Overdrive

Keeley’s Super Phat Mod has been around for a while now, but the Super Phat Mod Germanium takes the popular overdrive circuit to a whole new level. Germanium transistors inserted after the tone stack give the Super Phat Mod a tone powered by screaming hot tubes. You get a warm, classic overdrive that is extremely sensitive to your picking dynamics. You also get a choice between two voicings: go Flat for a level EQ or switch to Phat to give your signal a low-frequency boost.

The Red Dirt is the distillation of Keeley’s highly-prized Mod Plus and Baked TS09 mods, serving up classic overdrive with extreme sonic versatility. From mild dirt all the way to full-on tube-breaking overdrive, you get a highly dynamic and touch-sensitive tone. Its complement of tone-sculpting tools includes a dedicated Tone control for treble, Drive and Level knobs for gain and output, and a two-position mode switch that lets you choose between Hi and Lo gain modes.

The Super Phat Mod Full Range Overdrive pedal takes Keeleys’s popular Super Phat Mod overdrive circuit to the next level. An updated JFET gain circuit gives your signal a layer of transparent overdrive tone powered by screaming hot tubes. You get a warm, classic overdrive that is extremely sensitive to your guitar volume picking dynamics. You also get a choice between two voicings: go Flat for a level EQ or switch to Phat to give your signal a low-frequency boost.

Devised within the dark depths of Kirk Hammett’s brain, a legendary circuit has been tweaked to perfection and armed with five switches to allow you supreme control of your tone. The Ghoul Screamer by KHDK is a multipurpose device capable of drastically enhancing your sound palette. The incredible versatility of controls spans from a clear boost to intense overdrive. Besides the three standard controls (Volume, Drive, Tone), KHDK incorporated five tiny toggle switches offering enhancements for Body, Bass, Highs, and two variations of Compression.

Powered by KHDK’s proprietary circuit, the No.1 pedal is built on the spirit of an overdriven tube amp. Turn this device on, and you will feel like you have connected to a mighty distortion channel on a tube amp. The No.1 consists of Treble, Bass, Volume, and Gain knobs, as well as a Hi/Lo toggle. The Gain adjusts the circuit’s unity gain, while Volume controls the pedal’s overall output volume. Similar to other KHDK pedals, the No.1 is quality tested and manufactured in Kentucky, USA.

The Koogo Overdrive pedal carries Tone, Level, and Gain knobs. It allows you a choice between Warm and Hot modes. Select the Hot model if you want a more powerful full tone or Warm for a sweeter and smooth sound, making the tone performance more unique and dynamic. The Koogo Overdrive is made of high-quality zinc alloy. It is sturdy, durable, and compact, saving plenty of space on your pedalboard. It also features an LED indicator that displays the working state and true bypass for transparent tone.

The Big Fella guitar effects pedal is all about big rock sound. This is one of Lunastone’s “True Overdrive” pedals; instead of clipping diodes, its overdrive tone is powered by cascading gain stages. This translates to a tube-like, naturally compressed sound. You get two distinct switch-selectable overdrive flavors: OD1 goes up to low-gain crunch, while OD2 serves up a smooth distortion with more gain. There’s also a dedicated boost footswitch, so you can use the overdrive and the boost independently or together.

It won’t be able to push your amp much further than a low growl, but high-gain aggression is not what Lunastone’s Blue Drive 1is all about. This guitar effects pedal is the perfect low-gain distortion for giving your amp’s clean tone a more gritty bite without compromising your sound’s core tonal characteristics. It’s very transparent and has a sweet, lingering sustain that lets held notes decay naturally. Volume, Tone, and Dist knobs give you plenty of tone-shaping flexibility.

As a low-gain option for musicians who want the tone of True Overdrive 1 but don’t have much use for the higher gain stages, the Smooth Drive 1’s overdrive is subtle, smooth, and gentle. With a little persuasion, though, this guitar effects pedal from Lunastone can still give you a dirty, low-gain growl that’s perfect for blues and rock. And since the control knobs are placed diagonally, you can quickly adjust them with your foot even when you’re in the middle of a solo.

The “Brown Sound” blew minds around the world during the late ‘70s and early ‘80s. Mad Professor took that sound, distilled it into stompbox form, and turned it into the 1. The 1 runs from medium- to high-gain for sheer rock and roll aggression while a built-in ‘70s-style reverb effect lets you add just the right amount of ambience and depth. You can get an instant dose of legendary rock guitar sound with a single stomp.

