i use a weber attenuator, with great success.
but i do it differently...
the rig:
guitar goes to the pedalboard, with the requisite overdrive, compressor, noise gate, tuner, wah and vibe....
that goes into a 1981 Mesa Boogie Mark2B 60 watt short shell head....
out of that, directly into the Palmer PDI-09, which is how i capture the sound that goes on the recording.
out of that, into a Weber Mass lite attenuator, so i can bring the amp volume down for monitoring at normal inside-studio levels..
out of the weber, into a AVATAR vintage closed back cab, with a Celestion Heritage G12.
i will mic that cab sometimes, using either a sm57, or a AT4033, and blending it with the direct Palmer sound.
A Yamaha DG stomp effects pedal, is in the effects loop of the boogie, which is great live, but i never use it for recording..
i always record bone dry, and add effects at mix down.
