pedalboard not working

[hose-902----]

alright ladies and gents, here's a stumper for you. I've got 11 pedals on a pedalboard, with the Ciocolate Bar power supply powering them all. It's been working like a champ. Plugging into Fender Blues Deluxe RI. Anyhoo, I got a couple of new pedals. I swapped my chorus pedal out for the Choka pedal by TC Electronic. It worked great on its own and with the other pedals. I went through and turned each on on individually to see how they played together. Now tonight my other new pedal arrives, the Lenny from JRocket Audio. I replaced the tuner in the chain, made sure it was enough power coming to this pedal, and.... nothing. All of the pedals light up, along with the power supply, but no sound at all. I fiddle with the volume, no dice. I max volume on guitar, and on amp, nothing. I had a moment of panic and checked, but I had already come out of standby mode on the amp. What gives? I'm getting the usual small amount of hum that increases, decreased when I manipulate the pedal controls.

I thought maybe the chain hates the Lenny, so I take it out of the loop an put everything back as it was, still nothing. I can however go from guitar to Lenny to amp with no problems. What could be the problem here?

Loose connection from the jostling of the pedals, relevant video below. If the hum is changing with the knob adjustments, then the issue has to be before that.

Are they isolated power outputs? Also how much power draw are you getting? Redo the maths as I suspect you've hit the limit for that power supply.

no this isn't it, but funny I definitely checked as I've done that before.

I'm not techy enough. Here's the exact power supply. I'm powering each pedal with 9v. Also, if this was it, why would it still be screwed when I undid it back to the way it was before?

It's the amp draw that's the issue. Many power supplies tap out at 2A (2000mA). It should by written on the supply somewhere what the output A is. With 11 pedals, you'll be hitting 1A maybe 1.5A if you have many digital pedals.

It's one of the selling points for all the Gig Rig power supplies by being the only one that sells a 5A supply which I have yet to max out.

The simplest explanations are going to be either wanting more current than your power supply can provide, or (and this seems more likely if you've already put things back as they were) a connection having been disturbed when moving things around.

For the latter, I'd take a divide-and-conquer approach - pick a pedal in the middle of your signal chain, disconnect the patch cable from the input and plug your guitar cable in there. If you're getting sound now, the problem is before that; if not, it's after that (of course, this assumes that you only have one problem ). Then you pick the mid-point between where you are and which side the problem is in and repeat the procedure (any computer scientists will recognise this as a binary search, but that's not important right now). That's probably the most efficient way to find the (most likely cause of the) problem.
