Where is the super rod in Pokemon Silver?

in vermillion city

Improved: After you defeat the elite 4 then get you National Dex go to Vermilion City and go to the house left of the PokeCenter. When you enter talk to the guy standing there and he'll tell you to catch the biggest Magikarp for the Fishing Guru of Lake Rage. Catch the biggest one you can find and give it to the Guru of Lake Rage and he'll give you a Super Rod.

Never mind. The answer I had on here was how to get the Super Rod in Soul Silver.
