Hallo, i dont got much experience with the floating paraphase and is therefore asking for suggestions about how to insert a semi hf boost ( somewhat a presence. ) and a resonance like SLO or such?
Or if there is anything in between that would work with that version of floating paraphase with ampeg v4 values.
Ive added a simple sketch of how the stage that nfb is taken from looks like and ideas i had how to make it, but worried it would also alter gain and overall tone to much?
Ie the 1uF + 1k variable resistor, which i suppose would act more as some sort of mid boost than hf boost, maybe easiest way would be to just switch in a 0.1uF cap in that position on/off for a hf boost?
Or these may be horrible ideas of how to best add a presence / resonance?
Any ideas or other circuits to look like would be appreciated!
(Realised resonance pot is slightly wrong drawn, but i believe people understand the intent. )

Am i asking a stupid question or am i just bad at searching within the forum? Tried to find answers with the search engine but couldnt find anything particular.
But if anyone knows a old thread id appreciate to see!
Attatched another picture also showing full phase inverter, along with my two ideas to add some sort of HF boost, and resonance. But not sure about them. :/
