For bass guitar practice, I'm using a headphone amp - or rather a preamp with a headphone out - which I then put through a small analogue mixer or directly to headphones. I like the sound of this preamp and I can get a few different tones.
There is one issue however, when I'm using fuzz or overdrive I get a bit of high-pitched whine - which is quite noticeable with headphones (even if I turn down the treble).
Is there a way to get rid of this high pitched noise?
I was thinking some sort of "analogue low pass filter" for headphones - but I couldn't find many of these. I could get an analogue EQ.. but it feels like overkill and they tend to be quite big. If I were using a real amp I could use an EQ pedal... but presumably the don't work that well for headphone rather instrument signal levels.
Perhaps an EQ before would work as well if the noise is coming from the guitar and gettling amplified. Is this likely to work (so that I should buy a pedal to test it out). Also I guess there might just be a noise source...
