or treble cut
or low pass filter

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 found this schematic
and i already built it
i just wired pin4 to 0.01 mf from pin 3
it doesnt work
i dont have bipolar power supply
i have any chance to get it work?
