Nord Modular G2 Inspection and Maintenance

Hi,

I have acquired a Nord Modular G2 from Reverb and am wondering where I can send this in the states to get it inspected and serviced? The display light’s are extremely dim and the audio output ports have a lot of hissing and static sound that is unpleasant to the ears. The headphone output port sounds good though… Please HeLP!

Best,
Thinh
