Dig into the weird wiring of the Hofner Beatle Bass and 172 guitar.
Hello and welcome back to Mod Garage! In this column, we will have a look at the famous HA2B control-panel wiring from the German Höfner company (often written as “Hofner” without the German umlaut). The control plate became famous on the Höfner violin bass—the model 500/1 that was released in 1956 and is often referred to as the “Beatle Bass” because of Paul McCartney.
Höfner also used this wiring on a lot of their early solidbody electric guitars, like the famous model 172. These models were covered in colorful vinyl rather than receiving a paint job. The demand for electric guitars was very high in the ’60s, and a paint job was very time-consuming and expensive, so this method was a welcome alternative to cut costs and save time. The vinyl is still an eye-catcher today.
My first real electric guitar was such a Höfner, a later model without the control plate, but still covered in gorgeous red vinyl. Eventually, I removed the vinyl and put some dilettantish paint job on it. When I think about it today, I feel like a lemon.
Frank Meyers recently wrote a cool column about the Höfner company and its history, which appeared in PG’s March 2023 issue, so if you want to find out more about them, please check it out.
So, let’s have a look at the control plate and its very special wiring. It might be considered weird from today’s perspective, but at the time, this wiring was state of the art. The control plate itself and the fancy “tea cup” knobs are still available today—it is called HA2B with an additional letter indicating the color of the plastic control plate, e.g. B (black), C (cream), T (tortoise), and so on.

This wiring is designed for a guitar with two pickups and sports an individual on/off switch and volume control for each, plus a rhythm/solo switch, resulting in a total of two pots and three switches. Please note that the plate is labeled in English and not in German, which clearly shows that Höfner was targeting the international market while still selling large quantities inside Germany.
Here is a short summary of what the individual controls are doing, using Photo 2 as our reference:
• neck pickup volume pot
• solo = full output signal / rhythm = output attenuated to about 70 percent
• bass off = bridge pickup on / bass on = bridge pickup off + treble filter
• treble off = neck pickup on / treble on = neck pickup off + bass filter
• bridge pickup volume pot
The way the bass and treble switches are wired up is the real weird part. Back in the day, a neck pickup was often referred to as the bass pickup and the bridge pickup the treble pickup. In this case, the bass switch is for the treble pickup and vice versa. So when the bass switch is off, the bridge pickup is on; when it’s on, the bridge pickup is off. And when the treble switch is off, the neck pickup is on; when it’s on, the neck pickup is off.
This results in the following: When both switches are in the off position, both pickups are engaged (in parallel), and when both switches are in the on position, both pickups are disabled, which works like a kill switch to mute the whole guitar.
This is, for sure, one of the fanciest guitar wirings ever. But believe me, compared to some wirings that were used in the electric guitars of the Musima company in the former GDR, this one here is as harmless as can be.
"There is no law against experimenting with the values of the caps and resistors to tweak the tone to your personal preferences."
Let’s have a look what’s under the hood:
2 x 250k audio pots
3 x DPDT slide switches
1 x 270k + 1 x 100k resistors for the solo/rhythm switch
1 x 0.01 uF treble cap
1 x 0.1 uF bass cap + 1 x 8.2k resistor
You can use any cap and resistor you want. I like to use small film caps and 1/4-watt metal film resistors. It’s nice working with these parts because they are small enough to fit the control plate.
The wiring works as follows:
Solo/rhythm switch: While the solo position has full signal output, the rhythm position engages two resistors to reduce the output to approximately 70 percent by bleeding some signal to ground.
Bass switch: In the on position, the bass capacitor and the resistor filters some highs off to ground.
Treble switch: In the on position, the treble capacitor filters some bass off to ground.
So, here we go for the wiring:

This is the real deal circuit that Höfner used in the early ’60s. The modern overhauled wiring of the HA2B circuit looks very similar, but uses a 0.1 uF treble cap and has no additional resistor in-line with the bass cap. To my ears, the vintage version sounds better, but this is a matter of taste and there is no law against experimenting with the values of the caps and resistors to tweak the tone to your personal preferences.
I would like to thank Baptiste Zermati from the L’instrumenterie company in France for the photos of the vintage Höfner 172—a big shoutout to him.
That’s it! Next month, we will talk about the brand new PRS “Dead Spec” Silver Sky wiring for John Mayer and how you can adopt this for your own Stratocaster, so stay tuned!
Until then ... keep on modding!
A hot-rodded Melody Maker, a pair of Deluxe Reverbs, and a custom-built ’board power this funk funhouse.
Ryan Lerman is the cofounder of Los Angeles-based dynamic funk project Scary Pockets. The musical collective has been crushing it on Youtube since 2017, and eventually they decided to take their show on the road—a shift that’s turned them into a celebrated and successful touring act. Lerman met up with PG’s John Bohlinger before Scary Pockets’ Nashville show at the Brooklyn Bowl to talk through his current touring rig.

