Pedal board power supply for HX Stomp

Recommended Posts

I'm starting to put together a list of what I will need to build a small pedal board, and I'm getting conflicting info online and from a local guitar store about what options there are for powering the HX Stomp.  Ideally I'd like to use something like the Strymon Ojai or similar, but it looks like this is not possible without a bunch of adaptors and a way to reverse the polarity.  Is this still true, or is there something I'm missing that's changed recently?

 

It'll be a small board, though all the pedals are higher power draw units.  Basically the Stomp, Volante, and maybe the Timeline as well.  Ideas?

Hi,

 

indeed it is a real shame what Line 6 did in terms of power connectivity especially for the stomp that is made to live on a pedalboard with other pedals. Different Polarity, different connector. For what? And then in addition they managed to build the worst power adapter I‘ve ever seen.... Just buy a Truetone  1Spot CS6. It works perfectly.

 

Regards Marco

Thanks Marco.  I'll look into that one some more.

 

Next research project, low profile right angle midi connectors :)

Thanks Marco.  I'll look into that one some more, but do you know if it comes with the proper cables too?  I saw it has a polarity reverse, but I didn't notice the HX used a different connector too.

The Stomp is center negative, just like the vast majority of pedals out there. The reason so many solutions require a polarity swap is because the 3rd party L6 cable adaptors (to bring the size down to standard) were designed for older L6 tech that was center positive and also reversed polarity. So if you're using the L6 adaptor you have to use a polarity reverse cable to bring it BACK to center negative.

 

With that said the Truetones are great. I own the 12. Both the 6 and the 12 come with all the cables.

Does the truespot supply sufficient amperage? The back of the hx stomp calls for 3a (3000ma) but the truespot cs6 specs top out at 1600ma.

 

I have the 1spot daisy chain 9v supply I use today for a DI and a wireless receiver, but I just picked up an stomp to add to my portable rig. I don't know if I even have the converter plugs any more so I will probably have to order something new regardless, but my portable case only has so much space... Part of why I decided to go the stomp rout was space consolidation.

The Stomp draws around 1.0mA +/-. The DC-3g power adapter that comes with the Stomp is rated at 3A, but that's just its capacity. So the CS6 will power the Stomp, but it depends on what else you have connected to it.

Thanks. Yeah I figured it would be similar to other multi-pedal setups, as long as the total output is +20% above combined consumption levels, I should be fine. The 3A on the back of the stomp got me concerned tho. My relay g70 wireless receiver draws 500ma, so I'm guessing technically I will be ok with the 1spot 9v, but I'm approaching max capacity. 

 

Should I be concerned at all from a warranty / performance perspective running the stomp on a shared power config like that? (assuming I can find the plug converters that came with my 1spot or get another). I too, hate the included power supply.  What was the thought on that configuration?

If a problem resulted in the Stomp that was a direct result of the power supply, then yes, it could void the warranty. 

 

Now, to be clear, I use the Truetone CS12, so I've decided to take the risk and I'm glad I did so far, but yes, it is still something to think about.

Am I going to need to daisy chain the CYR AND the CL6 adapters together off of the truetone?

I use the TrueTone CS6 to power my HX FX and 3 other pedals and it works great without any current doubling, etc. As others have said, you just need to use the included L6 converter and the polarity converter to switch it back. A little bit of a hassle, but my board is neat and tidy now. On a Pedaltrain Metro 20 I have a TC Polytune, VFE Standout, EHX Soul Food, and the HX FX. Loving the portability.

To the best of my knowledge, because of the scribble strips and additional LEDs, the FX actually draws more current than the Stomp. But yeah, the L6 adapter reverses polarity for old L6 devices, so the polarity plug reverses it back to 'normal'. That's the only "downside." You may be able to find a third party plug, but the Truetone comes with everything in the box. I reduced the size of my board from a PT-1 to the Metro and got rid of a bunch of short extension cords and power strips that I needed to deal with multiple wallwarts/PSUs. New rig is clean.

yeah, I remember unpacking my 1spot and because I didn't need them at the time the rando adapters got thrown in one of my 'cable hell' crates. My penalty for not being psychic and or having a better filing system :D I'm positive I will find them the day after I receive the replacements I'm ordering. At least they aren't terribly expensive.

