Does Weight Relief Ruin a Gibson Les Paul's Tone?

Short version: no, weight relief does not "ruin" a Les Paul, and if you've been talked out of a great guitar because someone online told you the holes killed its tone, you were given bad advice. The longer version is more interesting, because there are really four different things people are lumping together under the phrase "weight relief," and only one of them reliably changes how the guitar sounds and feels. I've had a lot of these on the bench, and once you know what you're actually looking at, the whole debate gets a lot calmer.

Here's the thing that trips people up: you cannot see any of it from the outside. Two Les Pauls can sit side by side, look identical, weigh two pounds apart, and have completely different guts. So let's open them up.

Illustration: the four kinds of weight relief you'll run into on a used Les Paul, viewed from the top before the maple cap goes on. Not to exact factory scale.

The four kinds of weight relief

Solid (no weight relief)

A one-piece slab of mahogany with nothing routed out except the control and pickup cavities. This is how the famous 1950s Les Pauls were built, and it's what a lot of "solid body purists" want. It's also the heaviest option - a genuinely solid Standard can land anywhere from about 9.5 to 11 pounds, and occasionally more. That heft is part of the appeal for some players and a dealbreaker for others whose shoulders have opinions.

Traditional 9-hole ("Swiss cheese")

Starting in the early 1980s, Gibson began drilling a pattern of nine round holes into the mahogany before gluing on the maple top. Because the routed body looks like a slice of Swiss cheese, that's the nickname it earned. This is a modest amount of wood removed - it takes the edge off the weight, usually landing a guitar in the 9 to 10 pound range, without turning it into a hollow instrument. Most USA Les Pauls carried this style from the '80s up into the mid-to-late 2000s.

Chambered

This is the one that actually changes things. Beginning in autumn 2006 and running until spring 2012, Gibson used large open chambers routed around the central wiring channel. Les Paul Standards from roughly 2008 to 2012 are the poster children here. Chambering removes a lot of wood - these guitars often come in at 7.5 to 8.5 pounds, which is remarkably light for a Les Paul - and it gives the body an airier, more resonant character that some players describe as almost semi-acoustic. This is the version where "it sounds different" is a fair statement, not a myth.

Modern / Ultra-Modern weight relief

From 2012 onward, Gibson moved to smaller elliptical pockets - "Modern" and later "Ultra-Modern" weight relief. Think of it as a compromise between the 9-hole and the full chambering: it pulls the weight down to roughly the 8 to 9 pound range without opening the body up enough to behave like a hollowbody. Most current-production Les Pauls use some version of this.

So does it actually change the tone?

Here's my honest take after handling a pile of them, and it lines up with what most experienced techs and a lot of forum veterans will tell you if you press them past the slogans.

9-hole vs. solid: basically inaudible. In a blind test, almost nobody can reliably pick the drilled body from the slab. The pickups, the setup, the strings, and your amp are all doing far more to your tone than nine small holes buried under a maple cap. If a seller marks a 9-hole guitar down as "compromised," that's a discount in your favor, not a defect.

Full chambering: yes, you can hear and feel it. The 2008-era chambered Standards are the genuine exception. Lighter, livelier, a touch less low-end thickness, and more prone to feedback at high gain. Plenty of players love that - it's a fantastic classic-rock and blues weight and vibe. Others miss the density of a heavier build. Neither camp is wrong; they just want different guitars.

Modern/Ultra-Modern: hard to pin down. Most people can't confidently separate these from a 9-hole guitar by ear. The bigger real-world difference is on your back after a three-hour gig.

A word of warning about names

Do not assume the model name tells you the construction. The plain Traditional was Gibson's answer for players who wanted no chambering - but depending on the exact year it was either 9-hole or fully solid (several 2013-2015 and later runs were solid, non-relieved). Meanwhile the Traditional Pro and Traditional Pro II actually used the 9-hole relief, which is a little ironic given the name. The lesson: the year and the specific guitar matter more than the badge on the headstock. When in doubt, weigh it and ask the seller directly.

What I'd actually tell a buyer

Buy the guitar that feels and sounds right in your hands, and let the weight-relief label be a footnote. If you're the kind of player who wants that dense, hard-hitting slab tone and you don't mind the heft, look for solid or 9-hole builds and expect a heavier instrument. If your back is the deciding factor, a chambered or modern-relief Les Paul will treat you a lot better on a long night, and the chambered ones have a genuinely lovely resonant character as a bonus. There's no wrong answer here - there's only the guitar that suits you.

If you want to feel the difference for yourself, it's worth trying a few side by side. We usually have a rotating mix of eras and constructions in the guitars in stock - everything from non-relieved-era Traditionals to lighter modern builds - so you can compare weights and voices without taking anyone's word for it, including mine.

FAQ

How can I tell what weight relief my Les Paul has?

You usually can't see it, so start with the year and model, then weigh the guitar. A Standard that's 7.5 to 8.5 pounds from 2008-2012 is almost certainly chambered; a 9.5-pound-plus guitar is likely solid or 9-hole. When it matters, ask the seller - a good shop will know.

Is a chambered Les Paul worth less money?

Not inherently. Some players specifically seek out the light, resonant 2008-2012 chambered Standards. Value comes down to condition, originality, and demand for that particular model - not the presence of chambers.

Does weight relief cause feedback?

Full chambering can make a Les Paul a little more feedback-prone at high gain and volume, similar to a semi-hollow. The 9-hole and modern elliptical styles remove far less wood and don't meaningfully change feedback behavior.

Which weight relief has the "best" tone?

There isn't one. Solid and 9-hole lean denser and thicker, chambered leans lighter and more open, and modern relief sits in between. It's a preference, not a ranking.
