Ibanez DE7 output level?

I just got an Ibanez DE7 echo/delay and I like the sound of the echo but the dry signal for some reason is slightly boosted and I don't like this. 

Here's the schematic:

Could I lower the dry output by lowering the value of R16, reducing the gain of IC7A?  Or would that also reduce the echo level?
I'd like to maybe add a trimpot to adjust the dry level.

Any ideas?

ooo nice I've never seen a schematic for the DE7. I love the shit out of that pedal, but isn't it SMT stuff in there? Sounds pretty hard to mod?

no, normal components, i've began to change most of the crappy ceramic caps.

there also a mod concerning the delay/echo switch, replacing it with an one meg pot to have a multitude of sounds between delay and echo.

Yeah, I found that mod, it looks interesting.

Cool. Easy to do? Have any pics or soundclips?

i don't know, i've not did  do the switch replacement yet...

bump.

I'm interested in modding my DE-7. I had some ideas - possibly adding a tone stack somewhere to filter the repeats...I thought about adding some diodes if possibly, something to simulate lower-Fi repeats....

Any thoughts?

Possibly adding another delay pot - two have two and then then a switch to change between them to get different delay times...?
