Fixing up and Old boss TWAH

[VintageGear]

Replaced all the capacitors yet? Inspect for corroded leads as well. Water is bound to have had some effect on the electronics. Anything looking dodgy: Replace or resolder. The components aren't expensive in this pedal at all.
What are you using to clean the board with?

I used contact cleaner.  (Carbon Tetachloride) electronic spray cleaner.

Update :   As i was futsing about the more i feared i might do more damage than good.  traces easily lifted.
                i swallowed my pride and had a freind who has vastly more knowledge and experience than me
                look at the circuit.    As of to date he has managed to bypass the fitflop switching and proven that
                the effect functions.       The problem is in the switching circuit.    it leaks the signal preventing
                it to go to the effects chain.     

                although id be happy to just slap in a 3pdt switch and be done with it.    he also said he will investigate
                the fitflop.
