State of the stump: Our columnist built this dub-inspired oscillator inside the shell of an old walkie-talkie bearing Radio Shack's Realistic brand name.
My phone has become a repository of gut shots and glamour shots of my pedal builds. Once a year or so, when it gets full, I dump the photos onto a hard drive for safe keeping. Every time I do, it turns into an all-day trip down memory lane. I go back—all the way back—to when I first started building pedals, and I look at my progression from then until now. I find it so rewarding to have a visual journal of all the work, love, and intention that I put into them. It's a representation of my learning journey and a reminder of how many friends I have made along the way.
Recently, as I was scrolling through, I found photos of what remains my favorite build to this day. I want to share my experience building it. As some of you know, I love to make guitar pedals out of broken, old electronic equipment. It's honestly my passion. In particular, I enjoy gutting busted walkie-talkies and building fun things inside. The old steel cases just look so cool! This particular Realistic Rover-1500 walkie-talkie became a dub-siren-turned-guitar-pedal. I named it the Loe-Fi Dub Siren. You can hear it on Instagram.
A dub siren is a type of synthesizer used predominantly in dub reggae. It is usually a relatively simple oscillator, housed in a box, often allowing for a variety of waveforms to be altered by turning potentiometers controlling pitch, rate, and other parameters. Dub sirens are frequently activated by a button and sometimes have the functionality to toggle between continuous synthesis with one button press or sound-emission-only when the button is held.
I just love it when there is an uninterrupted, smooth flow to a rather complicated build.
I built this oscillator circuit and added a small delay circuit to it as well. It sounded really cool and was fun to jam on during testing. I decided to take it one step further and add a sweep filter so that it could sound just like the King Tubby records I took my inspiration from. After I had it all finished, I had a thought: What if I add an input jack? Then, I could play guitar, or whatever, through it and play along with the oscillator. It took some figuring out, but eventually I got it all working. It was a pretty complicated build in the end.
I took my string-of-many-circuits that was ready to go and began the process of figuring out where everything was going to fit inside the walkie-talkie enclosure. This is probably the biggest challenge of all when building inside salvaged enclosures. They are often molded and, therefore, have a lot of odd protrusions to work around when considering where all of the circuit boards can be mounted. I also needed to figure out where the controls would go.
Next, came the drilling. Let me tell you, drilling steel is no fun! Not for me, anyway. Why did I have to put so many controls on this thing? After about an hour of careful drilling, the walkie-talkie was ready for population. I carefully followed my notes and built a little city inside. Then, I moved onto wiring. Many folks who build electronics loathe the wiring process, but I love it and enjoy the challenge of doing it neatly. Nothing gets me as excited as a gut shot with really tidy wiring.
This cool, jungle-themed badge on the side of Aisha Loe's Loe-Fi Dub Siren was painstakingly made from Shrinky Dinks. It took about 20 tries to get right.
After all the hardware and circuit boards were mounted, I tested the finished work. I made a few little last minute tweaks and deemed it ready for knobs. I ridiculously obsess over knob selection. I think it's a pretty common thing among pedal builders, actually. The knobs tie the whole thing together visually. A lot of thought goes into not only aesthetics, but also how they feel. They're going to get touched a lot, so they should feel nice!
As a finishing touch, I made a name badge for the finished pedal … out of Shrinky Dinks! (If you don't know that these are, google them. They're cool!) Yes, you read that correctly. I don't know why that idea popped into my head, but it did. So, I went with it. I learned that it takes about 20 tries to get it right! I vowed to never do that again. It does look pretty sweet, though.
I learned so much in the process of putting this pedal together. Sometimes my experiments lead me down paths that dead end. I learn a lot, whether it becomes a pedal at the end of my journey or not. This one gave me a win at every turn. Every idea and modification I had for it worked out so well. I just love it when there is an uninterrupted, smooth flow to a rather complicated build. The experience of building this dub siren is a cherished memory, and the pedal now belongs to one of my favorite musicians of all time. Dreams do come true! This build will always remind me of that.

