This convenient, easy-to-use controller can open up an entire world of sonic shape-shifting. Here are some tips to either inspire you to try one or expand how you’re currently using this flexible, creative device.
If you’re not yet using expression pedals, you should consider them. They have the power to expand and control your sonic universe. For the uninitiated, expression pedals are controllers that typically look like volume or wah pedals. Of course, traditional volume and wah pedals are expression pedals, too, but they are dedicated to controlling only those two effects.
Modern expression pedals allow you to assign and control parameters of your stomps or modelers by moving the expression pedal as you would a volume or wah. Dunlop, Boss, Ernie Ball, Yamaha, Behringer, Mission Engineering, and other manufacturers make these handy devices.
Many, but not all, of today’s stompboxes and modelers have expression pedal inputs that allow for manipulation of one or more parameters of those devices. In the past, this required bending over and turning a knob, or trying to turn a small knob with your foot—both of which can hamper your playing. The freedom of an expression pedal is the control you have over more aspects of your sound, especially in a live setting.
Although some of the uses for expression pedals below can also be accomplished by creating multiple presets, that will not allow real-time control over the parameters like an expression pedal will. Here are some notes about expression pedal use that might get you thinking about how one could help you.
Delay Repeats: Controlling the timing of a delay with tap tempo is very common, but how about controlling the number of repeats? With an expression pedal, by setting the expression control on your delay to control the number of repeats, you can easily go from a few for your rhythm sound to more for your lead sound, and then back off again.
Reverb and Delay Mix: The mix control on reverb and delay pedals allows you to balance the amount of wet to dry signal that you hear. There is often a delicate line to having just the right amount of wet signal with these two effects. If you have too much, your sound can be washed out and undefined. Too little and it can be dry and lack space. The part you are playing, and the venue you are in, can also change the amount of mix you need for these effects. By using an expression pedal for the mix control on reverb or delay, you can alter the sound on the fly to compensate for the part and the room, including turning down the mix for busy parts and up for parts with fewer notes.“Some uses for expression pedals can also be accomplished by creating multiple presets, but that will not allow real-time control over the parameters like an expression pedal will.”
Modulation Depth: The depth of a modulation effect, like a phaser, can drastically alter your guitar sound. A light amount can create a feeling of subtle movement, while a heavy amount can give a thick, underwater-type sound. An expression pedal can help you create a constant feeling of change throughout a song, allowing you to build up and break down the depth for different sections as you see fit.
Tremolo Speed: While the speed of tremolo can often be controlled by tap tempo, using an expression pedal for the same parameter offers other creative uses of the effect. With an expression pedal, you can easily speed the tremolo up to make subtle increases to the energy of a part or slow it down to decrease the energy. You can also create drastic changes in the speed that sound like a fan accelerating or slowing down. Or you can abruptly turn the tremolo off. This last option can be an exciting way to end a song or part.
EQ Change: Every guitar player uses EQ to sculpt their sound—whether via the tone controls on your instrument or amp (modelers included), or a dedicated equalizer used as part of your rig. Subtle tweaks can help you do things like balance out different guitars, cut through the mix more, or compensate for a boomy stage. Real-time control of EQ with an expression pedal is more common in the modeler world than the amp and pedal world, but it does exist in both. For example, increasing the midrange can give you more clarity and cut for solos. Decreasing it can create a flatter sound that can help you stay in the mix with the rest of the band. An expression pedal allows you to have one setting and alter it for multiple situations or guitars as opposed to having separate presets.
While this is a very short list of options for expression-pedal use, it should give you a good place to start. The most important thing is to always be creative, have fun, and find your own voice. An expression pedal can help you do all three.
This amp with tone and headroom to spare proves that sometimes the best gear isn’t the most expensive or admired.
I’ve been wanting to tell you about the beautiful 1966 Twin Reverb I owned for 30 years. It was a find. I bought it for about $400, including a flight case, in the late ’80s, when I started to play in clubs and felt the need for more volume and headroom. I knew it was old, but had no idea that it was a ’66 until I brought it to the shop to have the pots replaced, caps tested, and a general check-up.