Well, at some point I got my truespot model #s mixed up. I was talking about running the HX stomp off of the just regular truetone 9v, (not the CS6). With the adapters, it is able to run the stomp and the G70 relay, but there is some light grounding hum (90hz-230hz). Enough that it registers intermittently on the stomp's tuner. It's pretty low volume and probably won't be noticed in a show because I can gain up the input signal and I set the input to line instead of inst (does that reduce dynamic range?) but it's a no go for recording so I guess i'm going to have to scale up from a daisy chain power supply, unless anyone else here has any ideas. :-/

I purchased a Truetone 12 to power the Stomp as well as the G10 relay (modified) and two other pedals.   For those who use this set up, I wanted to clarify the power out put.  I have read that the Truetone's will put out more mA than the output that is labeled on the output plug, as long as you don't come close to total max rating of the power supply.  The Stomp is essentially right at 850/875 mA.  Did you use a current doubling or current splitting cable (that doesn't come with the package) or did you just use the Line 6 adapter into the polarity reversal and into the 800mA output.  

 

Also, would you recommend a current splitter adapter for a 350mA pedal or just plug it straight into the 300 mA outpu?

The TrueTones have the big advantage of being as switching power supply, meaning there are no fixed transformers for an output but electronics that supply what is actually needed.

Its  capable of releasing all the current to one port, hence ther is no need for any doubling y-cabeling whatsoever.

Thats how ist should be...

 

stupid Line6 polarity must be dealt with the supplied adapter, though

Do NOT use the 800mA port. That is for AC power and you risk frying your Stomp, or at least giving it some nasty hiccups.

 

All you need is one port (the 500), the L6 adaptor, and the polarity reversal cable, and you're set. Works great.

 

(Also, yes, it can output much more than the port states, so 300 works fine for 350 - as long as your total pedals don't go over the grand total possible).

I'm using the Cioks DC7.  They recommend two adapter cables (that aren't expensive) to combine two outputs and then convert to the right size plug. It works great and is very quiet.  I power my G10S, tuner, Drop, wah, 18v flanger and phaser.  The DC7 comes with plenty of cable and they have a chart to help find if you need specific adapters.

I ended up getting a custom power supply for my mini-board, with a dedicated 1.5a output for the stomp, and two other .5a outputs, all isolated, and in a custom compact case 2x4x1" from sweetfootpedals dot com via reverb.The guy there totally gets it, and has a bunch of line6 PS stuff, including a PS with external stomp switches built in!

I went with the Cioks DC-7 which has 7 outputs each capable of 0.66 mA at 9V.  I combined two outputs for an HX Stomp, two outputs for an HX Effects, one output for G50 wireless, one output for a Zoom MS-60B in an effect loop off the HX effects, and one output for a Boss TU-3 tuner.  Could certainly daisy chain more off the tuner to add anything else.  Sweetwater had the cables to combine the two outputs to double the current, and the larger "yellow end" cables to get to the 2.5mm pin on both the Stomp and Effects without having to do anything about polarity changes.

Hi all

 

I can confirm that the palmer PWT 12 MK2 works with the HX stomp

 

https://www.palmer-germany.com/en/products/power-supplies-chargers/18553/pwt-12-mk-2

 

This psu is quite small and relatively cheap (And is dead silent! good job palmer!).

 

The only issue is that is a bit tricky to set the right output voltage with the small pot, so you have two options:

  1. with a multimeter carefully set the same voltage (I put it at 9.4V) on two of the 500ma outputs) and then connect the hx stomp to two of the 500ma outputs
  2. or use a 5 pedal chain (like this) and connect 4 of the 9V 300ma output to get 1200mA (yes they are well isolated) (and you still have the 4 500ma variable output for something else)

Just remember that this psu can source maximum 2000ma in total so the hx stomp is ~1000mA -> another 1000mA of pedals

 

Of course neither me not line6 is supporting officially all of this so... use at your risk

 

Cheers

Nick

I have had that issue with those inexpensive Truetone power supplies before myself. Strangely enough was also when using a wireless unit with it although not a G70. Eventually just opted for another inexpensive Ibanez power supply I had laying around which didn't cause an issue. Those Truetone ISpots are not isolated power obviously when daisy-chained and even when used with only one device can be quite noisy with certain pedals or wireless units. Other times they play nice with everything and are a good inexpensive solution. Luck of the draw.

Hi - I've just put together a neat little fly-rig using the HX Stomp, a Strymon Sunset, an EP Booster and a Boss expression pedal, all on a Pedaltrain Metro 20. It's all powered by a Truetone 1 Spot Pro CS6 and works a treat! Make sure you attach the CS6 with the supplied screws as Velcro is too deep. It's millimetre perfect. And use the correct adapter cables, all supplied in the 1 Spot box...
