MID BASS boost

[wavenator]

ok i want to build some simple mid/bass boost
or treble cut
or low pass filter
whatever you want to call it

i am using my metal muff
and i want to cut more trebles
i want to build something simple
do you have any thing to give?

Treble cut sounds like what you want.  Look at the "stupidly wonderful tone control" or SWTC.  Or the FAQ has something about tone controls I think.

I thought you wanted something simple? 

Like this (supposed to be a 10k potentiometer):

Input--- /\/\/\/\/\/ -----Output
                  /\
                   |
             Capacitor (18nF)
                   |
              Ground
