+1 on the Boss. Been using one for nearly 6 years and its not once ever let me down. Infact my whole band(me, two guitarists) each have one and we're always perfectly in tune. I think unless you are a total tone snob with ears like a thing with VERY good ears you never notice any tone suckage of volume being stolen, I certainly have never noticed any difference and the guitarist I have been jamming with who only uses high end "Boutique" gear and who Is a total tone freak uses one.
I've had beer all over mine, its been dropped and had things drop on it, its been left in freezing band vans and been left in the boiling heat of a summers out door gig, infact it was so hot to the touch from being left in the sun that it was hard to pick it up. Its been thrown in various gear bags and boxes with a bunch of other rubbish and it still functions perfectly, all scratched and dirty b ut it does its job. If it ever does die, I'll get another one in a heart beat.
