1. therefore will not crash to the stage floor if the grip on the SRG is lost during operation 2 3 String Mounting amp Tracking Place the guide rails on the 2 support strings with the support strings on either the inside or outside of the Fangs depending on the string spacing of the instrument The SRG should rest absolutely level on the guide strings and never tilted to one side It s important to get a feel for the optimal positioning of the SRG through persistent practice Proper use of a cello bow is not learned in a day and neither is the proper use of an SRG both take practice 2 4 String Driving String driving resonance will initiate immediately after holding the SRG steady and level on the support strings Any deviation from top dead centre above and parallel to the driven string will result in various effects the most obvious being fade in fade out and reverse envelope effect All positional effects are a result of deviation from parallel top dead centre above the driven string The best path to finding desirable effects is through constant experimentation 2 5 Input Transducer Effects Various Legato and Staccato effects are possible through the proximity and forward backward angular relationship between the driver and the magnetic core of the input transducer pickup on the instrument Most useful effects depend on this distance and angular relationship Provoking the input transducer in every conc2.

5. ng produces some very interesting special effects available only tothe SRG 2 OPERATION 2 1 Instrument Compatibility The SRG functions on any stringed instrument with ferromagnetic strings including plain steel strings and steel core strings The is equally compatible with light gauge string instruments such as guitar and heavy gauge bass string instruments The tracking rails the are optimised for bass instruments accomodating bass string spacings of 16 22 mmon the outer rails as well as light gauge string instruments with string spacings of 8 12 mm on the inner rails The unique Fang rail design allows more stable and accurate string mounting and tracking A minimum instrument pickup to string clearance of 4 mm is recommended The SRG is also capable of driving Acoustic Steel String Instruments without electromagnetic transducers although the tonal effects are less audible and transducer proximity effects are unavailable Bowed String Instruments such as Cello or Contrabass require a resonator and solid steel core strings helical core strings do not contain enough ferro magnetic mass to be inductively driven 2 2 Handling The SRG V Series is designed to be handheld between the thumb and ring finger with the index and middle fingers free to operate the triggers with the LED facing towards the nut of the instrument The V3 is securely tethered to the cable of the AMX Armband
