Dweezil Zappa takes us on a trip down eccentric memory lane with Frank Zappa’s iconic and modded Les Paul, mimicking a wah pedal on a knob. Sweetwater’s latest video is as if a mad scientist and a guitar had a punk fling—bizarre, daring, and brimming with feedback.

Frank Zappa’s Les Paul: Sweetwater’s Electric Playground with Dweezil
A Rock Legend’s Quirky Axe
Among the pantheon of rock gods, there’s one name synonymous with innovation and a dash of lunacy: Frank Zappa. Sweetwater’s video introduces us to the latter’s unorthodox weapon of choice, the Shut Up ‘n Play Yer Guitar Gibson Les Paul, presented by his very own lineage, Dweezil Zappa. This is no ordinary axe but a sonic playground heaving with as many tricks as a magician’s hat. Bought off the rack from Manny’s Music back in the late ’70s, it rapidly became Zappa’s main squeeze in the ’80s, carrying the weight of ambition with a hefty 15-pound build. But don’t let its weight fool you, under the hood, lies a hodgepodge of electronics, including a five-way rotary switch, EQ, and a preamp boost circuit—ensuring this Les Paul is anything but predictable.
The Technological Sorcery
Dive headfirst into the technological wizardry embedded in this guitar, and it’s a mad scientist’s laboratory on six strings. Dweezil, our eager guide, eagerly showcases the neck pickup sound, which defies Les Paul conventions with a peculiar high-end boost thanks to its internal boost circuit and EQ. But here’s the twist: imagine a wah pedal in the guise of a plain knob. “Park it wherever you fancy,” Dweezil notes, as he twists the knob, allowing the guitar to mimic a treble-rich wah wail. With each click of its five-way rotary switch, the guitar belts out myriad flavors akin to a dodgy kebab shop offering unpredictable tastes. The knobs extend the range from dark and brooding lows to searing, almost shrill highs that you wouldn’t think were birthed from a Les Paul. The guitar lurches from bright, succinct notes to the kind of low-end warmth that’s perfect for a slow, grinding punk rhythm.

"It's basically a wah pedal on a knob and you can park it wherever you want."
The Zappa Philosophy: Feedback and Chaos
In the realm of Zappa’s sonic ethos, the ability to garner feedback was king, a feedback junkie’s route to auditory nirvana. Dweezil explains how Frank Zappa set the stage aglow, adjusting on the fly to summon the right frequency for that sweet, uncontrollable sustain. The preamp, another cog in the machine, could be flicked on or off at will, adding layers of high-end that one wouldn’t expect from an ordinary Les Paul. Dweezil demonstrates the contrast by toggling the preamp circuit, revealing the guitar’s chameleon nature. Hitting notes that blossom into feral feedback, he echoes Frank’s philosophy of not knowing what’ll happen until it does. A Les Paul playing like it’s got a bit of Telecaster trapped inside, live performances with this guitar were as spontaneous as a punk gig crash.
Experimentation in Every Note

"I'm going to show you how my dad tried to dial in the amount of gain that he wanted."
You can almost see Frank Zappa’s grinning spirit whenever this guitar sings, bending notes to the edge and beyond. Dweezil talks us through the process of dialling in the gain, hunting for that golden string-icebreaker note, which dances on the edge of feedback. This guitar is not just an instrument; it’s a muse of experimental soundscapes. With a spin and a flick, what starts as a gentle hum can build to a screaming crescendo, brimming with the energy of a frenzied punk fan at their favourite band’s show. Zappa had no qualms about treating this guitar like a sonic chemistry set, dipping into the Frankenstein effect where every modification was another wild, scientific leap. Dweezil leaves us with a Zappa-style lick as a parting gift, a nod to a time when rhythms were deliberately askew and music was limitless. It’s clear the guitar retains Zappa’s mischievous spirit, coaxing players to dance between chaos and harmony.
Closing the Loop with a Lick
As we near the finale, Dweezil doesn’t just leave us with a history lesson; he sends us off with a signature Zappa lick, an oddball rhythm tied together with open strings. It’s as if to say, ‘Here’s the toolkit for chaos. Now crack on with it.’ This isn’t your basic scales like you’d practice in a dreary music lesson, instead, it’s an instruction on exploring the unknown, a nudge towards making music that’s as off-kilter as it is captivating. Sweetwater’s video ends not just with an invitation to explore their range but an urging to embrace the eccentricity in your gear and playing. After all, isn’t music best when it’s unexpected, taking the stage like a rowdy geezer at last orders?
