Can anyone tell me what the output impedance values are for the HD500? Specifically, the effects send output impedance value and the 1/4" output impedeance value. I've tried looking it up on here and all I can find are the input impedance values. Essentially, I want to know if a buffer is necessary on cable runs coming out of the HD500. I'd like to compare output impedances of the HD500 to my buffer pedals.

Thanks in advance for the help - it's very much appreciated!
