If you've spent any time chasing the elusive perfect tone, you know how frustrating it can be to find an overdrive that doesn't completely hijack your guitar's natural sound. Enter the Greer Amps Lightspeed Organic Overdrive.
Here at Cottonwood Music Emporium, we see a lot of boutique pedals come and go, but the Lightspeed is different. In fact, it secured the #1 spot on our Top 10 Best Selling Guitar Pedals list for 2024 and it's still one of our top selling pedals. It is a pedal that has become an industry standard for players who want to push their amplifier into the sweet spot without losing the unique character of their instrument.
Let's dive into what makes the Greer Lightspeed a must-have for your pedalboard.

The Greer Lightspeed is a low-gain, organic overdrive pedal designed and built in Athens, Georgia. When we say organic, we mean it acts as a true extension of your existing tone. Instead of masking your sound with aggressive clipping or a heavy mid-range hump, the Lightspeed preserves your natural EQ while adding rich, complex harmonics.
Whether you play a Stratocaster into a pristine Fender clean channel or a Les Paul into a roaring British stack, the Lightspeed respects your core tone.
Because of its amp-like nature, the Lightspeed is incredibly versatile. Here are the three most popular ways our customers use it:
Don't just take our word for it, the Lightspeed has earned universal acclaim from touring pros and gear critics alike.
"It excels at coaxing complex dirty tones in the low-mid gain range, and it can be set up for use as a transparent boost, or to throttle a tube into full-bodied breakup. If you value clarity, definition, amp-like grit, and responsiveness, the Lightspeed may well merit a little extra investment." - Premier Guitar Magazine
Customers constantly praise the pedal's articulation. The consensus is clear: it provides a rich, dynamic sound with excellent clarity, making it the ultimate tool for both clean boosts and natural overdriven tones. It is no surprise you will find it on the pedalboards of touring musicians like Peter Stroud (Sheryl Crow), Alex Weeden (Miranda Lambert), and James Duke.
No. Unlike Tube Screamer style pedals that heavily boost your mid-range and cut your bass frequencies, the Lightspeed is famous for its transparency. It preserves the natural EQ of your guitar and amplifier rather than reshaping it.
Yes, the Lightspeed can be powered by anywhere from 9 to 18 volts. Running the pedal at 18V provides more headroom and less compression, which is ideal if you are using the pedal as a clean boost.
Because of its touch-sensitive, amp-like nature, most players place the Lightspeed near the beginning of their overdrive section. It acts as an excellent foundational pedal to run into heavier drives or fuzzes later in the chain.
The Freq knob is the Lightspeed's unique tone control. Set at noon, it provides a slight increase in mid-presence. Twisting it clockwise emphasizes high mids, while rolling it back brings out a warmer bass presence.
There is a reason the Greer Amps Lightspeed was the only pedal from our 2014 best-sellers list to remain on our 2024 Top 10 list a decade later. It isn't a trendy circuit; it's a modern classic. If you love the sound of your guitar and your amp but just wish you had more of it, this is the pedal for you.
