Hello guys. I already build a few EQs on a test board and i obtained quite interesting results. I will fit the EQ with trimmers so i can tweak them to my liking. I am currently drawing the first PCB for the playback amp and i will try to post it here. Please tell me if i missed anything, any feedback is appreciated.

So the few things that i know that are missing here are the muting circuit and the swtichable gain for 9-19cm/s that i plan to fit on the second op-amp.

I tested this circuit and it sounds excellent compared to the original one.
I will now build the recording circuit, so that i can measure the response of the complete circuit.
