Good day gentlemen,
I before you today to ask assistance with a build I am doing for a dear female friend of mine.

I build a Emma ReezaFRATzitz RF1 following this layout http://tagboardeffects.blogspot.de/2012/10/emma-reezafratzitz-rf1.html
I did the modiefied version with extra bass and mids, which turns out to be where the problem lies.

Now the general pedal works and sound pretty darn cool to me, but the two extra controls donĀ“t work. I did check the connections to the pots and the positioning of the parts multiple times and will do so even more until I somehow get this to work on the chance I overlooked something.
I also sweeped for micro bridges, but to no avail.

Would you have any concrete idea where to look or what might have gone wrong? I really am at a loss here. If the pedal was not working I could audio probe and such, but in this instance that is useless.
A complete reflowing is still open, but if I could circle in the aera first that would be pretty cool.

Plus I have another issue, dunno if they could be related, but when the pedal is in bypass (buffered) I get a bleed from it, so I get distortion when the gain is turned up. The LED indication is off when this happens.

I hope you can help me (and by extension her) oh whise men!
Thanks a lot in advance.

Cheers
Kiichi

Update: Continued to check everything and did a reflow on the lower part of the board where the changes to mid and bass controll come into effect. This fixed that problem! Hurray! What a great sounding pedal.

However the bleed is still there. Anyone got an idea on that? If not I will just do a complete reflow and if that does not help convert the pedal to true bypass, though I would actually like to keep it buffered.

mmmmm, frustrations. revolutiondeux is one of those sites I go to just to wait for the page to finish loading, even though there seems nothing happening. tagboardeffects is another. and that diagram has all the pots drawn as trimmers, and no labels on them.

Anyway, the problem seems to be in the switching circuit, which is not described, either in the OP's posts or elsewhere.
