hi. i just had thought. can you please put editable txt file for equalizer for unlimited freqency’s. can some please help me with?
No. I can say with almost 100% certainty this will not be added to the Fuze+. In fact, no further enhancements and likely not any fixes either with be forthcoming for this model. At this point, it is what it is. Rockbox (3rd-party, open source firmware) is available and adds certain benefits and modifications, however I don’t believe what you are asking for is one of them.
TW is right, however, using Rockbox, the equalizer is much more adjustable (I believe) than the OEM, so even if it is not exactly what you are looking for, it may give you enough customization to mostly satisfy your needs. I think it’s worth a try, it won’t cost you anything other than time and it is completely reversible if you decide RB is not for you.
