EHX Bass Blogger power issue

johnnyseven · Post by **johnnyseven** » Fri Jan 06, 2012 11:46 am

The bass player in my band has an EHX Bass Blogger. He powers his pedals with a One Spot and daisy chain but this pedal doesnâ€™t work when being powered by the daisy chain, however it works fine when being powered on its own with a power supply. He asked me the reason for this, I said that it is just that some pedals donâ€™t like to be daisy chained. He also wants to know a way round it, any ideas? Is the solution to just use a single power supply for this one pedal or could he get a power supply with individual/isolated power outputs. If this is the case can anyone recommend one that he can get in the UK for a reasonable (cheap) price?

It's about current consumption, the power supply he's using has to supply at least the total mA he is drawing. I suspect he's not got a power enough supply or he has too many pedals.

Isolated outputs aren't necessary, it's not centre positive it looks like it's centre negative (standard)

The manual does actually say it'll only work when on its own power supply, due to the design I guess. These guys reckon it'll work okay with pedal power with isolated outputs: http://www.talkbass.com/forum/f36/ehx-b ... -a-450728/

I also just read that the Virtual Battery will solve the problem (allowing your bassist to run it from his daisychain), but they're like 30 quid.

Maybe just pick up another Johnny Shredfreak PSU to use for the EHX? While probably more than he'd like to spend, it'll be a handy backup to his current daisychainin' PSU and we know they're not noisy or owt. Picking up a 5 quid adaptor from Ebay often results in some nasty noise problems when used with something audio-based like this.

Or just pick up the EHX unit? "The optional 9V power supply from Electro-Harmonix is 9.6DC-200BI (same as used by Boss(tm) & Ibanez(tm)) 9.6 Volts DC 200mA. "

Thanks chaps. I'll pass the info and point out the he should have read the manual.

I think I read somewhere that my Microsynth doesn't work on a daisy chain either so I've always had it on its own power supply. So I think there are a few older-design EHX pedals like this, and even the ones that have been updated to the new boxes keep the issue as the actual guts of the pedals aren't really changed at all.