Until then, I had never heard of Fender’s “transitional era,” the time from roughly late 1964 to early 1966 when Fender Musical Instruments’ ownership passed from Leo Fender to CBS. “Too bad it’s not a ’65,” several other players told me when I shared the story of my acquisition. “In ’65, Fender made really great Twins. The CBS stuff is hit-or-miss.” As far as I was concerned, my Twin was a hit. It could punch through my band’s wall of sound and took to pedals wonderfully, yielding all kinds of gnarly noises with a Tube Screamer and a RAT, and creating open, spectral spaces with a DigiTech PDS 1000 delay and Boss CE-2 Chorus. Eventually I paired it with a 50-watt Marshall Super Lead and a channel switcher, so I could have the best of both classic-tone worlds. (Yes, I threw my back out a lot in the ’90s.)
I’m good at ignoring gear snobs, but given how great this Twin was for recording and gigs, I was puzzled by its second-class status. It was only after an onstage mishap that I learned there was more to this amp than my cork-sniffing friends knew. One night, mid-gig, my Twin simply went silent. I learned that the output transformer had blown. Bad caps? An overload? I dunno. But when I took it to my local amp resurrectionist, he started probing around inside and informed me that my Twin was essentially a ’65 in ’66 clothing—right down to the Fender Musical Instruments lettering on its black panel. All the components—including the factory-installed JBL D120F speakers—were the same as he’d seen in most ’65s he’d worked on, and he told me that during the transitional era, many of Fender’s products were made exactly as they’d always been. It was only after the CBS ownership was firmly established that the company shifted to a more cost-conscious style of mass production, with resulting compromises in quality. (In 1985, Fender employees bought the company and restored its reputation.) I felt like I’d lucked out a second time.
At 85 watts and two channels, any Twin is a monster tube amp, and it’s hard to imagine just how loud and clean one can get unless you’ve opened a Twin up all the way. (I only did that once, just to see what it could do, and regretted the ringing it left in my ears for days.) With tremolo and the reverb that defined what the word means in a Fender, the Twin is the sound you’ve heard and loved on myriad classic rock, jazz, blues, and R&B records. I confess that I’m no longer sure what replacement transformer my amp tech installed, but the sound remained the same.
Like it says, “Fender Musical Instruments.”
Since I’ve always had a player’s, rather than a collector’s, mentality, eventually I did alter the amp to fit my shifting tastes. I needed to replace the caps at some point, and when a speaker burned out, I put Celestions in both slots—a 30- and a 35-watt, because mixed-wattage speakers were kind of a trend at the time, so I figured I’d try it. The amp still had an absurd amount of headroom, but just a little grit, which is what I was looking for. I last used it for recording an early ’70s psychedelic-rock tone for an album I was working on in 2017, and just before the pandemic I sold it for $1,500. In the case, it came close to 90 pounds, and I just didn’t want to cart it around anymore. If it was a mint ’65, the asking price would have been around $5,000, but I felt I'd gotten more than my money’s worth.
“I’m good at ignoring gear snobs, but given how great this Twin was for recording and gigs, I was puzzled by its second-class status.”
The moral to this yarn is simple: Don’t turn your nose up at gear that doesn’t fit a trope, because you might be pleasantly surprised. Also, if it sounds great and does the job for you, what else really matters? It’s good stuff! Now, are you ready for the story of the ’68 factory-painted cherry sunburst Les Paul Standard I picked up for $650?
The durable but often maligned overdrive has thrived for more than 30 years. And not just on shredders’ pedalboards. Here’s why.
With over a million produced, the MT-2 Metal Zone is Boss’s second-most-popular overdrive ever—a significant accomplishment, considering Boss pedals have been ubiquitous for decades. I’ve got two Metal Zones. But, much like the late Rodney Dangerfield, the Metal Zone often “don’t get no respect.”
