I think lm4250 is single opamp.. you cant used it in this circuit.. or else make another layout that has 2 lm4250... :D


I used LF442 in this circuit because I could not supply LF441 regrettably :( LM4250 is for bajaman's active humbuckering preamp project :thumbsup

Morning,
is it possible to bring the Frequency down for Bass?
Maybe 180 to 800 Hz?
