Shy and coy, Eveâ€™s tremolo tone is delicate, musical and hypnotic. Able to offer everything from a light pulse to a deep throb, Eve encapsulates the idea of a simple, super musical sounding trem. Seven years in conception and finally realized in 2011, Eveâ€™s siblings: the Seven Sisters, are a revolutionary new concept in the realm of guitar effects pedals. The worldâ€™s first rechargeable guitar pedals â€“ the Sisters feature a Lithium Ion cell (like that found in your cell phone or digital camera) and internal charging circuitry. Simply connect Eve to a regular guitar pedal power supply, charge her for four hours and Voila! 120 hours of actual use! The Speed dial controlsâ€¦â€¦. Tremolo speed. Depth controlsâ€¦â€¦.. Tremolo depth. An internal trim offers an overall gain control â€“ allowing an optional signal boost. The tiny sisters have the Worlds smallest pedal board foot print â€“ simply meaning they take up less space on a guitarists pedal board than any other available battery powered pedal.
