FL-9 modifications

[Mobisimo]

Hey all,

I just came by an Ibanez fl-9 flanger.  It is a pretty good sounding pedal, but there are definatly improvements that could be made.  Does anyone have a schematic or experience with modifying these?

Thanks in advance.

What improvements would you like to make?

I haven't played mine in years, but I recall it sounded cool, but noisy.

Hey, thanks for the reply.

Mine is rather quiet in my opinion, so that isn't an issue.  I find that the flanging is a little thing, and a little erratic.  Sometimes you can hear it a lot and other times it is almost inaudible.  I would like to thicken it up a good deal.  I figure this has to do with increasing the gain and bass response.  I imagine an easy way to increase the bass is by raising the input cap.  
Also, I think the bypass is terrible.  Is there anything I could do about that?

Thanks.

I'm gonna fire this baby back up to the front page.

Strange that it's quiet, this pedal is famous (like it's other 9 series brothers in modulation) for a gain boost when engaged.  Mine is no exception.  Bypass is also considered pretty good on these pedals.

It is a very chorusy flanger though, much more subtle than most unless you dime everything.

[Mobisimo]

Agreed about the chorusy part.  I guess the other stuff is just a matter of opinion.  The noise doesn't bother me, but the bypass does.  I set to work trying to get some ic sockets in there so I could use some opa2134s, but everythings so crammed in there.  
Anyone experiment with the trimpots at all?

Just found out that the input impedance is only 500K, which is a bit low.  Upgrading the input transistor might do the trick.
