Hey guys is there a difference between the Marshall DSL and the TSL? I have the DSL 50, which I like but there's not enough head room when I start to push it. I have a friend that will sell me a TSL 100, but he lives a few hours from me so it wouldn't be to convenient to go and get it for a gig. I heard that the DSL was a better amp all the way around and if this is true I'll just buy a 100 watt head. I always thought they were the same with the exception of one extra channel.
