The Lemon Drop aka 7 Series Overdrive is a simple and effective “fuzzy overdrive” designed to capture the sounds of the Vox 4 and 7 Series amplifiers.  Used by Revolver era Beatles and Page on the second Zep album, these were hybrid amps with a solid state preamp and tube power sections that produced a unique tone heard on tracks such as Paperback Writer and Whole Lotta Love.
