And his wall of amps seems finely curated to push as much air in all directions as possible. How far did he take it? Was he fine-tuning his amps to extreme degrees? Or could he get his sound out of anything he plugged into?
