Claude AI states: The EQ7 does not have its circuit type explicitly documented by the manufacturer as "analog" or "digital" in any official spec sheet I can find. However, I can give you a well-reasoned answer based on what is known: The EQ7 is almost certainly an analog circuit. Here's why I'm confident in that assessment:

• It draws only 10mA of current at 9V DC — a very low figure consistent with a passive op-amp based graphic EQ design. Digital processing pedals typically draw considerably more. Tonebox
• A 7-band graphic EQ using sliders is an extremely well-established and simple analog op-amp filter topology — the same basic circuit used in pedals like the Boss GE-7 and MXR 10-band EQ for decades. There is no functional reason to use a DSP chip for this type of pedal, and no indication in any product description or teardown that one is present.
• The very low price point and Ammoon's product line are consistent with straightforward analog op-amp designs.
