Any simple circuit to send different frequencys to different pedals?

Im familiar with building pedals, but haven't designed any. Any ideas on how to simply devide the signal into bass and treble, and send them to different pedal circuits?

thanks

Sure, that would be an electronic crossover, like they use in PA systems. In fact, you might just borrow one of those to experiment with the concept to see if it does what you hope.

A crossover is nothing more than a high-pass filter and a low-pass filter put together. The input feeds both, then the outputs are hoghs and lows.

thanks, ill mess around with that.

Um... HIGHS and lows, not hoghs... sorry

Note that highs and lows can vary substantially in terms of levels. Typically, "highs" have a fraction of the amplitude that lows do. That will depend on how you define "highs" and "lows" though. If "highs" for your intended application start around 2khz then you may want to add some gain to the upper signal in addition to merely splitting it.

The other thing is how clear a distinction you require. Active crossovers vary with respect to the sharpness of the boundary between different bands. Use of two-pole highpass and lowpass filter sections will still have considerable signal content, that is classified as part of the "highs" output, still be lower-frequency stuff. You probably need to think about how abrupt a disctinction you need to make before launching into any purchase or construction project. It may be that 2-pole is fine, but it may be that you need 6-pole.
