Buddy...about a year ago I asked you about how you set up the PQ3 for the Live Convention albums in 1977. You said you used it to boost the lower mids a little and all other settings were direct from the session 400. Do you remember what specific frequency you locked into and how wide you expanded it? I have one of the older units and I find it very valuable for fine tuning the tone of an amp. And it's quiet.
This is asking alot from the memory bank. Perhaps that cell bit the dust by now?
Thanks
Dennis
