I love surf music and I thought that was pretty great.
My only nitpicks -
More spring reverb on the guitar. Not much, but a little more.
The bass is kind of mushy, but it sort of fits, so if you want to make it better that's cool, or leaving it as-is is cool too.
As much as I liked it, it did get a little repetitive. Even for such a short song. Taking that main melody line somewhere else as the song went along would be good in my opinion.
Good job though. what the guitar chain?
