one spot adapter and phase 45

Ok, here's a strange issue.  I just finished a phase 45.  I love it.  The sound is beautiful and everything it should be.  I went to put it in my pedal chain and hooked it up to the one remaining spot on the daisy chain of a one spot adapter.  There was chaos with the sound.  Ok, i figured maybe there's not enough juice left as the other 4 spots are already being used off that adapter, so i plugged it into a completely different one spot adapter, this time with no daisy chain, just the original natural pin into the pedal's dc jack.  There was no noise this time, however there was a much much more subtle phasing then i had experienced when i first tested the pedal. 

I ended up using an old Zoom adapter that i usually use for testing purposes, and wallah! the phase was returned to it's normal shimmery goodness.  I'm not sure what to make of this as i have the one spot powering several other pedals with no issues.

Well, actually that's not entirely accurate...the reason i'm using two of these in the first place is because my Rangemaster when hooked up to the daisy chain was also over the top noisy and unusable...with just the single one spot and no daisy chain, it sounds great...The other issue is my Space Echo (this is the Boss reissue...RE-20 i believe...beautiful sounds)...i was experiencing a lot of noise with the distortion channel of my amp and just extraneous noise in general...i believe this was from the space echo...as the noise oscillates and is identical to the oscillation of the Space Echo.  I tried the Space Echo with my Zoom adapter as well and the noise disappeared.

Just wondering if anyone else has had any One-Spot issues like this.  I think overall they're a great deal and they save valuable space, but i would like to be able to power everything from one source like this instead of having to use multiple adapters.  Any comments or similar experiences and/or solutions are welcome.  I know R.G. works with Visual Sound, so i would love to hear if you have heard of any issues like this.

Much thanks!!!  ;D

That's bizarre.

I wonder if the daisy chain cord has a bum contact inside. That's about all I can make out from the daisy chain experiment.

We have also found a few cases where digital effects or effects with internal switching power supplies seem to interact with the 1Spot. Sometimes this changes depending on whether there are other effects in parallel. It's almost like the switching effects are forcing power back out at times.

I'd suggest first seeing if your dealer can supply you with another daisy chain cable to eliminate the chain cable issues. I think that may clear up some of this at least.

Thanks R.G. I'll see if i can check a different one out.  One other issue i'm having withthe Phase 45 which has nothing i think to do w the power issues is the popping sound when engaging/disengaging the effect.  I already have a pulldown resistor in the beginning of the circuit.  Would adding one at the end be advantageous?

Thanks again R.G.  I actually figured it out this morning...it was a stray wire on the switch that was pressing onto ground once I put the cover on.  Some electrical tape fixed everything and I'm actually glad it happened as I had never tweaked the trimpot before...now its a very lush phase...
