Can I use my pedal board power supply?

The Pro Guitar pedal comes with a 9 volt power supply, but was designed to be used with any pedal board power supply. It is recommended people using the Standard pedal, and Low Profile pedal, use the 24 volt power supply that comes with these pedals. http://www.salvagecustom.com/shop/pedalboard-riser

MY MXR STEREO CHORUS LED LIGHT START TO FADE AFTER CONNECT WITH DC BRICK! DOES THIS MEAN MY PEDAL WILL HAVING ANY DEFECT?


I don't know what you mean by "DC Brick"...

The MXR Stereo Chorus unit requires a special 18 Volt power adapter. The common 9 volt pedal power adapters will NOT work with this device. If you have batteries in the unit, when you plug in an incorrect adapter, the unit disconnects from the batteries and the caps discharge so the light will fade.

You will need to use: ECB-004 18-volt AC Adapter Best to use the manufacture's exact device for this one.

My boss MT-2 plays is extremely quiet when turned on, the clean channel comes through great, as soon as i turn it on its hardly audible, using the boss power supply, with correct ins and outs, and tested the cables, any ideas?


It is possible the pedal is DESIGNED to be used with an amplified (preamp within guitar) and yours MAY be a passive guitar. You did not tell us what guitar you have.
Many of the processors for guitars depend on having a "line level" signal and that requires that your guitar has a built in preamp.
If your guitar doesn't have a preamp in it, buy a preamp to put ahead of this pedal.

I have 8 outputs on my Furman SPB-8 power supply for 9 volt guitar pedals. I moved the power supply to a bigger pedal board, drilled a few holes to anchor it it to the board. Now none of the 9 volt outlets work. Everything else works (all of the 110 plugs). Since this is an older unit with expired warranty, I took it apart. I can't see anything obvious, but I did see a donut shaped part ...looks like it may be a 110 volt to 9 volt converter. Got any clues? Thanks, MIke mikespi8@sbcglobal.net


How are you at soldering? Do you have a voltmeter? Is there a fuse in the unit? Did you make sure no metal chips from drilling shorted anything out? The donut shaped part could be a transformer, or it could part of a filter. To get DC for the pedals, there are usually these components: a transformer (to decrease the line voltage), a rectifier bridge (turns AC to DC), a filter capacitor (to get rid of AC ripple from the rectified AC) and a voltage regulator (futher reduces ripple to eliminate hum). The filter capacitor is usually the most likely component to fail. The manual states that the maximum current draw for any pedal is 100mA. It also states that their is an 'electronic fuse, called a PTC (probably a positive temperature coefficient device. From what I've found, it uses 7809 regulator, which is one of the key components. I found a page about building an effects regulator. In the picture, the regulator is the little black square device towards the right. There is a metal tab, that should really be mounted to a heat sink. I'm including a link to the page for designing this supply. They're pretty simple, and I can find you the parts pretty cheap, if you you want to try building one. Another possibility is to find a prebuilt supply that would fit inside your case. You can get a schematic from furman if you have the serial number. In the picture the big 'can' is one of the devices I'd suspect. See if it's bulging on the end. Anywa, here's the likely culprits: the biggest capacitor (big can, voltage regulator, ptc. The ptc is probably square or rectangular, and rather small, probably about the size of the regulator, but thinner, and maybe tan or yellow, but could be some other color. Before you try any repair, if you have a voltmeter see what happens with no pedals. Then if you can read 9 volts, try the pedal with the lowest draw. The current draw will be listed on the pedal near the power supply plug. If that doesn't work, Check the voltage on the ouput pin of the regulator. It should be on the right, viewed from the front. I'm including a link to a page with a 7809 that shows the pins. There are several different versionsa I think, with different current ratings. Anything over 1 amp should have the metal tab mounted to a heat sink. The fixya format is not so conducive to solving this. You can go to ecurrencyparadise.com, and click the email me link to contact me. I'm a BSEET who has been playing with this stuff for years. There's plenty of ways to get this working, probably even better than the way they designed it.

my effects on the behringer djx 700 dj mixer stop working how


This is a wild educated guess.

I repaired a Behringer guitar amp that had a DSP effects in it (BX1200 I believe).

The effects were on a seperate board and the board had its own 5 volt power supply. The filter capacitor for the 5 volt power on the board was UNDERSIZED and it had degraded causing the 5 volts to drop out of regulation, dipping to 4 volts. This caused the DSP effects to fail.

YOUR device MAY use the same DSP OR design.

Check the 5 volt power with an OSCILLOSCOPE to look for dips below the 5 volt operating point that occur at 120 HZ.
