dude, there are absolutely no mids on your tone, i dont know how did you manage to achieve that one
ok, here are my tips for you to richen your tone, expecially when using POD XT patches;
1- dont use any CAB simulations from your POD
2- just load up your favourite amp from POD and disable the CAB; you will get a raw, tiny sizzling amp tone, dont worry you're gonna fix that
3- while using amps from your POD, or writing your own tones, always keep the BASS knob of your amp as low as possible, have a considerable MID level and don't push up HIGHs too high either.
4- use a CUBASE or SONAR kind of a DAW instead of FL stuff
5- record your guitar with this raw amp tone loaded from your POD
6- always double track your rhythm guitars hard panned to left and right. you can even quad track them, depends on what you want to achieve...do not copy a single played track to another track, play them twice. if you insist playing them once for all, move one of the tracks a few ms apart from the other track. but that's not a good idea...track them twice at least
7- insert an impulse file reading vst like keFIR or voxengo boogex to your guitar tracks, load up your favourite CAB impulses which you can find a lot here on these forums
8- experiment with the settings of keFIR to achieve the tone which suits you best.
9- always try to achieve the bass of your overall sound with a bass guitar, not with your rhythm guitars.
10- try to color your guitar sound with parametric EQs, but don't overEQ your tracks, especially when it comes to HIGHs, you can get a muddy and disturbing sound very easily.
11- it may seem sounding nice when you EQ your guitars lowering the MIDs but don't be fooled with that. always have a considerable amount of MIDs on your tones.
12- when mastering with ozone or some other vsts, always be very gentle playing with the EQs, use very little amounts...
i think you may have a decent tone with your guitars if you pay more attention to my tips...
have fun tracking