The Big Tweedy overdrive guitar effects pedal from Mad Professor takes its tonal cues from the super rare High Powered Tweed Twin amp. You get the same fat, punchy mid-range and bite you’d expect from a vintage ‘50s American tweed amp. The Big Tweedy’s tone is very touch-sensitive, too; once you dial in your preferred gain level using the Drive knob, you can still use different picking attacks and your guitar’s volume level to fine-tune it even further.

The hand-wired Little Green Wonder from Mad Professor is the perfect stackable overdrive to slip into your pedal chain. This guitar effects pedal serves up a low compression, high headroom overdrive that works extremely well with high compression amps and pedals. Use it as a standalone overdrive or as a filter for pedals that may be a bit too rough on your amp. The Little Green Wonder features the regular complement of Volume and Drive controls plus a dedicated Body knob that lets you adjust your tone’s low-mid content and treble.

A vintage four-input Marshall in stompbox form. That’s not an exaggeration; Mad Professor replicated a complete amp signal path and crammed it inside their Loud’n Proud guitar effects pedal. The Loud’n Proud also has the same moderate amount of gain a Marshall amp has, along with a boost/fuzz to kick the medium-gain overdrive circuit an extra kick. The fuzz itself is designed to sound like a germanium fuzz, giving you the classic tone of a germanium transistor plus Marshall plexi combo.

The Sweet Honey Overdrive guitar effects pedal from Mad Professor was built to push already distorted amps past their breaking points. It also works well for adding a light, subtle overdrive to a clean channel. The Sweet Honey Overdrive’s highly dynamic and touch-sensitive overdrive tone can be controlled using your picking attack and your guitar’s pickup volume. Pick softly for a clean sound and hit those strings harder to make the Sweet Honey Overdrive growl.

This modern redesign of the famous Marshall Bluesbreaker overdrive guitar effects pedal faithfully captures the tonal characteristics that made the original one of the world’s most well-loved stompboxes. The BB-2 Bluesbreaker serves up everything from a subtle “tube valves starting to break up” drive to scorching hot lead tones. To make the BB-2 Bluesbreaker even more versatile, Marshall added a transparent boost function that can push your signal through the mix. You can switch between Blues and Boost mode via a rotary selector knob.

Finally, an overdrive unit that satisfies and transcends the demands and rightfully takes its place beside the iconic 808—the Maxon OD-9 Pro+ Overdrive. While building the OD-9 Pro+, Maxon sought the assistance of an advisory board of professional guitarists to craft a classic overdrive pedal. The OD-9 Pro+ efficiently serves as a four-voiced monster, providing you with anything from the vintage, bluesy tones of the legendary 808 to the fiery saturated chunk required by modern intense metal music.

The OD-9 Overdrive from Maxon may look like your classic fave, but the similarities end there. Enhanced circuitry with the JRC4558 IC delivers that creamy, smooth, and dynamic overdrive fancied by guitarists. Level and Drive knobs adjust the volume and intensity, while Hi Boost/Hi Cut tone controls set the brightness from smooth and warm to red-hot. From mild boosts to outrageous roars, the OD-9 gives you the most extensive range of valuable, noticeably tube sounds available.

Over the years, the 808 has taken on different incarnations and ignited the careers of several aspiring pedal designers wanting to create a better mousetrap. To celebrate the 40th anniversary of this legendary overdrive’s launch, Maxon, in cooperation with Godlyke, Inc., is releasing the limited-edition OD808-40. Boasting a remarkable collectible appeal and distinctive tonal characteristics, the Maxon 40th Anniversary OD808 is bound to take its place alongside the iconic units it has descended from. The OD808-40 is limited to only 400 pieces, each with a signed certificate of authenticity.

After setting the standard for overdrives with its legendary OD808, Maxon is now raising the bar with the Overdrive Pro. Special voltage-doubling circuitry delivers increased headroom, capturing the most transparent, warmest, smoothest overdrive you will ever find. The Overdrive Pro’s unique circuit reacts accurately to any playing dynamic and picking nuance, making just about any amp or instrument come alive. It consists of Level, Tone, and Drive controls. Your search for the ultimate overdrive ends with the Overdrive Pro.

The OOD-9 Organic Overdrive takes Maxon’s revived OSD-9 circuit and replaces the NOS 741 Op Amps with NJM (JRC) 4558s. Delivering an open-sounding, warm overdrive similar to the OSD-9 only with a more pronounced high-frequency response, the OOD-9 is ideal for livening up your dark-sounding amp or guitar. The OOD-9 reacts seamlessly to input level changes, giving a very interactive response to your dynamics. You can also stack it with other ODs to add character and clarity to their tone.
