Wampler Mofetta
wamplerpedals.com
Wampler’s new Mofetta is a riff on Ibanez’s MT10 Mostortion, a long-ago discontinued pedal that’s now an in-demand cult classic. If you look at online listings for the MT10, you’ll see that asking prices have climbed up to $1k in extreme cases.
It would have been easy for Wampler to simply make a Mostortion clone and call it a day, but they added some unique twists to the Mofetta pedal. While the original Mostortion had a MOSFET-based op amp, it actually used clipping diodes to create its overdrive. The Mofetta is a fairly accurate replica and includes that circuitry, but also has a toggle switch for texture, which lets you choose between the original-style diode-based clipping in the down position and multi-cascaded MOSFET gain stages in the up position.
Luscious Low Gain and Meaty Mid-Gain
The Mofetta’s control panel is very straightforward and conventional with knobs for bass, mids, treble, level, and gain. The original Mostortion was revered for its low-gain tone and is now popular among Nashville session guitarists. Wampler’s tribute captures that edge-of-breakup vibe perfectly. I enjoyed using the pedal with the gain on the lower side, around 9 o’clock, where I heard and felt slight compression that gave single notes a smooth and silky feel. I particularly enjoyed the tone-thickening the Mofetta lent to my Ernie Ball Music Man Axis Sport’s split-coil sound as I played pop melodies and rootsy, triadic rhythm guitar figures. The Mofetta has expansive headroom, and as a result there’s a lot of space in which you can find really bold, cutting tones without muddying the waters too much. Even turning the gain all the way off yields a pleasing volume bump that would work well in a clean boost setting.
There’s a lot of space in which you can find really bold, cutting tones without muddying the waters too much.
Switching the texture switch up engages the MOSFET section, introducing cascading gain stages that elevate the heat and add flavor the original Mostortion didn’t really offer. Classic rock and early metal are readily available via the MOSFET setting. If you need to stretch out to modern metal sounds, the Mofetta probably isn’t the pedal for you. Again, the original Mostortion was, first and foremost, a low-to-mid-gain affair, so unless you’re using it as a boost with a high-gain amp, the Mofetta is not really a vehicle for extreme sounds.
One of the Mofetta’s real treats is its responsiveness. Even at higher gain settings the Mofetta is very touch sensitive. You can tap into a wide range of dynamic shading just by varying the strength of your pick attack. I enjoyed playing fast, ascending scalar passages, picking with a medium attack then really slamming it hard when I hit a high climactic note, to get the guitar to really scream.
The Verdict
Wampler is a reliably great builder who creates pedals with a purpose. I own two of his pedals, the Dual Fusion and the Pinnacle, and both are really exceptional units. The Mofetta captures the essence of the Mostortion and makes it available at an accessible price. But even if you’ve never heard or played an original Mostortion, you’ll appreciate the truly versatile EQ, touch sensitivity, and the bonus texture switch, which expands the Mofetta’s range into more aggressive spaces. The wealth of dirt boxes on the market today can make a player jaded. But Wampler pushed into a relatively unique, satisfying, and interesting place with the Mofetta.

Electro-Harmonix Big Muff Pi Hardware Plug-in Effects Pedal and 2-in/2-out USB Interface
The Big Muff Pi® Hardware Plugin® is a new type of product that transcends the limitations of traditional DAW plugins to bring the unique qualities of analog sound to digital recording.
Analog hardware has a magical warmth that is beloved for its sound and feel. That was the genesis behind this product. Take the world’s most beloved harmonic distortion / sustainer and transform it into a plugin.
It works like a standard DAW plugin, but recorded tracks go through the actual analog circuitry of EHX’s Big Muff Pi, injecting analog warmth into your session. Of course, it integrates seamlessly with all the most popular DAWs like Pro Tools®, Ableton Live®, Cubase®, GarageBand®, Logic Pro X®, Reaper® and more.
