I change quite often and I happened to spot this particular hard case very cheap, which was of a much better standard that most of the bendy bottom hard cases about, so I'm jumped on it and decided I'd try and stick to just this one "pro" ish case and its dimensions. For live jams and whatnot I'd simply take the usual four or so on the Pedaltrain mini as its very convenient, a BCB-6 if I needed more scope perhaps. But for a pleasure and (if) my doing own music this has "the sound" immersion that I can play for hours. But if I'm honest I need to add more..
I thought I'd made a big mistake tonight as I turned on the power (first test) and half way through realised I had not turned the 18v taps down to 9v!! So two pedals were getting rather more voltage than they should, including a BBE Mind Bender that arrived only yesterday

Luckily after dinner I rechecked and no harm done..phew...
My current school of thought is also for ease of use recording wise, and for not being put away forgotten in boxes, I should put my favourites in seperate cases ready to go, all powered up.
