The Lester G is the ultimate rotary speaker emulator packed with goodies like a specially designed compression circuit to supercharge the rotating speaker effect on guitar.

Vintage Guitar Magazine writes that, “The Lester G just might be the slickest rotary-speaker simulator we’ve played…” They go on to say: “On the Slow function, chords shimmer with a chorale effect, as if you had a choir of angels replete with harps harmonizing behind you. Switching over to the Fast circuit, the sound ranges from a sweet tremolo to a full-bore Hammond B3 sound. You’ll even catch yourself looking over your shoulder for Jimmy McGriff or Gregg Allman.”

The Lester K provides stunning rotary speaker emulation in a compact package without the G’s built-in compressor making it perfect for keyboards or guitarists who already own a compressor.

Electro-Harmonix has unveiled the new Lester G and Lester K Stereo Rotary Speaker Emulators.

Lester G
There's nothing like the sound of a Leslie® rotary speaker cabinet on guitar. That's why legendary players like Jimi Hendrix, George Harrison, Eric Clapton and others have relied on the iconic effect. Now, for those looking to get that unmistakable sound with the convenience of a pedal, EHX introduces the Lester G: ultimate stereo rotary speaker emulator for guitar.

Don't miss Bill Ruppert's jaw-dropping video featuring the new Lester G.

Lester K
We're also pleased to introduce the Lester K stereo rotary speaker emulator designed for organ-type keyboards. The K doesn't include all the Lester G's features like a built-in compressor, but for guitarists who already own a compression pedal, it kicks butt! Watch guitarist Jon Skibic put the Lester K thru its paces.
