ok i just transfered my circuit from breadboard to stripboard in the hope it was a bad connection, i have a better result but my bandpass filter doesn't seem to attenuate in the right place:

I have only built the bass section so far and i get a signal from about 90Hz but it doesn't attenuate till i get to around 5Khz, i was expecting it to start tailing off at around 200Hz?
also i am using a 1N914 instead of the specified 1N4002, will this have a detrimental effect?
The chip i am using is LM324 since i had one laying around instead of MC33204, i don't know if this could be the issue?
