10 band eq based on 6 band eq

[Tommygun011198]

hi all, im looking to build a 10 band eq based on the 6 band eq pcb. im wondering if this would be achievable just by adding another tl074 quad opamp? would it work if i added another tl074 and bandpass filters like the below, and then adjusted the values of the existing ones to new frequencies?

im using https://www.muzique.com/lab/gyrator.htm to calculate the frequencies

Should work fine. You may want narrower Qs if you start bunching the frequencies up.

See if you can get a 10-band schematic and have a gander at the associated values for each band. Steal from the best.

thank you! this is the first time id really looked at filters in more detail, hadnt even realised what the Qs was! thanks for the suggestion thats really helped my understanding!

thanks for the suggestion, this is a great idea and saves me a bit of time with the numbers! ill probably use the values from the MXR EQ pedal

This would probable be a good place to start
