Replacing 2 x 9 volt battery with power supply

[frannie01]

Hi I’ve just got hold of a dean pace Eub and noticed that the battery life isn’t great.Is there anyway to replace the batteries 2 x 9 volt with a power supply or is it a case of modding the piezo bridge some how 

 

thanks 🙏🏽

It's not easy to do - 18V needs 5 x lithium cells which is awkward.

 

A better bet are rechargeable 9V batteries   - EBL USB Rechargeable 9V Batteries - 5400mWh Long Lasting Batteries with Micro Charging Cable 

or bulk buy 9V ProCells

 

If you could tolerate a DC cable you could use a clean 18VDC supply (MeanWell are good) for practicing.

If you keep the bass plugged while not playing, the batteries will die quickly. Piezo buffers need very little energy - wondering is there a leak somewhere?

Ok Thanks it was an issue that came up on a forum and the batteries were pretty much fried when I got the instrument .I had a sire that needed 18volts and never had an issue.

 

I’ve actually clipped on a condenser (running it through a pre for the phantom power) now and that sounds much more “acousticy” and will only drain the battery if I blend the piezo and the mic

Hi yeah I’ve been looking at the rechargeables online.The output from the Dean is very low and required a buffer preamp.In the course of experimentation I also tried adding  a condenser mic which was a revelation.

 

It sounds good now and no worries about draining batteries unless I blend in both the piezo and the condenser.

 

might still research that charging cable though can’t hurt can it 

 

Thanks for the info 👍🏽
