It's still cooler than the air in the amp. It's all relative.
Even on a really hot day when my PC is pulling in room air at 26C - that is still way cooler than my Graphics Card that can hit 80C.
As long as the delta (difference between the unit and the air) exists there will be heat transfer / balancing.
Cold air would be better, but any cooling is better than none.
Strapping Young Lad, some Meshuggah
Gojira, Slipknot
All depends on the vocalist really. Some SYL tunes are heavier than Cannibal Corpse, but DT's an actual singer.
I will do that when I get a mo. They are quite different.
What I might also do... in September my big band is hopefully getting back together. I might do the first 3 rehearsals with a different amp and see what happens. Same bass / compressor etc so just the amp is changed. I'll see if I can get permission to stick a room mic up (have to ask as kids are involved) and get some recorded.
How would we all feel if the guitarist’s guitar failed and we couldn’t play the gig?
Same as they would feel if we let them down in a way that was easily avoidable
That's False Equivalency.
Taking a spare bass is not the same as needing another van full of kit.
PA failure falls into the same bracket as a complete power failure - nothing you can do about it.
But you can do something about a bass failing - use a spare.
Forgot to say, it does come with the official case.
And don’t be afraid of making an offer. I don’t really have a clue how to price it. Other than when the necks alone come up on eBay / reverb they can make £600 on their own.