On this leg of the tour, Lerman is rolling with backline amps—generally two Fender ’68 Custom Deluxe Reverbs.
Funk on the Floor
For his stompbox kingdom, Lerman tapped Dave Phillips at L.A. Sound Design to build him a road-ready board. First up, Lerman runs a 1/4" cable from his guitar right into a 29 Pedals Euna. From there, the signal runs the gauntlet through: an Electro-Harmonix Superego, WMD Geiger Counter, Rainger FX Reverb-X, Ross Compressor, Klon Centaur, JHS SuperBolt, JAM Pedals WaterFall, Non-Human Audio Slow Loris, Eventide H9, Strymon Flint, Empress Superdelay, Sonic Research Turbo Tuner ST-300, Fairfield Circuitry Shallow Water, Mooer Slow Engine, Surfy Industries SurfyVibe, and a Lehle volume pedal.

College internships can run the gamut. They can lead you into a career or dissuade you from pursuing one altogether. In 2004, while still attending the New England Conservatory of Music in Boston, singer Rachael Price, bassist Bridget Kearney, founding guitarist Mike “McDuck” Olson, and drummer Mike Calabrese joined forces to perform as what they dubbed a “free country band,” where they intended to play country music in an improvised, avant-garde style. As it goes with many college-years experiments, it didn’t stick, but the fervid foursome pushed forward in continuing to develop their own sound. They quickly graduated to a bona fide band cultivating a buzz with infectious concerts, creative covers, and complex, groovy originals. Through their mutual influences and complimentary counterpoints, their sound matured into a harmonious fusion, as if Berry Gordy produced the Beatles in Nashville’s RCA Studio.
If starting a band and shaping their sound was an internship and bachelor’s degree, self-releasing records and organizing U.S. tours would be their master’s and doctorate. They self-released 2007’s In This Episode... and 2008’s Promises, Promises before joining Signature Sounds, who put out 2010’s Lake Street Dive and 2014’s Bad Self Portraits. (The latter slotted them on the Billboard charts—No. 18 in the 200 and No. 5 in Top Rock Albums.) They then signed to Nonesuch, where they’ve dropped three more albums—most notably 2016’s Side Pony, which put them atop the Top Rock Albums chart, while 2021’s Obviously netted them their highest single, with “Hypotheticals” hitting No. 2 on the Adult Alternative Airplay chart.
And while the band has continued to evolve, experiment, and expand their signature sound, they have kept to their core identity—having fun. They seem never to miss a Halloween dress-up show, and still aren’t gun-shy about covering classics and making them their own. Setlists are often littered with audience requests and reinterpretations of the Beatles, Hall & Oates, George Michael, Bonnie Raitt, Elvis, Shania Twain, the Pointer Sisters, the Jackson Five, the Kinks, Steely Dan, Annie Lennox, Sly & the Family Stone, and countless others.
The afternoon before their second consecutive sellout at Nashville’s Ryman Auditorium, Lake Street Dive’s Bridget Kearney and touring guitarist James Cornelison welcomed PG’s Chris Kies on stage for a casual gear chat. Kearney explained how she uses a pair of octave pedals through her standup double bass, and what she’s doing with four tuners! Plus, she explains what restarted her slow-burn courtship with electric bass. Then, Cornelison walks us through his setup, which includes leftover pieces from retired guitarist Mike “McDuck” Olson and a ratty pickup bought off a former PG staffer. It both honors the band’s catalog and carves his own musical fingerprint.

