The OP-AMP can be any single small noise op-amp, the original NE5534 is used. The 2N44 is probably to get replaced by other PNP germanium transistors without having much change in sound. The switching factor has been omitted from this diagram, but you almost certainly wish to add a bypass of some varieties to this impact.
This emphasis switch chooses a tone taste, this may very well be expanded to incorporate a wider scale of frequencies, but too tiny a capacitor value could lead to oscillation.
All tame a company internal confirmation of this impact has long been omitted, nevertheless it can be easy to add. This could be noisy, according to the platform, to ensure the capacitor with value 10-15pF may very well be positioned inside a cycle of OP-amp if you're apprehensive an excessive amount of squeaking.
