It's been on my gig board for a couple of years with no issues. I try to power the board off a least a minute before I have to move it - that hasn't been a problem either - there's always other stuff I can tear down and load out first. It takes me longer than a minute to case two basses, for instance...The Compressore is rugged. I doubt the tube would really become much of a problem.
Nothing much can be done about the size nor the 1A of 12V the tube heater needs, of course...
But at last weekend's gig I used my small board with the Becos Stella with a touch of tape saturation and liked it fine.
). Anyway, ive done transparent and want to try colored/tone enhancing. The added sustain you mention is what makes the Corset interesting... I really want to try the Smoothie too but the price difference is significant so maybe the EHX is good enough?