My first Metal Zone was simply abandoned at a guitar camp I taught at. Despite efforts to find its owner, it was never reclaimed. The second one was part of a package deal where the seller must have been getting rid of what he considered his undesirables: a Boss BF-2 with a faulty power-supply jack that only works with batteries, a Boss BCB-60 pedalboard with foam that stinks and is filled with irremovable allergens or something that always makes me itchy, and a perfect-condition Metal Zone—all for a mere 35 bucks.
But somehow, over the decades, the Metal Zone got a bad rap. The endless hordes of preteens that butchered “Crazy Train” through a Metal Zone at their local Guitar Center probably didn’t help. Even with a new Waza Craft edition in Boss’s lineup, things haven’t changed much. If you read an internet discussion of the Metal Zone, you’re guaranteed to find someone boldly commenting that it sounds like “buzzing bees.”
Likewise, if you search “Boss Metal Zone” on YouTube, the first thing that comes up is Ola Englund’s “Boss Metal Zone—Worst Distortion Pedal Ever?” video, which currently has over 3.5 million views. You’ll also see “What’s the Worst Pedal Ever? Boss Metal Zone Pedal, Demo” by Marty Schwartz, a famed YouTuber with over four million subscribers. And there are many more videos along the same lines. But if you dig deeper, you’ll find that despite those derisive, clickbait titles, many Metal Zone videos actually praise the little demon. And with good reason!“What immediately grabs my attention is its ridiculous sustain; for soloing, the pedal makes legato licks feel fluid and easy to play.”
When the Metal Zone first came out in 1991, it was literally the hottest piece of gear in the guitar world. It was the undisputed star of a stompbox shootout of 29 pedals in the October 1992 Guitar Player. The magazine’s editors proclaimed: “We knew the Metal Zone was a hot item when we couldn’t keep our test sample long enough to photograph it. The store we borrowed it from had sold it and was back-ordered 50 units.” The story was followed by comments like, “This thing starts off where others leave off,” “Mind-blowing. Never heard so much bass,” “Definitely a must-have,” and “Totally sick!” The shootout concluded with “The Boss Metal Zone easily grabbed top metal honors. Its absolutely fierce sounds make the $139.50 price tag [editor’s note: list price] seem like a deal.”
If you’ve used one before, you’ll likely agree—this silicon-driven, two-stage-clipping circuit is a really badass pedal! What immediately grabs my attention is its ridiculous sustain; for soloing, the pedal makes legato licks feel fluid and easy to play. For sharp and percussive metal rhythms, the Metal Zone also kills. With its massive bottom end, it has given me heavier sounds than I’ve gotten with more expensive pedals or high-gain amps.
The Metal Zone has more tone-shaping options than many other dirt pedals. There are six controls crammed into the space of four. In addition to the level and distortion knobs, the EQ dials are dual-function concentric—high and low, and mid freq and middle, which boosts or cuts the frequency you have the mid freq set to. Some players enjoy using the Metal Zone as a preamp, straight into the effects loop. Others put it between the guitar and amp. However you fire it up, if you invest time into fine-tuning the settings for your needs, you’ll be greatly rewarded.
If you’re a hard-rock or metal player, the Metal Zone is a no-brainer. Pro players like Biffy Clyro’s Simon Neil and Megadeth’s Dave Mustaine have used the Metal Zone. But it’s also surprisingly versatile—even Prince used one! Despite its name, it can convincingly get into mid-gain overdrive territory, and with the distortion knob around 9 o’clock, it’s pretty touch sensitive.
At only $99 new—$50 more for the Waza version—and, if you’re lucky, maybe $20 or so used, the Metal Zone is incredibly undervalued. I wouldn’t be surprised if the Metal Zone makes its way back to the top of the pedal pyramid some day. Guitar players are notoriously fickle and tend to be very impressionable. It just takes something as simple as one artist association and the tide can turn for any piece of gear. The Marshall ShredMaster became a cult classic simply because it was used by Jonny Greenwood of Radiohead. Maybe if John Mayer uses a Metal Zone the next time he covers “Panama,” it will again reign supreme.
