Some more thoughts on the Racks/Aircraft/Fly-in gigging....
I'm trying to be as objective as I can while being as subjective as everyone would be
My Rig (Furman PL-Plus, Triaxis, MPX-G2, 2:90 > SUS4 6U Shockmount Case) is ~50kg. Add another ~10kg for the R1 Floorboard incl an extra Rocktron Hex Expr-pedal, all in a tailor-made flight-case as well....
I can easily put it into my BMW Compact (plus a 2x12 or 2 1x12s and 2 guitars) and haul it around, no probs.
But with Air travel luggage weight limitations ( commonly ~20kg for checked-in luggage plus 6-8kg for carry-on/cabin) I'm way too far down the road with my rig.
Only once for a couple of out-of-area gigs were we allowed to bring whatever we wanted at no extra cost. We even got our own HCU-6/E air cargo pallet for our stuff exclusively...that was the exception and just a tiny bit of a Flight666 feeling for all of us....
My usual and normal approach for fly-in gigs is to check out with probable bands that also gig there what backline is avlbl and might be shared/used.
Common systems (that I came across) are Marshall DSL/TSL/JVM410s, Boogie Rectos, Engl Fireball/Powerball...
I had to ask myself "Do I really need my complete rack?" for a fly-in gig? Will the folks in that club/bar/open air/... really notice me for my signature sound/personlized gear? Imagine yourself in the first or second row listening to a band.... If the band sounds good and puts on a show I'm golden.
Do you need your personal complete setup for the band to sound good as band? I doubt that.
I started with a Boss GT-8 to be hooked up 4cm for Fly-In gigs...pre-programmed at home and then only slightly tweaked to fit the local environment at sound/line check.
For the last couple I only used a tiny board with a Mooer OD, Mooer Chorus and 2 Mooer Dly pedals (all those tiny really good sounding pedals)...did the job and was 4kg tops.
Over time I now know how to dial in lots of amps to get a tone/sound that makes me feel as comfy as possible while making the band sound as a whole.
Domestic gigs still get the full 60+kg of personal subjective tonal comfort zone though
Just my 2 cents...
