tone control pots?

:

arthur norris	tone control pots? Are all three pots in a 3-band tone control logarithmic? I notice that if I simulate the response of the Marshall or Fender tone circuits (3 band and 2 band), I can't seem to find a setting which gives a flat response... I assume if this is true that it is deliberate. I'm trying to improve the tone controls of my home-made amplifier-- any recommendations? thanks, art

Anders Westerberg	Flat response is obtained when all controls is set to 10. Anders

Doc	I believe you are mistaken. There is always a midrange dip on a Fender amp. The only way to appeoximate flat response is midrange full up with bass & treble way down.

Bill Bolton	> Flat response is obtained when all > controls is set to 10. There is no truly flat response position on the classic Fender (and copied) tone stack. Closest to flat is set with treble and bass set to 0 and mid (if fitted) set to 10. In tehcalssic Fender tone stack, treble and bass are BOOST only while the middle control is CUT only. Cheers, Bill

Dave H.	They work best for me with the bass and treb pots log and the mid pot lin. Also I think 250k is better than 1M for the bass pot. If you use 1M half of the pot rotation does very little. I am going to disagree with Anders and say that flattest response is mid 10, bass 0, treb 0.

Anders	Of course, you're right. I had minimum attenuation setting in mind. Anders

Jack Orman	Ys, it's true that with the "Fender" type of tone control circuit, there is no flat response setting. However, this is part of the sound that we have become accustomed to hearing and isn't necessarily a negative. regards, Jack
