Gain Boost Question Pin 1-8

[RookieRecurve]

I haven't finished my amp yet, but the option of having a gain boost sounds fun.  I discovered that the gain can be adjusted by adding a resistor in series with the 10uF capacitor.  In this case, a 1.2K resistor in series, will result is approximately 50x gain (as opposed to the 200x with no resistor).  I am confused however about what to do with pin 7?  In this schematic, it shows that pin 7 has a capacitor labelled as "bypass", and the lines are broken.  Can anyone please shed light on this?  I think I will do this mod, and make it switchable to have the option of a gain-boost.You cannot view this attachment.

Yes 10uF to Ground is fine.
Just google "Smokey Amp Schematic" will give you many schematics using LM386.
Have fun with it.

Pin 7 is unused on the Honey Amp.  Most times it is completely unnecessary unless you have a really dirty power supply.  I haven't had any issues with any of my prototype of production honey amps not using pin 7.

Thanks Raymond.  After getting mine up and running, it is very quiet, so the filter cap on pin 7 is definitely not required in my case.  I will hopefully get the 50x gain boost connected to a switch soon enough to see what that is like.
