I've seen a lot of tabs for I've seen a lot of tabs for this song on the internet, but all they ever give is the bass rhythm for it. So I decided to tab out the full song, including the oft-ignored solo and chorus.

You can play Opticon in drop-D, but I prefer to play it in what I call drop-C, which I use for all Orgy songs. To drop-C tune, drop the E string down one and a half steps (three frets) and the A and D strings one half step each (one fret). I leave the g, b, and e strings in standard tuning because the highest note of the solo is played on the 23rd fret, and I have a 22 fret guitar, so I have to bend up to the note. If you want to play the song in drop-D, just play anything on the E, A, or D string one fret lower.

For the intro, just do a big slide down the neck at the appropriate time (just listen to the song) into this-

Intro (w/heavy distortion)
C--\4~4-4-2-4~4-4-2-4~4-4-2/7~6~6\--|
A--\4~4-4-2-4~4-4-2-4~4-4-2/7~6~6\--|
C--\4~4-4-2-4~4-4-2-4~4-4-2/7~6~6\--|
Then just slide off the neck

Verse
C--4-4-4-4-4--4-4-4-2-2-2-4-4-4-4--|
A--4-4-4-4-4--4-4-4-2-2-2-4-4-4-4--|
C--4-4-4-4-4--4-4-4-2-2-2-4-4-4-4--|
Then just repeat the 4-2-4 part until the guitar and bass cut out.

The rhythm for the chorus is played the same as the intro. I prefer to play the synth line for the chorus, which is as follows-

Chorus (w/heavy distortion, reverb and chorus)
e--19~19(b^)20(r)19-19-17~17-19-19(b^)20(r)19~16~15~--|

Fill
C--9~9--9-9-7-9~9-9\--|
A--9~9--9-9-7-9~9-9\--|
C--9~9--9-9-7-9~9-9\--|
End the fill by doing a quick slide up and down the neck.

The second verse is played exactly the same as the first. I only play the little synth piece below, because it screws up the rhythm of the song if you play the verse, then switch to the synth fill, and then back to the verse. The synth fill is as follows-

Fill (w/heavy distortion, reverb and chorus)
e--11-10------------------|
b-----------13-11-10~--|

For the second chorus, just do a big slide up the neck into the chorus synth. Then play the verse once during the breakdown, and then go straight into the solo.

Solo (w/heavy distortion, reverb and chorus)
e-----------------1----------5---6---5----6\5/10~11~8~---|
b--1-1------------1/4--4---4---4---4----------------------------|
g--------0-3-----------------------------------------------------------|
C--------------4-------------------------------------------------------|

Second Part
e-----8---6------13-----11--------17----18----17------18\17/22(b^)23~(r)22~20~--|
b-------8--------------13-------16-----16----16-----16----------------------------------------------|
g--5----------10--------------------------------------------------------------------------------------------|

After the solo just go right back into the chorus. For the last verse of the chorus, I drop down and play this-

e--7~7(b^)8(r)7-7-5~5-7-7(b^)8(r)7~/10~9~--|

The outro is just a rhythmic variation on the 4-2-4 verse line with a little wah mixed in. Just listen to the song, the pattern is easy to pick up.

I play Opticon using a DOD Death Metal distortion pedal and a Zoom 506II bass effects processor, and the sound I get is surprisingly close to Amir's synth sound. If anyone is interested in the settings on the Zoom, feel free to e-mail me at zorg200@aol.com. Otherwise, play loudly and enjoy.
