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.
How a walkie-talkie, a tiny city of circuits, and Shrinky Dinks became a mind-blowing dub box.
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.
King Tubby - Real Gone Crazy Dub (Crazy Baldhead Dub)
Listen to visionary reggae producer King Tubby work the dub siren in his composition "Real Gone Crazy Dub." The sound is addictive, freaky, and psychedelic.

MT 15 and Archon 50 Classic amplifiers offer fresh tones in release alongside a doubled-in-size Archon cabinet
PRS Guitars today released the updated MT 15 and the new Archon Classic amplifiers, along with a larger Archon speaker cabinet. The 15-watt, two-channel Mark Tremonti signature amp MT 15 now features a lead channel overdrive control. An addition to the Archon series, not a replacement, the 50-watt Classic offers a fresh voice by producing retro rock “classic” tones reminiscent of sound permeating the radio four and five decades ago. Now twice the size of the first Archon cabinet, the Archon 4x12 boasts four Celestion V-Type speakers.
MT 15 Amplifier Head
Balancing aggression and articulation, this 15-watt amp supplies both heavy rhythms and clear lead tones. The MT 15 revision builds off the design of the MT 100, bringing the voice of the 100’s overdrive channel into its smaller-format sibling. Updating the model, the lead channel also features a push/pull overdrive control that removes two gain stages to produce vintage, crunchier “mid gain” tones. The clean channel still features a push/pull boost control that adds a touch of overdrive crunch. A half-power switch takes the MT to 7 watts.
“Seven years ago, we released my signature MT 15 amplifier, a compact powerhouse that quickly became a go-to for players seeking both pristine cleans and crushing high-gain tones. In 2023, we took things even further with the MT 100, delivering a full-scale amplifier that carried my signature sound to the next level. That inspired us to find a way to fit the 100's third channel into the 15's lunchbox size,” said Mark Tremonti.
“Today, I’m beyond excited to introduce the next evolution of the MT15, now featuring a push/pull overdrive control on the Lead channel and a half-power switch, giving players even more tonal flexibility to shape their sound with a compact amp. Can’t wait for you all to plug in and experience it!”
Archon Classic Amplifier Head
With a refined gain structure from the original Archon, the Archon Classic’s lead channel offers a wider range of tones colored with gain, especially in the midrange. The clean channel goes from pristine all the way to the edge of breakup. This additional Archon version was developed to be a go-to tool for playing classic rock or pushing the envelope into modern territory. The Archon Classic still features the original’s bright switch, presence and depth controls. PRS continues to stock the Archon in retailers worldwide.
“The Archon Classic is not a re-issue of the original Archon, but a newly voiced circuit with the lead channel excelling in '70s and '80s rock tones and a hotter clean channel able to go into breakup. This is the answer for those wanting an Archon with a hotrod vintage lead channel gain structure without changing preamp tube types, and a juiced- up clean channel without having to use a boost pedal, all wrapped up in a retro-inspired cabinet design,” said PRS Amp Designer Doug Sewell.
Archon 4x12 Cabinet
As in the Archon 1x12 and 2x12, the mega-sized PRS Archon 4x12 speaker cabinet features Celestion V-Type speakers and a closed-back design, delivering power, punch, and tight low end. Also like its smaller brethren, the 4x12 is wrapped in durable black vinyl and adorned with a British-style black knitted-weave grill cloth. The Archon 4x12 is only the second four-speaker cabinet in the PRS lineup, next to the HDRX 4x12.