All About That Bass
Bridget Kearney is known for almost exclusively using a standup double bass on stage and in the studio with Lake Street Dive. (As you’ll see in a minute, she’s fostering her connection with electric bass.) She’s been thumping on this one since LSD took shape. She acquired the 50-year-old carved double bass (all solid-wood construction) from fellow bass player and friend Ben Davis. When she received it from Davis, he had already added a David Gage Realist LifeLine pickup, but she’s opted to add and amplify via a Fishman Full Circle Upright Bass Pickup (“the heart of the tone”) and a Pierre Josephs String Charger magnetic transducer (“helpful getting extra juice to cut through when playing with a full band”). The Fishman provides a pure, clean signal to FOH, while the String Charger handles all the effects Kearney puts on her instrument. It’s been years since she’s changed strings, but she thinks they’re D’Addario Helicore Orchestral bass strings.
Playing Paul
In Brooklyn for Halloween 2020, Lake Street Dive recreated the iconic Beatles rooftop concert. In doing so, the entire band doubled down to look the part (wigs, sideburns, and shaggy coats included). To be as authentic as possible, Kearney borrowed a friend’s Höfner for the performance. She enjoyed the playing experience and wanted to further investigate the electric bass, then bought this Höfner Limited Edition H500/2-RLC-O Club Bass. “Before this, I hadn’t played electric bass for nearly 20 years. It took me to the age of 35 to think, ‘I wonder if electric bass could be a cool thing?’ Höfner and that rooftop concert was my gateway drug back to solidbody electric basses.”
New Friend
Kearney landed this brown beauty just a few months ago while instrument-shopping in Seattle. She had saw this 1975 Fender P bass on a store’s online inventory, but Bridget realized after arriving that she had went to the wrong store. However, the “wrong” store had a 1969 P she couldn’t pass up. Even after buying a vintage gem, months later, the above ’75 was still haunting her. So, the next time she visited Seattle, Kearney went to the “right” store and made the purchase. She hasn’t used it in the studio yet, but during this run of shows, she brought it for the band’s cover of “Love Doctor” from her 2017 solo record Won’t Let You Down. (The Cookin’ Outlaws stickers were put on prior to the score, and Bridget notes they are a part of the instrument’s charm.)
Bridget Kearney’s Pedalboard
“My pedalboard is a little bit ridiculous. It’s composed of four Boss tuners [laughs],” concedes Kearney. Unraveling the 4-tuner conundrum, she explains that she uses a pair of TU-3s for each pickup on her standup bass. The ingenious silver plate allows her to mute both signals with one kick. A passive TU-2 stays on all the time to help her play the fretless standup as close to in tune as possible. And the fourth Boss tuner is for her electric basses. Her duo of Electro-Harmonix Micro POGs each have a specific duty—one goes low (for “Good Kisser”), and one goes high (for solos and melodic lines). An Ibanez TS9 Tube Screamer adds some sting to the double bass for “Bobby Tanqueray” and other parts. A couple of Radial Firefly Tube Direct Boxes send all her bass signals to FOH.
Gather ’Round This Gibson
For this batch of shows under the Gather Round Sounds Tour umbrella, LSD revamped their catalog for stripped-down, alternative arrangements. This is how they described the tour on social media: “Join us for these easy going, semi-acoustic evenings full of the fan favs, some deep cuts, and maybe even some works in progress in our most relaxed, basement couch setting yet.” Accommodating those cozy cabin vibes, guitarist James Cornelison brought along this 2010s Gibson J-35 reissue.
Cowboy Chords
When the band reaches maximum campfire camaraderie, they perform as a guitar trio. In that arrangement, drummer/percussionist Mike Calabrase uses this Gibson Songwriter Standard EC Rosewood acoustic-electric.
This late-’60s Harmony H165 is singing better than ever, thanks to the facelift handed out by Old Style Guitar Shop in L.A. Aside from bracing upgrades and a proper setup, it’s been given two pickups (a piezo) and what looks like (but is unconfirmed) a variation of Seymour Duncan’s Hot Rails. When asked during the Rundown, James was unsure but did note that Old Style uses this pickup on all their acoustic overhauls. You’ll also notice a rubber bridge giving this storyteller even more vibe.
Roommate Robbery
Cornelison’s roommate received this Excel SS from D’Angelico, but James gravitated more towards the instrument, so it unofficially became his. (What a friend!) Since adopting the 6-string, he’s designated it as his “Frankenstein project” as he’s tried several experiments on it—using flatwounds, playing in open tunings, and replacing the stock neck humbucker with an old Teisco gold-foil pickup. It currently is the slide guitar for LSD material and stays in high-tension F-tuning for “Hush Money” off 2021’s Obviously.
We’re Not Worthy!
Single-coil sweetness is provided by this ’90s Squier Wayne’s WorldStratocaster. (As you would assume, “Stairway” is not allowed on this Strat—denied!)
Big Ups to Big Thief
“I’m a big fan of Adrianne Lenker and I always enjoyed that she played semi-hollow guitars with P-90s in it. I thought it was cool to have the reversal of the hollowbody archetype with P-90s instead of humbuckers,” admits Cornelison. This D’Angelico Deluxe DC features a set of Seymour Duncan STK-P1 Stacked P-90s and is serial #3.
Grandfathered Gibson
Original guitarist and cofounding member Mike “McDuck” Olson left this ’50s Les Paul Standard (finished in Heritage Cherry Sunburst) for Cornelison to use in his absence. James remarks that this electric does the bulk of the work when the full band is represented.
Twinkly Twilighter
On this subdued set, Cornelison plugged all his electrics into the above Magnatone Twilighter 112 combo.
James Cornelison's Pedalboard
This dialed-in setup was designed and built by longtime Jason Isbell tech Michael Bethancourt. Cornelison has onstage control of everything via the RJM Mastermind GT. Also, out front is a Boss TU-3 Chromatic Tuner and an Ernie Ball VP Jr volume pedal. His two-drawer rack holds the following pedals: a Source Audio EQ2 Programmable Equalizer, a JHS SuperBolt V2, a Behringer US600 Ultra Shifter/Harmonist, a JHS Colour Box V2, a Keeley Katana Clean Boost, JHS Morning Glory, and a Strymon Flint & Deco. Everything is powered by a pair of Strymon Zuma units. Additionally, an RJM Mini Effect Gizmo MIDI controller helps organize the signal paths.
