Pedal powering conundrum

[Sibob]

FWIW, I’ve settled on a modified Gigrig workflow with success. Generator into a Mooer 2-way splitter, into 2x Isolators. Being conscious of separating the Tuner from the other high~draw pedals was the only consideration here…bearing in mind though that ‘high-draw’ in this context means 40mA for the Linden, 50mA for the Chorus, and 100mA for the tuner, everything else sat between about 6-20 mA.

Sorry I’m late to the party, I’d have asked if the EBS Runsten is suitable, I’ve one sat here I’m about to review and it promises much. I think it might even power the Quad Cortex using doubler cables and the like.

I was wrong about this. I had powered up the Stomp successfully so I assumed it was working, as on previous occasions when it had insufficient power it went into a startup loop, flashing up the splash screen then shutting down and restarting. This time, it went all the way through and responded to button presses, and to HX Edit. However, I hadn't been putting a signal through it. When I did, although it kept showing on the screen and responding to HX Edit, it neither made a noise nor responded on the tuner. Switching to the standard power supply, it did work. I can't find my current sharing lead so I've ordered a 5.5/2.1 to 5.5/2.5 adaptor and I'll use a daisy chain lead to current share, and see if that encourages it into life.

 

Edit: just to emphasise that the Stomp is a massive current drain. Very few pedals will require that sort of power. Don't be discouraged from using this for a "normal" pedalboard.

 

So, further to this experiment - using a splitter to current share didn't work. However, I used one of these:

with the output set to 9V (move the jumper from 12V to 9V). Works with variable voltage USB-C supplies. Connected it to the power bank. Using a 5.5/2.1 DC plug, connected + to the power outer and - to the power inner (important, that bit), checked I was getting 9V and the right polarity, then connected this to a daisy chain, using a 5.5/2.1 to 5.5/2.5 right-angle adaptor to connect it to the Stomp and also connected up an EHX C9 organ synth and a Line 6 G50 receiver. It all worked, which was nice.

 

So, in conclusion: the AliExpress power supply works for the average low or mid powered pedal but just about runs out of puff for the extremely thirsty ones. The USB decoy board set to 9V works for high drain devices and can be used for multiple devices by daisy chaining as long as they don't need isolated supplies.

The EBS looks maybe twice as big as I had space for, luckily the Gigrig stuff has nailed it!

Hey mate,

In the meantime, I’ve had it confirmed that with accessory cables, Runsten can power the Neural DSP Quad Cortex, for those who need high current outputs.
