In case it's of interest, this recording was made using the Mk I ARiAB (passive) prototype. Recording made in the autumn of 2005 at Roberto's "Nivram Room" home studio.
Guitar: Pistolesi Spacecaster (1962 style with rosewood slab fretboard), fitted with 12-52 strings (wound third).
FX1: Meazzi tape echo (c. 1962).
FX2: ARiAB Mk I prototype (switched in throughout).
Amplifier: Replica of 1958 Fender Tremolux (built into a Gibson tweed cabinet).
I hope it helps give a faithful impression of the sound of the ARiAB.
NB: The melody played differs slightly from The Shadows' version, more closely following the Dmitri Tiomkin orchestral / choral version as heard on the film soundtrack.
