Ibanez Mikro---D'addario Chrome ECG25 guitar strings ( E .052) Downtuned to C. Used a pick. Bass into Zoom B1on and then to H2n Zoom recorder. (I'm not a guitar player but gave it a whack anyway) Backing track is a Yamaha Tyros. Bass on this is Yamaha track..not me. Chromes were smooth but way too stiff for my liking so I'll be putting different strings on.
