How—and Why—You Should Try Recording Backward Guitar Parts

Reverse Multitracking | Recording Dojo FINAL

How cutting tracks in reverse, then reversing those reversed tracks, will add zing to your mixes.

Hello and welcome to another Dojo! Since this issue is dedicated to all things acoustic, I thought I’d share a fun technique that I call “harmonic clouds.” It involves learning a section of your song backwards, recording it, reversing the new recording, and placing it back in the appropriate spot (or not!). I usually do this with acoustic guitars, but it can be applied with equal aplomb to electrics and can supercharge your creativity. Tighten up! The Dojo is now open.


We are all familiar with the sound of reverse delay. On the surface, you might be thinking, “I can do this already.” But you’d be missing out. The “harmonic clouds” technique offers many more possibilities and much more control than recording a guitar part with a reverse delay effect. In short, this technique is inspired more by the process and sounds of double tracking than using delays.

This initial track is the closest thing to a simple reverse delay but it’s not—because it is an entirely different performance, and all those subtle timing and timbral differences are there in all their glory.

By the mid-’60s, it was standard practice for the Beatles to sing all their lead vocals (and some background vocals) twice to thicken up their voices. The resulting deviations from each individual track heard together offered a slight, natural, chorusing effect as well as charming variations in timing of words, dynamics, and timbre. The net result was that the vocals stood out more on the final recordings.

However, it was time consuming. John Lennon, in particular, was always asking for a way to have the sound of “double tracking” without actually having to track the vocal twice. EMI’s brilliant studio engineer Ken Townsend devised an ingenious way of splitting the signal from just after the recording head on a Studer J37 tape machine (at 15 ips) and routing it through both recording and playback heads of the EMI BTR2 tape machine (at 30 ips), the sound from the BTR2 would then be heard at almost the same time as the sound from the Studer’s playback head [Fig. 1] With a little more help from a Levell oscillator, Townsend could varispeed the BTR2 machine with greater control (see my March 2022 article about varispeed). Thus, ADT (artificial double tracking) was born, and, FYI, Waves makes the Reel ADT plug-in ($29 street) as part of their Abbey Road Collection. But I’m going to take you a bit further than that, because we’re going to create new tracks that will increasingly differ from the original! Plus, you can always apply ADT to the new tracks later.

Let’s get started. Here are the three basic steps:

Step 1 - Learn the Progression Backwards

Take the chords from a particular section of your song (perhaps the chorus or the bridge) and learn the progression backwards, including the rhythms as well. For this example, I was working on the bridge section of a song I wrote on my album that will be released this fall called Jacob’s Well. The way I do this is by writing a chart, then reversing the order and playing it until it feels natural.

Step 2 - Create a New Track

Create a new track and then record the “new” rhythm guitar part you just learned by muting all the other tracks and playing along with the click track.

Step 3 - Reverse the Track

Reverse the track you just recorded and listen to it. Before you unmute all the other tracks and listen to how it sounds, you may have to align it a bit depending on when you stopped recording. Feel free to experiment and play around with aligning the new track in different places rhythmically and listen to how it changes the section. This initial track is the closest thing to a simple reverse delay but it’s not—because it is an entirely different performance, and all those subtle timing and timbral differences are there in all their glory.

Step 4 - Explore Your Own Music

Now we’re ready to have some real fun. Create some new tracks and repeat steps one though three, but each time play the same reversed passage in different parts of the guitar (i.e., you can change the tuning, use a capo, use only power chords, add effects, etc). As the versions pile in and you get used to the process, I think you’ll be really surprised by the results. Who knows, you might even start trying this with all kinds of instruments! Just remember to always serve the song and stay true to the emotional content you want to use these tracks to achieve. Most often for me, less is more.

Until next month, blessings, and keep sharing your gifts with the world. Namaste.

What if you could have the best of both—or multiple—worlds? Our columnist investigates.

This column is a fun and educational thought experiment: What if I took inspiration from the well-known Fender amps out there, combined the best from them, and applied a few of my own twists? After all, this is how amps developed. I read somewhere that “Fender made the first Marshall, and Marshall made the first reissue Fender.” It's funny, because it's true: The Marshall JTM45 was based on the narrow-panel tweed Fender Bassman 5F6-A.

Over the decades with Hüsker Dü, Sugar, and solo, Bob Mould has earned a reputation for visceral performances.

The 15th studio album from the legendary alt-rocker and former Hüsker Dü singer and 6-stringer is a rhythm-guitar record, and a play in three acts, inspired by sweaty, spilled-beer community connection.

Bob Mould wrote his last album, Blue Heart, as a protest record, ahead of the 2020 American election. As a basic rule, protest music works best when it's shared and experienced communally, where it can percolate and manifest in new, exciting disruptions. But 2020 wasn’t exactly a great year for gathering together.

Guitar: The Italian Hybrid

Reader Federico Novelli constructed this hybrid guitar from three layers of pine, courtesy of some old shelves he had laying around.

Through a momentary flash, an amateur Italian luthier envisioned a hybrid design that borrowed elements from his favorite models.

A few years ago, at the beginning of Covid, an idea for a new guitar flashed through my mind. It was a semi-acoustic model with both magnetic and piezo pickups that were mounted on a soundboard that could resonate. It was a nice idea, but I also had to think about how to make it in my tiny cellar without many power tools and using old solid-wood shelves I had available.

I have been playing guitar for 50 years, and I also dabble in luthiery for fun. I have owned a classical guitar, an acoustic guitar, and a Stratocaster, but a jazz guitar was missing from the list. I wanted something that would have more versatility, so the idea of a hybrid semi-acoustic guitar was born.

I started to sketch something on computer-aided design (CAD) software, thinking of a hollowbody design without a center block or sides that needed to be hot-worked with a bending machine. I thought of a construction made of three layers of solid pine wood, individually worked and then glued together in layers, with a single-cutaway body and a glued-in neck.

For the soundboard and back, I used a piece of ash and hand-cut it with a Japanese saw to the proper thickness, so I had two sheets to fit together. Next, I sanded the soundboard and bottom using two striker profiles as sleds and an aluminum box covered in sandpaper to achieve a uniform 3 mm thickness. A huge amount of work, but it didn't cost anything.

“It was a nice idea, but I also had to think about how to make it in my tiny cellar without many electric tools and out of old solid-wood shelves I had available.”

The soundboard has simplified X-bracing, a soundhole with a rosewood edge profile, and an acoustic-style rosewood bridge. For the neck, I used a piece of old furniture with straight grain, shaped it to a Les Paul profile, and added a single-action truss rod. The only new purchase: a cheap Chinese rosewood fretboard.

Then, there was lots of sanding. I worked up to 400-grit, added filler, primer, and transparent nitro varnish, worked the sandpaper up to 1,500-grit, and finally polished.

Our reader and his “Italian job.”

For electronics, I used a Tonerider alnico 2 humbucker pickup and a piezo undersaddle pickup, combined with a modified Shadow preamp that also includes a magnetic pickup input, so you can mix the two sources on a single output. I also installed a bypass switch for power on/off and a direct passive output.

I have to say that I am proud and moderately satisfied both aesthetically and with the sounds it produces, which range from jazz to acoustic and even gypsy jazz. However, I think I will replace the electronics and piezo with Fishman hardware in the future.
