Can you control the tone, feel, and sag of your amp ... with a light bulb?
Whenever a piece of my electronic gear breaks, I have my guy Brett Clark fix it. Clark has 16 US patents to his name for fiber optics, electronics, LED (Light Emitting Diode), and speaker products. He also has a pedal company called Distopia that specializes in oddball and unique effects. Brett and I were having an āexperimentation dayā and decided to check out this old and tattered contraption that looked like an extension cord with a light bulb socket soldered into the middle of the cord. This device was supposed to act as a power attenuator, with the volume being dictated by the wattage rating of the bulb. Since the socket wasnāt working, Brett grabbed a lamp and rigged the zip cord into the lamp to replace the broken component on the original apparatus.
Not quite understanding the science behind how the device functioned, I asked Clark to explain. I learned that the light bulbās load is always changing due to the fluctuating temperature and brightness of the bulb. The bulb is in series with the speaker, so as the bulb absorbs power and its impedance increases, it decreases the amount of power that goes to the speaker. When a light bulb is cold, it only provides 1/10 to 1/15 the amount of resistance as it does when hot. On a 40-watt bulb, for instance, a light bulb measures 26 Ī© cold, but it will be over 300 Ī© when lit up correctly. Brett and I tried different bulbs with different wattage ratings and found that each bulb changed the tone, feel, and sag of the amp.
We began our experiment with an 11-watt bulb. It reminded me of the guitar tone on āWild Thingā from the Live at Winterland album by the Jimi Hendrix Experienceāit was very compressed and low volume. Using a 100-watt bulb with the 100-watt head was interesting because the volume was still lowered and compression was present in the tone once again. But the 100-watt bulb didnāt compress the attack like the 11-watt bulb didāit instead compressed only the bloom of the notes and added an unbelievable amount of sustain. Not only did the light bulb experiment provide interesting tones, it also entertained us with a bonus light show. The light bulbās brightness increased when I hit the strings with more force, but when I wasnāt playing, the bulb was completely dark.
Through the experimentation process, I remembered that my old Morley Tel-Ray wah used a light bulb to make the pedal function. A Tel-Ray wah uses a light bulb and an LDR (Light Dependent Resistor) to take the place of the potentiometer that youāll find in most modern wahs. A big advantage of the light bulb and the LDR is that you donāt have to deal with a pot getting scratchy and noisy over time. The disadvantage is that the light bulb burns out occasionally, so if you acquire one of these wahs, be sure to track down some extra bulbs for backup. A Tel-Ray wah has an enormous sweep and is great for handling frequencies from baritones, 6-string basses, and even keyboards. Musicians often use terms that relate to light, like dark and bright, to describe how certain tones sound, and this language is certainly appropriate when discussing the sounds of a Tel-Ray. Darker tones provided from the wah in the heel position means that the LDR is not receiving very much light, and brighter tones in the toe position means that the LDR is receiving a lot of light.
Iād be interested to see more companies investigate the tonal possibilities that can be achieved using light bulbs. Guitar players are always looking for the next new piece of gear and new ways to get great tones.
Brent Mason is, of course, on of the most recorded guitarists in history, who helped define the sound of most ā90s country superstars. So, whether you know it or not, youāve likely heard Masonās playing.
Professional transcriber Levi Clay has done the deepest of dives into Brent Masonās hotshot licks. At one point, he undertook the massive project of transcribing and sharing one of Masonās solos every day for 85 or so days. Mason is, of course, on of the most recorded guitarists in history, who helped define the sound of most ā90s country superstars. So, whether you know it or not, youāve likely heard Masonās playing. Levi shares the insight he gleaned from digging deep, and he tells us what it was like when they shared a stage last year. Plus, Levi plays us some great examples of Masonās playing.

AEROSMITH guitarist and songwriter JOE PERRY is set to return to the road for a series of August performances with THE JOE PERRY PROJECT. The 8-date run kicks off August 13 in Tampa, FL and wraps August 23 in Port Chester, New York, with an August 19 performance in PERRYās Boston hometown (see the itinerary below). For the North American trekāwhich marks the first solo shows for PERRY this yearāthe legendary guitarist will be joined by his Aerosmith bandmates Brad Whitford (guitar) and Buck Johnson (keys), along with The Black Crowesā Chris Robinson (vocals), and Stone Temple Pilotsā Robert DeLeo (bass), and Eric Kretz (drums).
