So I basically just took this chording from someone's that was already up. 
But I noticed that a lot of David Choi's songs use different chords than normal, 
so I thought I'd add in some tabs to show what chords he really uses in his songs.

E (022100@1)    Abm (133111@4)     F#m (244222@1)     B (x2444x@1)    A (x02220@1)   C#m (x13321@4) 
E  |---0-------0---------0--------0------0------0----|
B  |---0-------0---------0--------0------0------0----|
G  |---9-------4---------2--------8------6------6----|
D  |---9-------4---------2--------9------7------6----|
A  |---7-------x---------x--------9------7------4----|
E  |---0-------4---------2--------7------5------x----|

Also, he does a quick transition from his A chord to his F#m chord. I looks like this:

A (x02220@1)      Abm (133111@4)    F#mE (244222@1) |----0---------0--------0----------------|
B  |----0---------0--------0----------------|
G  |----6---------4--------2----------------|
D  |----7---------4--------2----------------|
A  |----7---------x--------x----------------|
E  |----5---------4--------2----------------|

When he's using the Abm as a transition chord [only strumming it once on the 4th
beat] I marked it with a star[*] to make it a little bit easier to understand. I'd hope you 
can figure it out without it, but if it helps, there ya go :P

E (022100@1)                       BI'm (x2444x@1)just listening to the clock

End on an E if you want, I don't know if he resolves it or not though.



hope it helps a bit :)
