It's supposed to be regular guitar amp, so I figured for 10M ohm and 1M
ohm - got the same answer each time in terms of attenuation.

The manual list the output impedance of the Repeater as 1K ohm.

Put that 1k between the left Tip connection and the left 2.2k, and
calculate the attentuation from that. Note that to get the
attentuation ratio at the left 2.2k, you have a 1k in series with the
parallel combination of 2.2k and 3.9k+2.2k. I suspect the result will
be very close to the claimed 12dB.
