In the ts9 which .047 cap is the one that grounds AC in the feedback loop?  I am looking to raise the value of it to increase bass response!  Thank You!

The one connected to the 4.7k resistor.

In which schem or layout? I know it's the one from the feedback loop to Vr.

I found it, Thank You very much!  By the way, what is a vr?  Anyways, I replaced the .047 with a .1 and it is incredible.  The bottom end is their now and it is not muddy at all.  I can't believe the effect this mod has on the ts9, why is it not more common?

DIY FAQ:

Well, V.R. is voltage reference and 1/2V+ is 1/2 of your most positive voltage (usually 9 volts). Usually they are one and the same and you can typically see V.R. connected to a resistor that connects to the input of an op amp as in the Shaka Braddah 3, The Rat and many others. Basically if you see 4.5V or V.R. or 1/2V+ ( all the same), you find all the places on the schematic that reference the label and connect them together. So all of the places that reference V.R. would connect together; one of the connections actually creates V.R. or 1/2V+. The connection that usually creates V.R. or 1/2V+ aka 4.5V (for a 9V battery) usually is a voltage divider. Typically two identical resistors, one to V+ (such as 9V), the other to ground. The place where they connect is V.R. or 1/2V+.

An example of 1/2V+ also known as V.R., V.B., VREF, 1/2V+ etc...
