I just got my first bass and started playing a little bit. I also got an amplug2 to play with headphones, but it has a very noticeable hiss. It’s also a bit clunky and when I play sitting on my sofa (hey, gotta practice where inspiration strikes!), the volume control rubs against the fabric and gets turned down fairly frequently.
So I figured I’d just plug my headphones (Grado Sr225i, 30Ω I believe) straight into the bass (Yamaha TRBX304). At max volume, I can hear it reasonably well in the Flat setting, and fairly well at the Solo setting. It’s all rather quiet, but good enough in a quiet room. Best of all, no more hiss!
Are there any concerns with doing that? I know it’s technically just a preamp in the bass, but I don’t think these headphones can draw a lot of power. And I figure any recent opamp should easily be able to drive these mid-impedance headphones without bursting into flames.
