Was that included with the RS1i or is it only included with the GS and PS 1000 series?
Thanks for your sharing! My Rs1i only come with a short cable adaptor from 3.5mm to 1/4. I think 15'cable is only included with gs1000 and ps1000.
Th RS1i/GS1K/PS1K all came with both the 1/4">1/8" adapter and 15' extension cord.
