Delay tails and 4049 clock

Hey,

I am in the process of designing my first boards with the FV-1.

I'll be making a delay pedal and want to add tails to the delay when bypassed. Can anyone advise on a schematic I can use for implementation of this?

I am also looking at using a 4049 as a clack module but can not find how to use this instead of the crystal.

If anyone has schematics for these I would really love to see them.

Cheers,

Mark

1. disconnect only input then pedal off. output is always connected
2. pin 10 = oscillator input , pin 9 = not connected.

Thanks for you reply, but all of that has gone over my head. Could you please explain in a little more detail?

igorp explained it perfectly.
1. Tails means that the input to the delay line should be disconnected (bypass footswitch) but the output of the delay stays connected to allow the echo tails to continue. Google it. True bypass does not do this but it is just as simple.

2. see this, http://www.spinsemi.com/knowledge_base/xtal.html Build your 4049 clock and connect the clock output to pin 10 whilst leaving out the xtal parts.
