If you're a guitar modder, you probably already have most of the simple tools needed for this unique pedalboard project.
Hello, and welcome to my first DIY project for Premier Guitar. I'm going to explain how to make a battery-operated power supply for your pedalboard (Image 1). We'll be using a cordless drill battery for power and a few other items that you might already have lying around. All of the parts needed for this project can be easily found and purchased online.
Why would you want to use a drill battery to power your effects pedals? By powering your effects with a battery, you eliminate the potential for noise caused by bad wiring in your home or in a venue, it eliminates possible ground loops as well as a cord to trip over, and it expands your possibilities for placement of your pedalboard. Drill batteries are tough, easily rechargeable, and will last a really long time before needing a recharge. They just pop in and out of their charger and will pop in and out of your power supply. If you already have a couple spare batteries, the cost of this build is small. Spare batteries can be purchased online if you already have a charger, or you can even buy batteries and a charger.
If you've been modding the wiring of your guitars, you probably have the tools and skills necessary to build this project.

You'll need a good soldering iron and solder, a drill, needle-nose pliers, a multimeter, and, of course, eye protection. If you're like me, you'll also need reading glasses to see what you're doing. This build is pretty simple and easy to understand, as you can see in the wiring diagram shown in Image 2. The orange square is the back of the common 3PDT footswitch found in most boutique stompboxes. I used a 3PDT footswitch, but a 2PDT footswitch or any toggle switch will also work for this project.
The two most important items we need, other than a battery, are a battery adapter and a buck converter, sometimes called a voltage converter.
Image 3
The battery plugs into the adapter, just like it plugs into a drill, and has two wires that let us connect to the battery's power. Battery adapters are made for several brands of drill batteries. I use Milwaukee but Makita and DeWalt will also work for this project. I bought my battery adapter (Image 3) for about $16 from Amazon.
The buck converter lets you adjust (or "step down") the voltage coming from the battery to 9 volts, which is the voltage you want for most pedals. These units are also cheap. I bought a pack of four, just in case I ruined one. Get one that will handle at least 25 volts on the upper range and goes down past our target voltage of 9 volts. Also, check how much current it can handle: 3 to 5 amps should be plenty.
Get a buck converter that will handle at least 25 volts on the upper range and goes down past our target voltage of 9 volts.
Image 4
The buck converter I bought is about 2" by 1" (Image 4), with connections for DC in and DC out. The small brass screw on top of the blue rectangular box is the adjustment. On mine, turning the screw counterclockwise drops the output voltage. It takes a really small screwdriver to fit the adjustment screw, and a lot of turns to get it down to 9 volts.
The buck converter I bought is good for 3 amps of electric current. So how much current will your pedals draw? I found a good list of different pedals and their power draw on Stinkfoot.se. The four pedals I've been using lately draw a total of 113 mA, or .113 of an amp. It's important to note that stompboxes draw power whenever there is a guitar cord plugged into them, even when switched off. The footswitch on a pedal just routes the signal around the circuitry and doesn't stop the power draw. This is why we're putting a footswitch on our project, so we can turn off the power. We'll also incorporate an LED to remind us when the power is on.
We'll use a basic stompbox enclosure for this project. I used one that measures about 2 1/4" x 4 1/4", and it came in a box of three. The box came with a special stepped drill bit that makes holes for things like jacks, switches, and LEDs, and a helpful list of which steps work for different parts. A piece of masking tape wrapped around the drill bit at the appropriate step will help you drill the right-sized hole without going too far.
What Else Will We Need?
- One 3PDT footswitch (a 2PDT footswitch will also work)
- An LED and mounting bezel
- One 4.7k (drop-down) resistor
- A barrel jack, compatible with your power cord
- Two colors of hookup wire, 22 AWG or 24 AWG
- Standoffs to mount the buck converter, or some silicone caulk
- Three or four nuts and bolts to mount the battery adapter
- And lastly, we will need that old daisy chain power cord I know you have lying around, to power your pedals.
Heat-shrink tubing is not strictly necessary, but it will make your build a lot neater than using electrical tape. Once you buy some, you'll find many uses for it and it'll come in handy often. I got a bag with a bunch of different diameter pieces for a couple bucks, and it's lasted me several years.
Bolt-mount the battery adapter to the bottom of the enclosure.
Image 5
Now let's get started. You can see all the parts and wiring fit in the enclosure pretty easily (Image 5). Mark where the holes go carefully. Use the shortest bolts you can, so they don't interfere with the wiring, making sure to leave room to access the screws that hold the enclosure together.
Next, mark where to drill the holes for the footswitch, LED, and jack.
Image 6
You'll need one more hole to bring the wires from the adapter into the enclosure: Put that on the end opposite the jack. Make sure to sand this last hole nice and smooth around the edges so it won't abrade the wire. I put my jack hole about halfway between the top and bottom of the enclosure and that left me plenty of room for wiring. Make sure you leave enough room between the jack and footswitch (Image 6). Now we can mount the jack, footswitch, and LED bezel.
