There isn't actually a rhythm guitar on this track but if there were I think it would go something like this. You could also try tuning down a step to Eb and transposing accordingly giving you A instead of G#, D instead of C#, E instead of D# etc making it all open chords which sounds ok all be it not very ramones (but then nor is a string section).