Simply connect the Big Muff to your DAW by USB, select a track, and open the plug-in window. Instead of software emulation, you have real clipping diodes, overdriving transistors, and nature itself coloring your sound. The analog circuit is pushed over the edge and loses control. The sound you hear is the natural warmth of electromagnetic chaos.
The new Big Muff Pi Hardware Plugin can even function as a 2-in/2-out USB audio recording interface, which enables the user to record with or without the Big Muff effect engaged.
The Big Muff Pi Hardware Plugin can be used as a stand-alone pedal and shares the circuit design of the legendary 1973 Violet Ram’s Head Big Muff. That coveted pedal has set the standard for musical distortion and has been heard on countless classic recordings. It’s renowned for its unmistakable articulation and exceptional sustain, and now it’s has been updated to be true stereo. It also features Tone Wicker, Tone Bypass and presets. With the ability to store up to ten footswitch-accessible presets on the pedal itself and as many as your computer can hold, it is truly a Big Muff Pi like no other!
Vintage Fenders are some of the best-sounding amplifiers around, but from time to time, they need a bit of love to give up the goods. Here are the top issues you’ll encounter with your black- and silver-panel Fender amps, and how to fix them.
Trouble and worrying are part of a vintage tube amp owner’s life. In this article, I will try to teach some basic troubleshooting for vintage Fender amps. It will only require a little practice, patience, and, most importantly, curiosity, which to me is the single most important skill in life—we can accomplish great things by reading, seeking advice, trying, failing, and not giving up. So, let’s start!
As usual, I will refer to the silver- and black-panel Fender amps, but everything is applicable to earlier amps as well. I will often refer to tubes: On a Deluxe Reverb, for example, the tubes are referred to from V1 to V9. Always consult your amplifier’s schematic to confirm these placements.
No Reverb
The reverb tank is the most delicate component of these amps. The springs, wires, and soldering joints are thin and weak, and the reverb cables and plugs are also easily damaged, as they are exposed on the backside of the chassis.
First, check the plugs on both the amp and reverb tank. Unplug and switch the input and output to see if the previous player made a mistake. Often, the plugs are damaged and not conducting current, or the inner wire or outer insulation are broken. I recommend replacing old cables with new, vintage-correct ones if you suspect the slightest cable or plug issue.
“Trouble and worrying are part of a vintage-tube-amp owner’s life.”
A bad V3 or V4 preamp tube may also cause reverb loss. If replacing tubes or reverb cables does not help, you should try hooking up another amp’s reverb tank to verify whether you have an amp or reverb tank issue. The reverb springs may also have jumped out of position and need to be re-attached. I recommend refreshing soldering joints here.
No Vibrato
First, the footswitch must be plugged in for the vibrato to work. If you don’t have one or suspect that it’s malfunctioning, you can either buy or make yourself an “always-on” phono plug that is shorted internally with solder. A bad vibrato-driver tube may also cause vibrato loss, which is fixed easily by replacing the V5 with another 12AX7. If none of this helps, a tech should open the amp and inspect the vibrato tube circuitry, and/or replace the opto-oscillator component.
Blown Fuse
Pull all the tubes before replacing a blown fuse. If the fuse blows repeatedly without any tubes installed, a tech should be involved for inspecting the filter caps/resistors, power transformer, and the high-wattage resistors on the power-tube socket pins.
If the pilot lamp light is on when all tubes are pulled out, start inserting tubes one by one from the V1 rectifier tube. Turn power/standby on. If the fuse blows, the rectifier tube is bad. Then, insert both power tubes and turn power/standby on. If the fuse blows, you need new power tubes, and possibly new screen and plate resistors. Continue this procedure for each of the preamp tubes until you identify corrupted tubes that draw too much current.
Weak Tone
Check speaker cable(s) and speaker terminals. I find it useful to connect to a second amp’s speakers to determine if it’s the speakers or an amp that is the problem. (Remember to turn off or set the amp in standby whenever speakers are disconnected.)
