VHX IR and power-amp

[tayistay]

Is the VHX's IR recording output based on an attenuated power amp output? How does the recording output include the tone shaping of the power section? My understanding is that the DSP is between the preamp and power amp, as in a standard serial effects loop.

thanks!

No, power amp is not affecting to IR output.

Yes, DSP is between preamp and poweramp and output tubes will be deactivated in cabless operation.
However the poweramp controls (Deep and Presence) will affect the IR output as well thanks to a mixed analog/digital design, so only power tubes and load (speaker) won't affect the IR ouput.
