The reasons for giving a circuit more voltage is supposed to be to give the signal path more clean headroom. Also polarity is important. Daisy Chaining and Signal Noise I have a isolated power supply that has a slot that switches from 12v-18v but do not have any need for it. Can't seem to find an original/official schematic online. A real audio amplifier that is designed to preserve the integrity of the waveform, have low signal to noise, cross-talk (if applicable - e.g. It's not as simple as looking and seeing the capacitor ratings in some cases. With that in mind, I am still concerned about the latest recommendation. I don't want to build anything I would rather purchase a cable ready made. it depends you have lot going on. None of the pedals I have on the board right now can run at 18V, so I'm looking for options. 99. Tip: Use a voltage doubler to convert a 9-volt or 12-volt power output for use with 18-volt or 24-volt guitar pedals. Press question mark to learn the rest of the keyboard shortcuts, http://s1022.photobucket.com/user/Angelos7/media/ZW44MODS.jpg.html. Fortunately, most analog pedals are designed with plenty of extra room for higher voltages and they work fine with 18v supplies. CDN$ 69.99 CDN$ 69. What's up everyone. I don't need another drive or fuzz pedal. This is my first post. Pedal Power and Tone. Output Voltages. I don't understand the internal workings on an effect pedal, but I'd imagine it would be easy to repair. The Dunlop DC Brick has two 18-volt outputs. The resistor will use 1/3 watt of power and could burn up (Ohm's law). The only way to really know for certain is to look at the schematic, check the datasheets for the parts, analyze the circuit, and do some simple math. Running pedals at 18v vs 9v, what's the difference? Read honest and unbiased product reviews from our users. An unregulated adapter can give up to 50% more at light load; I'd imagine that the pedal doesn't draw that much current. by using of daisy chain adaptor). Ditto, hence my tagging of the OP and suggestion of contacting Voodoo Lab. Pedals designed for distortion may not sound better at 18V even if they can take it. There is more complete technical advice in other comments here but just anecdotally I can tell you that I have tried using 12v and 18v AC and DC on pedals which recommend 9v DC with mixed results. Some of the Voodoo Lab Pedal Power series such as the Pedal Power ISO-5 have a dedicated 18-volt output. 18V and 24V pedals can be powered by combining outputs with an optional voltage doubler cable. There’s actually quite a few, for 18V maybe start with Catalinbread, it seems as though most of their pedals are capable of running at either 9 or 18V. If you use a Y cable to power two pedals from a 18v outlet, each pedal will see 18v. But that doesn't mean it is safe on all analog pedals. I know theres alot that can change a 9v into the 18v it needs and theres also plenty that its not recommended to do it, but what are some of the diamonds in the rough that sound really cool running at 18v? It’s said that with using an 18 volt power supply, it’s supposed to give you more headroom and a little bit more open sound and clarity. using a normal 2.1mm power cable to connect from the power supply to the singular end of that cable, then connecting each of the dual ends to a pedal) should split the voltage rather than doubling it. Swapped and all were fine, but it's definitely not going to work for you. Likewise, if the pedal uses, say, a 1k ohm 1/4 watt resistor that will see the entire 18 volts, you can't use an 18 volt supply. Learned that the hard way. You need 9V for the HX Stomp not 18V or 24 V. Some 9V pedal power supplies offer multiple isolated outs with 500mA max each. The adapter you suggested doubles the voltage (by connecting two voltage source in series). In most cases there will be a noticeable difference in the tone – sometimes quite subtle, at other times more obvious. The circuit will not be "smart" enough to divide that 18V by four as required, it'll divide it by two, you end up sending 9V into your IC and you blow it up, rendering the pedal useless. you can under power a pedal and it shouldt cause any harm think about it. You would need to observe the actual schematic of the circuit, understand what voltages parts require, or can't accept and then judge from there. So ability to convert 18v to 9v gives me more 9v outputs, simple as that. With this FX Power Source kit, you can build a powerful power supply for a pedalboard with up to 8 pedals 9V, 2x 12V and 2x 18V! I power my board with a 1Spot CS7, and the only spot left is for an 18V pedal. DP-3 includes two high current outputs, capable of properly powering high power effects such as Boss Twin, Line 6 Modelers, and TC Electronic Nova pedals. They're designed around a 9V power source; that they can be run … JavaScript is disabled. But, it doesn’t let you connect pedals with different voltages. Some IC's and transistors are specifically set to run somewhere between ~3.5-5V, which means some circuits make a simple passive voltage divider and run it at 4.5V. The Vangoa Guitar Pedal Power Supply, 10 DC Output Pedal Board Power with USB Port is a slim 2x6 (approx) isolated power supply that comes with enough 2’ power adapters for all 10 outputs, along with a couple of pigtail adapters for any reverse polarity pedals you may have, along with its own 18v power … So you have to take it on a pedal by pedal basis. Some pedals like the Fulltone OCD are rated from 9v to all the way up to 18V which in this case, yes you can use a 12v this adapter because the pedal is capable of handling that much voltage. Find helpful customer reviews and review ratings for Tom'sline Engineering Pedals Power Supply - 9 Pedal Power Isolated 9V/12V/18V 100mA/1A Outputs for Effect Pedal at Amazon.com. I use them all at 9V. My question now is regarding pedal power. Don't use that. JOYO JP-02 Guitar Pedal Power Supply Pedal Board Guitar Power Supply with DC 18V Pedal Power Adapter & 9V 100mA 500mA Isolated DC Output for 9V 12V 18V Effect Pedals. For most analog dirt pedals 12v should be ok. A lot of unregulated 9v DC power supplies can put out 12v anyways. Most effects pedals use 9V batteries, and almost all power supplies will output 9V power. Voltage is only one part of the picture and even if you get the voltage right, it's possible for a power supply to ruin your pedal. You could build it into a 1590a to have an (almost) 18 volt power supply, or build it into a pedal with a switch to toggle between 9v and 18v supply. I see no mention of a voltage change. -. That means it could have been fed 18V. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. I still need to try the two brick option. If you have a pedal that needs 12 or 18V, you would need to get another power supply that will work with that voltage to power your pedals with that requirement. Are you suggesting that plugged it into an 18v PSU, two outputs will be 9v? I know its kinda lazy and I'm asking for a lot of hand-holding but would anyone be able to tell me whether my Wylde Overdrive would be happy running at 18v? Does anyone have any suggestions? There’s actually quite a few, for 18V maybe start with Catalinbread, it seems as though most of their pedals are capable of running at either 9 or 18V. For 12V I would look at some of the older T-Rex pedals, most of them ran at 12V and they look/sound great, have top mounted jacks and can be picked up at a much lower cost than when they first came out.
