My presets knob on my Spider IV 150 has been loose for some time, and I hardly use it I usually use the directional pad thing next to it, but it is completely loose, it's not connected to anything, and I need to know how to fix it myself, if possible. I need my head in comission asap so if you guys could help me out it'd be really appreciated.
I would recommend bringing it to a factory-authorized service center. I doubt it is the 'knob' itself, but more likely the actual control potentiometer that the knob adjusts. Only way to tell is pull the chassis out and test it.
