Power Supplies and Daisy Chains

[the recluse]

I searched this topic and found some related discussions, but nothing to specifically answer this. 

I currently have a Boss PSA 120 which I use to power a Boss TU-2, and use the Boss Daisy Chain out of the TU-2 to power 6 (soon to be 7) pedals.  My question is, if I were to upgrade to a 1-Spot adapter, would it:

1. Still permit the use of the boss Daisy Chain through the TU-2?

2. Still permit the use of the Boss Daisy chain through the TU-2, as well as the use of the Visual Sound daisy chain (for example, the 1-spot goes to the VS daisy chain, one of the VS daisy plugs goes into the TU-2, the TU-2 goes through the Boss Daisy Chain to other pedals, and the other plugs on the VS daisy chain go to other pedals)?

Is the draw in mAs the only thing that I need to be concerned about, or is there something about these scenarios that I am not considering?

 The one spot will supply(I think) 1.7 amps- more than enough for a big pile of pedals. The main thing to worry about with daisy chaining is if any of the pedals are pos. ground, they will have to have a seperate power supply.

Other than that you're good to go with both questions- it would work fine.

thanks for the reply. So far I haven't built any +ground  pedals.  Seeing as my DIY addiction is becoming full blown, I imagine at some point in the future I will have to figure that out too.

i wouldnt worry about + ground pedals
1 spot sell adaptors for that kind of thing

anyone here use godlyke? the noiseless pedal wall wart

I wouldn't be so sure...     

There have been quite a few threads about pos. ground and power supplies, please do a search and read up before you try it!

with all the 9v daisy chains, each plug's + and - are wired in parallel to all the others, as are the two DC jacks on the back of the TU-2 or also the NS-2 and the red master switch pedal.  So you can hook them up any old which way.  Just like making things from a schematic, it doesn't matter how components are arranged, as long as they're connected electrically at the right points.

Yep. But that just inverts the polarity of the power supply. You can run either all positive ground pedals on a 1Spot (or any other single power supply) or all negative ground pedals. You CANNOT run both negative and positive ground pedals from the same power supply regardless of the power supply - it's the PEDALS which short the power supply; nothing the power supply can do about it. That's why there are isolated power supplies. But you can do the same thing with one supply for all of your positive ground supplies, and a second one for all of your negative ground pedals.

It's an interesting quirk of English that saying that something is "the....whatever" implies without stating that it's the only one which is whatever. That sense of this statement is not true. While a Godlyke may be noiseless in most situations, I'm pretty certain from my experience with some difficult-to-power pedals that it's not noiseless in all situations.

This is not an uninformed opinion.