At this point, you just need to follow the diagram to wire things up. I used 22 AWG wire and found it a little bit cumbersome to fit it into a few of the tighter spaces and get it soldered. On that note, 24 AWG wire would probably be fine. It should be good for around 1.4 to 3.5 amps, depending on if it's stranded or solid core. To give you an idea, 1.4 amps is more than 10 times the current of what my four pedals draw.
I mounted another jack for 18-volt output, just in case I ever get an 18-volt pedal. (This would also require a second buck converter.) After wiring it up, however, I found my 18-volt batteries are actually around 20 volts, so I removed the wiring.
If you don't have standoffs for your buck converter, you need another way to mount it to the inside of your enclosure.
Image 7
I used silicone caulk to glue mine to a thin piece of wood. I used alcohol to clean the enclosure where I put the silicone, to make sure it would stick. After the silicone was dry and I wired up the converter, I used more silicone to glue it to the enclosure (Image 7).
Cut the wires from your battery adapter to a shorter length, feed the wires from the input of your buck converter through their hole in the enclosure, and solder them to the battery wires.
Image 8
This is where your heat-shrink tubing will come in handy. Use some more of that silicone to anchor the wires in the hole after you know everything works. And be sure that you wire your jacks so the center is negative (Image 8).
The LED needs a resistor soldered to the positive leg in series to operate.
Image 9
The positive leg is the longer one. Fit the LED legs through the plastic-mounting sleeve that came with the bezel before you solder on your resistor (Image 9). The LED will then just push into the bezel. If your LED is close enough, you can solder the other end of the resistor to the switch, like I did. You can use wire if it's too far. The other lead from the LED goes to the ground from the battery. It's worth noting that the value of the drop-down resistor depends a lot on the type and color or LED. We're using a 4.7k resistor, which works fine with a blue standard LED. For all other LED colors and types, the resistor type can be recalculated online. A good resource for this is: https://www.muzique.com/schem/led.htm.
If you soldered everything up correctly, you should be good to go! I have two different-sized drill batteries, and even the small ones will power my pedals for nine hours. I would suggest turning your power supply on and testing with your multimeter before plugging in any of your pedals, taking care that the polarity of your output is correct.
How could you modify my design? You could use a larger enclosure and more jacks, allowing you to power each pedal with its own cable. Instead of a larger enclosure, you could make a separate box with lots of power jacks. A second buck converter could allow for 18-volt power. Maybe it would make sense for you to mount your battery adapter directly to your pedalboard and mount the stompbox enclosure separately. Let me know if you have other ideas in the comments section online.
For me, this was an enjoyable switch from my usual projects. I have a lot of leftover parts, so I guess it's time to start thinking about what to make next.PQ: "I would suggest turning your power supply on and testing with your multimeter before plugging in any of your pedals, taking care that the polarity of your output is correct."

The author, middle, with bassist Ross Valory (left) and Steve Smith (right) of Journey.
Do you know who’s hanging around your gigs? Our columnist shares a story about the time Journey’s bassist was in the audience during soundcheck.
I’ve always loved what I do for a living. Even long before it became a career, doing the work every day to get better was something I fell in love with right away. As a result, I’ve never had any issues with stage fright or nerves when it comes to performing—even if there are some mega-influential or important musical people in the room.
Luckily, throughout my career, I usually only find out if there’s been someone major in the audience after the show. I’m not very social on tour these days. I’m the last one to soundcheck or show and the first one out of the venue afterwards. I’m often asleep in the hotel before some of the rest of the band have even left the venue.
But once in a while, I do get caught off guard—and this little story from a night on tour last week highlights how you just never know who’s listening … or watching.
I’ve been playing with Steve Smith (former drummer of Journey and inductee of the Rock & Roll Hall of Fame) for over 10 years, first as sidemen with Mike Stern in a band with Randy Brecker, and for the past five years as a member of Steve’s band Vital Information. Throughout that entire time—hundreds of shows, rehearsals, soundchecks, recording sessions, and clinics—I haven’t once played a Journey bass line around him.
It’s that thing of being way too on the nose to even hint at. Knowing that the Journey chapter of Steve’s life is musically very much in the past, it honestly just never crossed my mind. So, what on earth possessed me to start playing the bass line to “Any Way You Want It” during soundcheck in Oakland last week?!
I don’t even get through the first two bars of the song when I hear, “Looks like I’ve been rumbled….” I look up, and there’s Ross Valory, the original bass player for Journey.
I had never met him. I had no idea anyone besides the band and the crew were even in the venue during soundcheck. Aside from the embarrassment of doing that in front of one of your bass heroes, it really got me thinking about how you just never know who is listening.
I don’t know who the phrase “be ready when the luck happens” should be credited to—or if that’s exactly how it was originally said—but I’ve thought about little else since my Ross Valory moment. If you’re considering a career in music, or working to further the one you already have, it might be something worth thinking about for yourself.
“I had no idea anyone besides the band and the crew were even in the venue during soundcheck. Aside from the embarrassment of doing that in front of one of your bass heroes, it really got me thinking about how you just never know who is listening.”
