External Pre Amp AC Adapter?

[bigRalph]

I have one of the earlier Sadowsky external pre-amps which I enjoy using with my passive, non-Sadowksy basses.  Feeding it batteries gets old after a while. I have tried using various AC Adapters with it - all of them within the range of specification for a 9V battery replacement - and all introduce a loud hum.  Any suggestions?

Have you tried the AC adaptors we sell?   Even with our Sadowsky approved adaptors, in noise sensitive situation, we recommend battery.  But our AC adaptors in general are quiet.   Our pedal requires a linear regulated power supply.

The latest one I tried is the BOSS ac adapter that works with all their pedals and has the exact same specs as yours.

If I buy yours and it still hums can I return it?


Thanks
