Switching question

[diablochris6]

So, the BIT:Legend of Fuzz I built a while back has been diminishing returns for me; its been getting more sputtery and gated every time I plug it in.  I am thinking about getting rid of the vero and creating a pcb of it to be cleaner.  I know that the BIT was a Silver Crank going into a GZ, so I was thinking of adding a toggle switch so I can have both circuits in series (a la the BIT) or just the GZ section of the circuit.  The question I have is, do I need any extra parts to prevent damage to any of the Silver Crank components when just in GZ mode?