Then, verify that the tubes are working by following the previous “blown fuse” procedure. Look for loose power-tube sockets causing bad connections by gently pushing them around in the socket. If speakers, tubes, and sockets are working fine, a tech should further inspect the amp.
Distortion, Reduced Volume, or Weak Bass
When playing powerful 40-watt amps at low volume, it can be difficult to hear if only one tube is working. If one of the power tubes is malfunctioning, you will experience distortion and farty bass. Non-matching power tubes can also result in distortion and reduced clean headroom, which is detected by measuring with a bias meter.
Preamp tubes in wrong positions may also affect volume response and cause an amp to distort too early or too late. Check all tubes and replace them one by one with fresh ones as you listen for tone changes. Sometimes we prefer the wrong tubes because we like more distortion. (My tube strategy is to replace tubes only when they fail entirely. I don’t mind weaker power, rectifier, or phase-inverter tubes since these amps are more than loud enough.)
Rattling Noise
Loose screws and nuts can cause rattling noise and should be inspected and tightened regularly, including on the chassis, baffle board, tilt-back legs, speaker, handle, and anywhere else. If the baffle board is warped and worn so that the screws are not tight, I never hesitate to install a new, solid-pine baffle. This usually improves tone and robustness compared to old, warped MDF baffles
A chance glance at a Stefan Grossman LP led our columnist to discover the acoustic connections between the U.S. and Japan.
When acoustic guitarists like myself hear an album that just sounds so good, we might fuss less about gear and home in more on performance and atmosphere. Indeed, those were the things that blew me away on country-blues guru Stefan Grossman’s album from the late ’70s, Acoustic Guitar. Dynamic playing with a healthy big-room sound, the production was a far cry from a lot of Grossman’s late-’60s output, some of which was recorded in closets on budget reel-to-reel decks.
The back cover of this particular LP offers some important clues, including one that turned out to be the jumping-off point for this column: Acoustic Guitar appeared on Japanese EMI subsidiary East World, and was recorded at the EMI studios in Toshiba, Japan, by an entirely Japanese crew. Stefan reveals some more details to help me understand why I found the sound of this record so striking:
“At EMI at the time, the big thing for audiophiles was direct-to-disc recording, which is funny, because that’s the way that all the old records from the 1920s were recorded. You would have to do a non-stop performance, while the masters were cut in real time. It was like a concert. Play a song, wait 3-5 seconds before playing the next song. You couldn’t stop. You would do two sets right through, one for each side. Then you would do it twice more, because the masters for direct-to-disc were then only good for a certain number of copies. If the label sold out of the first pressing, they couldn’t go back to the first master, they would go to the second, then the third. So, each set was ever so slightly different: the same music, but different changes and licks.”
I’ve discovered that in the world of fingerpicking acoustic guitar, there has been a long and fruitful exchange of ideas and experiences between players from the U.S. and Japan. I spoke to several amazing guitarists from these countries, and one name that came up often was Tokio Uchida.
As it happens, Uchida got turned on to fingerstyle guitar when he read about Grossman during one of Grossman’s earliest tours of Japan in the late ’70s. Uchida became a student of Grossman through correspondence and study, visiting the U.S. for the first time in 1987. Uchida’s playing impressed Grossman, and he appeared on stage with his hero at a concert in California. The two became fast friends. Uchida later appeared at a festival marking Robert Johnson’s 100th birthday in Greenwood, Mississippi, and recorded a duet album with Grossman. Back in Japan, Uchida has followed in the footsteps of his mentor, writing his own original music and also starting the TAB Guitar School, which offers instructional materials for acoustic styles. Uchida has also promoted concerts and tours for many fingerpicking heavyweights, including Duck Baker, Ernie Hawkins, Pat Donahue, and Woody Mann.
“Every single venue owner that I’ve worked with over there knows how to run sound. They’re listening rooms, and everything works!”
