I’m stumped. I’ve tried 2 Vox headphone amps and a third Donner Basement headphone amp. None of them work for me.
I’ve tried both jack holes, all settings, different/new ear buds, new batteries (Donner is rechargeable) . . . everything. The most I can get at max. volume is a very faint sound and lots of hiss.
Any suggestions? Might the input jack on my bass be defective? My full size amp works fine.