āWellā¦itās time to let the music do the talkin again,ā PERRY says. āIām really excited about the JPP line up this year!!!! Most of these guys played with me at The Roxy in L.A. at the debut event for my latest solo album [Sweetzerland Manifesto] in January 2018. Theyāre all busy as hell but thankfully theyāre able to carve out some time for this run. And Iām not only lucky enough to have Brad Whitford onstage with me but Chris Robinson of The Black Crowes! [who sang āFortunate Oneā on Sweetzerland Manifesto MKII], Robert DeLeo and Eric Kretz from STP!!! and Buck Johnson who plays keys and sings with Aerosmith, the Hollywood Vampires, and is also a solo artist in his own right.ā
For the shows, the Rock and Roll Hall of Fame inductee says āthe set list is gonna include my fav JPP cuts, STP, Black Crowes, and with Brad weāll be hitting the Aero hits and some deep cuts and then ya never know!!!! Gonna be a BLAST, and if youāve ever been to one of my shows you know the words GARAGE BAND on STEROIDS come to mind! See you there!!!!ā

Seasonal changes are tough on your acoustic. Hereās how you can take better care of your prized instrument.
As you read this, spring is in bloom in most of the US, or maybe it has been for some time. Iām timing this column specifically to ask acoustic guitarists, in this season of increasing humidity and comfortable conditions, to prepare for whatās coming. Itās never too soon, and time flies. Before you know it, weāll be back to the maintenance phase and you might be blowing up the phones of your local guitar shops, luthiers, and techs. Iām here to encourage a decidedly old-school approach to preventative guitar maintenance, and yes, it starts now.
Why, you ask? Well, as the lead luthier at Acoustic Music Works, I can tell you that in my nearly 15 years in this position, this was the worst winter ever for preventable repairs on acoustic guitars. Fret sprout, bridge lifts, top sink, soundboard cracks, back cracks, loose binding, general malaise⦠These hit us very hard in the winter that spanned 2024 and 2025. Am I complaining? On the one hand, no. This is part of how we make our money. On the other hand, yes! Repair schedules related to dryness and humidity issues can stretch into weeks and even months, and nobody wants to be without their favorite instruments for that amount of time. With a little thoughtfulness, however, you might get through next winter (and every one thereafter) without hefty repair bills or time apart from your musical companion.
Our preparation is going to start with an unlikely but very important guitar accessory: the humble notebook. Plain, lined, grid, day planner⦠it doesnāt matter. We all need to actively participate in our instrument maintenance, and in my experience, fancy apps that track humidity via Bluetooth breed a kind of laziness, a feeling of safety that might prevent us from actually physically looking in on conditions. Better we keep an analog, well, log, so that we know where things stand, and I suggest checking in daily.
āThis was the worst winter ever for preventable repairs on acoustic guitars.ā
Track your relative humidity, both in the case and in the room where your instruments mostly reside, but also take notes on your action height, top deflection (StewMac has some great tips for measuring this) and anything related to playability that you believe you can observe empirically.
Dryness is the root cause of most guitar issues that manifest in the fall and winter months. Symptoms of dryness include sharp fret ends, falling action and dead frets, sunken top around the sound hole, and cracks and bridge lifts. With your trusty notebook, youāll get a feel for the sensitivity level of your instrument, and that knowledge is power!
A few other basic implements will not only assist you in your observations, but may also satisfy your need to buy guitar-related things (at least for a minute). Getting quick and comfortable with a fret rocker is a great skill to have, and is invaluable in diagnosing buzzes due to high frets or frets that have come unseated due to dryness. A well-calibrated relief gauge might seem luxurious, but it can prevent you from making unnecessary or extreme truss rod adjustments. A string action gauge, or even a simple machinistās rule or set of feeler gauges, will help you keep track of your action. Get a three-pack of hygrometers so you can average their readings, rather than depending on one.
Lest we forget: A guitar can not only be too dry, it can also be too wet. By beginning your maintenance diligence in the spring/summer, youāll also be able to tell if your instrument is the victim of a too-humid environment. The signs of over-humidification are subtle: Your action may rise from a puffed-up top, and in extreme cases, glue joints could begin to fail. In my experience, an over-humidified guitar will suffer from dulled tone, almost like a sock in the sound hole. If youāre sensing a lack of clarity in your guitar all of a sudden, start with new strings. If it persists, it might be due to over-humidification, and you may want to introduce a desiccant to the case for a time. The more lightly built your guitar is, the more sensitive it will be to seasonal changes.
By getting into these habits early, youāll be empowered by knowing your instrument more intimately. Youāll understand when and why changes in tone and playability might have occurred, and youāll hopefully save on repair bills year-round. Feel free to reach out with any questions. Who knows? I might just send you a notebook with an AMW sticker on the cover!