Like I said before, I’ve been in love with the work since the beginning. I still set aside vast amounts of time every day to practice and work on my music. I’m constantly tinkering with my goals, large and small. I’m realistic about the time it will take to reach them, the work I need to do to get there, and the fact that some goals may well change over time—and I have to be totally okay with that and adapt as quickly as possible.
The success of the work and the attainment of the goal is also going to rely at least a little bit (and if I’m being honest, sometimes a lot) on luck. Being ready to capitalize on luck involves constantly updating my daily routine. I have to find the balance between working on very specific elements of my playing for long periods of time, and letting them go once I know they’re an internal part of my vocabulary.
Jazz pianist Chick Corea talked about memorizing versus knowing a piece of music. When you read through a chart and start to memorize it, you’re essentially just taking the music from the sheet and creating a picture of it in your brain. You then end up looking for that picture the next time you want to play it—and all you’ve done is take away the physical paper while keeping the concept of reading. That’s not knowing the material like it’s a natural part of your vocabulary. The repetition I aim for in my daily routine is what helps me play the language of music as fluently as I speak English.
The confidence gained by putting in the work can make you so much more ready for your moment than you’ve ever been before.
Set goals, love the work, and always be ready.
You never know who’s listening….
The veteran Florida-born metalcore outfit proves that you don’t need humbuckers to pull off high gain.
Last August, metalcore giants Poison the Well gave the world a gift: They announced they were working on their first studio album in 15 years. They unleashed the first taste, single “Trembling Level,” back in January, and set off on a spring North American tour during which they played their debut record, The Opposite of December… A Season of Separation, in full every night.
PG’s Perry Bean caught up with guitarists Ryan Primack and Vadim Taver, and bassist Noah Harmon, ahead of the band’s show at Nashville’s Brooklyn Bowl for this new Rig Rundown.
Brought to you by D’Addario.Not-So-Quiet As a Mouse
Primack started his playing career on Telecasters, then switched to Les Pauls, but when his prized LPs were stolen, he jumped back to Teles, and now owns nine of them.
His No. 1 is this white one (left). Seymour Duncan made him a JB Model pickup in a single-coil size for the bridge position, while the neck is a Seymour Duncan Quarter Pound Staggered. He ripped out all the electronics, added a Gibson-style toggle switch, flipped the control plate orientation thanks to an obsession with Danny Gatton, and included just one steel knob to control tone. Primack also installed string trees with foam to control extra noise.
This one has Ernie Ball Papa Het’s Hardwired strings, .011–.050.
Here, Kitty, Kitty
Primack runs both a PRS Archon and a Bad Cat Lynx at the same time, covering both 6L6 and EL34 territories. The Lynx goes into a Friedman 4x12 cab that’s been rebadged in honor of its nickname, “Donkey,” while the Archon, which is like a “refined 5150,” runs through an Orange 4x12.
Ryan Primack’s Pedalboard
Primack’s board sports a Saturnworks True Bypass Multi Looper, plus two Saturnworks boost pedals. The rest includes a Boss TU-3w, DOD Bifet Boost 410, Caroline Electronics Hawaiian Pizza, Fortin ZUUL +, MXR Phase 100, JHS Series 3 Tremolo, Boss DM-2w, DOD Rubberneck, MXR Carbon Copy Deluxe, Walrus Slo, and SolidGoldFX Surf Rider III.
Taver’s Teles
Vadim Taver’s go-to is this cherryburst Fender Telecaster, which he scored in the early 2000s and has been upgraded to Seymour Duncan pickups on Primack’s recommendation. His white Balaguer T-style has been treated to the same upgrade. The Balaguer is tuned to drop C, and the Fender stays in D standard. Both have D’Addario strings, with a slightly heavier gauge on the Balaguer.
Dual-Channel Chugger
Taver loves his 2-channel Orange Rockerverb 100s, one of which lives in a case made right in Nashville.
Vadim Taver’s Pedalboard
Taver’s board includes an MXR Joshua, MXR Carbon Copy Deluxe, Empress Tremolo, Walrus ARP-87, Old Blood Noise Endeavors Reflector, MXR Phase 90, Boss CE-2w, and Sonic Research Turbo Tuner ST-200, all powered by a Voodoo Lab Pedal Power 2 Plus.
Big Duff
Harmon’s favorite these days is this Fender Duff McKagan Deluxe Precision Bass, which he’s outfitted with a Leo Quan Badass bridge. His backup is a Mexico-made Fender Classic Series ’70s Jazz Bass. This one also sports Primack-picked pickups.
Rental Rockers
Harmon rented this Orange AD200B MK III head, which runs through a 1x15 cab on top and a 4x10 on the bottom.
Noah Harmon’s Pedalboard
Harmon’s board carries a Boss TU-2, Boss ODB-3, MXR Dyna Comp, Darkglass Electronics Vintage Ultra, and a Voodoo Lab Pedal Power 2 Plus. His signal from the Vintage Ultra runs right to the front-of-house, and Harmon estimates that that signal accounts for about half of what people hear on any given night.
