Exclusion Criteria: * Any factors that might prevent the subject from completing a full course of therapy with the Resonator™ device, or from attending any of the scheduled study visits, or from completing any of the study measures. * Subject suffers from co-existent chronic pain condition(s) of non-fibromyalgia origin, such as osteoarthritis, low back pain, neck pain, painful diabetic neuropathy and postherpetic neuropathic pain, that cannot be distinguished in severity and/or in type/sensation of pain from the pain originating from the subject's condition of fibromyalgia. * Any other significant comorbidities that might impact the ability to evaluate the subject's satisfaction of the ACR 1990 Criteria for the Classification of Fibromyalgia, or for the subject to complete any of the study assessment tools. * Tender point injections received within the prior one month. * Current or past history of major psychiatric disturbance (e.g., schizophrenia, bipolar disorder, substance abuse). * Known inflammatory rheumatic disease. * Epilepsy/history of seizures/taking medication for epilepsy. * HIV and other autoimmune disorders. * Active cancer or treatment for cancer within last 6 months. * Active infection(s). * History of ECT * Uncontrolled Hypertension. * Advanced Pulmonary Disease. * Unstable cardiac disease. * Prosthetics or implants comprised of ferrous metals. * Pacemakers, vagus nerve stimulators, or other functional electrical stimulators such as those commonly used for pain. * Consumption of more than 21 alcoholic drinks per week. * Pregnant, breast feeding, or planning pregnancy prior to end of study participation. * Developmental disability or other cognitive impairment that would in the judgment of the PI impair adequate comprehension of the informed consent form or complete any of the study-related activities. * Worker's compensation, receipt of disability or present/past litigation for monetary compensation pertaining to subject's fibromyalgia condition. * Participation in other research within 30 days of study enrollment.
