Capacitor Identification

Hi

recently I managed to lay my hands on a citronic sm650 dj mixer which is considered by many to be a good sounding dj mixer.
Unfortunately I am finding the mixer a bit too bright and wonder weather this is caused in part by the capacitor used in RIAA op amps feedback loop.
I am relatively new to electronics and haven't seen a capacitor of this type before it is a 22pf cap (C45) on the schematic and wondered what its dielectric is. The only caps i can find at this value are either ceramic (not recommended for audio) or mica which by all accounts can sound a bit bright. i realise that the brightness could be caused by many other things but the mixer was cheap and i am having fun experimenting with different components.

Since owning the mixer i have replaced the smoothing caps with panasonic fc's they are not burned in yet but yielded a small improvement.
I have also tried changing the op amps from 4558 to TL072 or OP275. I am undecided which ones i like best but both are an improvement over the 4558.

So if someone out there could id this cap for me i'd appreciate it.

thanks
