I did a search through the Bass Buddy threads for this topic, but really did not find any specific suggestions. I really dig this little unit for learning tunes, straight from my computer. The headphones I have been using it with are ok, but they seem to have a " fuzzy " sort of after effect as I'm playing along. I've reduced the bass on the EQ to almost nil, with a little bump at 160 hz, everything else is flat. The headphones I am using are Sennheiser PX100-ll , and some Audio- Technica ATH-M30 phones. Both seem to have this effect. The manual suggests using headphones with a 16 - 60 ohm impedance, which, IIRC, the Sennheisers fall, not sure about the AT's. Is this just some effect of using headphones with the Bass Buddy, or do I need different phones ? I've tried different EQ settings, but the effect is still there. Listening to pre recorded music through the BB does not have this effect in both sets of phones until I start playing along. I switched to the Active input, thinking my Jazz might be a little hot, but then I fid myself having to turn up to hear myself playing along. Any suggestions, advice, etc. , welcome.
