Re: amp power ratings
i think most amps are usually rated a little conservatively, but yes, it should be 40 or a little more, when at full volume
however, with alot of amps, you can get to around 7, and thats as much actual (audible) volume as your gonna get, any higher and it just gets more overdriven
but ive read where old marshalls and hiwatts rated at 100 watts, have actually been tested up around 120-130 somtimes! heh......