There’s nothing cooler than using a Leslie cabinet in the studio, and few things worse than having to lug one to gigs. The famed Leslie 981, for example, weighs nearly 150 pounds. Enter the rotary speaker pedal—an easy-on-the-back alternative for players who are looking to conjure Leslie-derived guitar sounds employed on classic records by Hendrix, Pink Floyd, Led Zeppelin, the Beatles, and others.
California Roller
There are a lot of good options for on-the-floor rotary pedals between $99 and $549. At $299, Keeley Electronics’ new I Get Around Rotary Simulator falls in the middle of the pack on pricing but has an array of functions that make it competitive with costlier examples. The I Get Around is part of a collaboration between Keeley, JHS Pedals, and Benson amps, dedicated to creating five limited-edition effects in tribute to the Beach Boys. I can’t recall many Beach Boys tracks with Leslie-style guitar, but Brian Wilson did use the effect on brother Carl’s guitar on 1965’s “You’re So Good to Me,” and a year later on the song “Pet Sounds.”
At 5" x 4" x 2", the I Get Around is a little larger than the average stompbox, but that’s necessary to accommodate the three big dials on top (blend, drive, and speed) as well as the on/off (which also works to select true bypass or buffered mode) and slow-fast switches, plus the stereo inputs and outputs. Using two amps in stereo makes the flutter and warble of the rotary sound more pronounced and immersive. It’s truly psychedelic. There’s also a toggle that adds a 4.5 dB mid-boost, which fattens and tightens the tone enough for me to simply want to leave that boost engaged all the time.
How I Got Around
I ran the I Get Around—powered by a 9V barrel connector at 130 mA— through a pair of Carr amps, playing a Gibson Les Paul Standard and a PRS SE Silver Sky, and blended the pedal with overdrive, fuzz, and delay as I experimented. I love the extra-large size of the speed control, which let me adjust the rate of simulated rotation at a whim with my shoe. The speed’s range is .06 Hz to .6 Hz, with 1 Hz being one revolution per second, and all the speed settings sound great and conjure the vibes you’d want from a Leslie, from velvet-painting dreamscapes to edgy, breathless Robert Ward- and David Gilmour-style psychedelic blues. Add a little delay and the sound becomes spongier and stranger, but too much, of course, can turn things to muck, as can an overbearing fuzz.
The drive control is a subtle overdrive that simulates a pushed 6550 and 12UA7 tube. At moderate amp volume, it doesn’t add much discernable grit until about 9 o’clock. Past 2 o’clock it rolled off enough top end to make my guitar sound less potent. But between those demarcations lies a very sweet spot for adding beef. The blend control starts being effective at about 8 o’clock, when the first hints of the rotary sound become a backdrop for the guitar’s voice, and then it's just a matter of turning up to taste—including cranking all the way clockwise to entirely eliminate your core guitar sound in favor of the rotary effect alone. For my taste, the best overall sounds were achieved with subtle-to-pronounced blends, between 9 o’clock and a bit past 2, that added rotary effect to my always-present basic guitar tone, thickening, supporting, and swirling behind it.
The slow-fast switch is all about drama. It allows toggling between two speed settings, and when it’s held down it stops the rotating speaker effect, which resumes when the switch is pressed again. The ramp rate can be customized as well. I like it slow, so the activation of the swirl is audible.
The Verdict
Keeley’s new I Get Around Rotary Simulator commands all the essential sounds you’d want from an actual Leslie. Unlike some pedals in its price range, it’s got stereo outs, which, to my thinking, are essential, because the rotary effect sounds best through guitar amps run in stereo. Also, the deep functionality beyond the basic adjustments of the three topside dials is attractive, adding more Leslie-like realism. There are cheaper alternatives, but to find competitive or better examples, you’ll need to reach deeper into your pockets.
