Update:
I have added output XLRs for 1&2 (Mains) - with short XLSs @ the QC and Jacks for 3&4 (Headrush monitors);
relocated the Polytune;
replaced the old MIDI cables by Widi short angled ones;
added a « elbow up » USB-B adapter to the QC
I still plan to try the CryBaby wah mod to replace the « Wah » expression pedal. Wah models experience and setup - #8 by ScreamOfAnger
