You can't take any signal from a point directly connected to an inverting opamp -input as it works to maintain that at 0v. It should be silent except for a tiny error signal. Elsewhere in the scheme, you have 2 opamp buffers that are not necessary (one opamp can driver several paths), so why not use one as a mixer for a "clean" delay output?

Have you solved those earlier problems yet?