One of the players that Uchida brought to Japan for their first visit was Minneapolis ragtime guitar legend Dakota Dave Hull. Hull has since toured Japan multiple times, and just this year did a five-week, 33-date run that resulted in his new CD, Live in Japan. Hull offers some insights on differences between the American and Japanese acoustic scenes: “A lot of the venues are tiny. It’s pretty insular, not a lot of crossover between old time, bluegrass, blues, trad jazz. We end up playing in small rooms; some might be as small as a dozen people! But these rooms are built around the idea of live music; the stage and the sound system went in first. Every single venue owner that I’ve worked with over there knows how to run sound. They’re listening rooms, and everything works!”
During an early tour of Japan, Hull was paired on bills with a humble ragtime guitar wizard named Takasi Hamada, and the two hit it off in a big way, collaborating on all of Hull’s Japanese excursions ever since. Hamada is, in my opinion, one of the finest ever purveyors of ragtime on the acoustic guitar. His playing is very sophisticated, but never sounds dusty or academic. It has a joyous bounce, and he makes turning 88 piano keys into 6 strings seem almost easy!
Hamada’s signature sound is a combination of his amazing arranging and playing ability, but also a tuning that he devised himself. “I really wanted to arrange Tom Shea’s piano piece ‘Little Wabash Special’ for guitar, so I devised an irregular tuning based on C as C–Ab–C–F–C–Eb,” Hamada explains. “In 1995, I changed the 6th string to Eb so that I could play beautiful alternating bass: Eb–Ab–C–F–C–Eb. It seemed to suit me, and I later named it ‘Otarunay Tuning’ after the Ainu name of my hometown, Otaru.” Since to this day ragtime is predominantly played and taught on piano, its a testament to Hamada’s mastery of the form that he was one of the only guitar players invited to appear at the 2023 Scott Joplin International Ragtime Festival in Sedalia, Missouri.

Born outside of Charlotte and raised in Asheville, Combs is a proud North Carolinian. Growing up singing at school, it wasn’t until he attended Boone’s Appalachian State University that Combs first performed his own songs at a beloved local bar, leading him to his now historic country music career. Since moving to Nashville in 2014, Combs continually returns to North Carolina for landmark moments including his first-ever headline stadium show at Appalachian State’s Kidd Brewer Stadium in 2021 as well as sold-out, back-to-back nights at Charlotte’s Bank of America Stadium last summer.
Church, a native of Granite Falls, also began his musical journey in Western North Carolina, playing gigs locally throughout high school and into his time at Appalachian State University before chasing his dream to Nashville. He continues to split time between Tennessee and North Carolina with his family, even returning to the Appalachian Mountains to record his most recent project, the three-part Heart & Soul, in Banner Elk. In 2016, he was inducted into the North Carolina Music Hall of Fame and in 2022, he was awarded the North Carolina Award, the state’s highest civilian honor. Most recently, he released the song “Darkest Hour” in response to the recent devastation, with all publishing royalties being donated.
Although he is a Michigan native, Strings’ life and career has been deeply impacted by the state of North Carolina both personally and professionally, as it is home to some of his most passionate and supportive fans. Over the past few years, Strings has performed at major venues across the state including an upcoming six-night run at Asheville’s ExploreAsheville.com Arena this winter.
Singer-songwriter Taylor moved to Chapel Hill, North Carolina with his family when he was just three years old. Taylor’s father served as the Dean of the University of North Carolina at Chapel Hill Medical School from 1964 to 1971. Taylor’s childhood home was on Morgan Creek Road in Chapel Hill-Carrboro. In April 2003, a bridge over Morgan Creek was dedicated to the musician and renamed the James Taylor Bridge. Taylor’s childhood experiences in North Carolina influenced many of his most popular songs including “Copperline” as well as the beloved “Carolina in My Mind.” As a recording and touring artist, Taylor has touched people with his warm baritone voice and distinctive style of guitar-playing for more than 50 years. Over the course of his celebrated career, he has sold more than 100 million albums, has won multiple Grammy Awards and has been inducted into the Rock and Roll Hall of Fame, the Songwriters Hall of Fame, as well as the North Carolina Music Hall of Fame in 2009.
