Members denimboy Posted May 28, 2008 Members Share Posted May 28, 2008 I get this feedback sounding noise from the Holy Grail when it's in my chain. Problem appears when its OFF (which should be TB). I have double-checked the power supply and made sure nothing is broken or short inside. I't surface mount soldering with micro-components on PCB so I can't do much. Any Solutions? I'll probably just put a TB switcher on it to skip the noise.. But if possible I'd fix it . Link to comment Share on other sites More sharing options...
Members greenweenie Posted May 28, 2008 Members Share Posted May 28, 2008 How are you feeding power into it? Link to comment Share on other sites More sharing options...

Members rileykill Posted May 28, 2008 Members Share Posted May 28, 2008 Try the EHX power supply ... the Brick isn't isolated. Link to comment Share on other sites More sharing options...
Members denimboy Posted May 28, 2008 Author Members Share Posted May 28, 2008 I don't have it. I bought the pedal alone. Link to comment Share on other sites More sharing options...
Members greenweenie Posted May 28, 2008 Members Share Posted May 28, 2008 They should come as a set because bnew its a set with the adaptor. I had that same problem when I powered my Holy Grail with my Pedal Power 2 clone but it went away with the adaptor. Link to comment Share on other sites More sharing options...
Members chisa Posted May 28, 2008 Members Share Posted May 28, 2008 yep, needs its own adapter, it is very power hungry, Link to comment Share on other sites More sharing options...
Members Philly Fuzz Posted May 28, 2008 Members Share Posted May 28, 2008 I don't have it. I bought the pedal alone. Do you all mean the EHX "AC/DC Adaptor" that plugs into an outlet (and the pedal of course)? If so, I just happened to find one in my desk that was from my Small Clone which I sold (apparently without the adpator, lol!). You can have it, if you want.

Members itkindaworks Posted May 28, 2008 Members Share Posted May 28, 2008 I had the same problem trying to power it with a godlyke power supply. They certainly are power hungry. Link to comment Share on other sites More sharing options...
Members toneforhire Posted May 28, 2008 Members Share Posted May 28, 2008 I solved my eh holy grail hiss problem by taking it back and exchanging it for a boss rv-5...sounds better without the noise... Link to comment Share on other sites More sharing options...

You can have it, if you want. Take him up on this immediately. The Holy Grail sounds awesome and works fine w/ the power supply that ships with it.

Members fuzzylogic220 Posted May 28, 2008 Members Share Posted May 28, 2008 yeah, as long as you power it seperate from your other pedals then the hum will go away. i just use a onspot for it . and then a one spot for all my other pedals and it works great.

Members Saturnine10 Posted May 28, 2008 Members Share Posted May 28, 2008 I have my HG powered from my 1 spot as well, but its in the daisy chain with all my other pedals, seems to work fine.. No sound issues at all.. Link to comment Share on other sites More sharing options...
Members Rogueweez Posted May 28, 2008 Members Share Posted May 28, 2008 My HG worked fine off of my 1 spot for about a month, then started up with the high pitched whine. Put it on an old DOD power supply and solved the problem. I have the original power supply, but the DOD was handy at the moment. Link to comment Share on other sites More sharing options...

You can have it, if you want. the holy grail needs one which can put out 500 mA - one for a small stone probably won't get within 400 of that. BTW i had a hum on my amp tonight, just out of interest i unplugged the grail - you guessed it, it went, noisy bastard pedal - needs to be in a socket on its own - only for recording, live the hum i was getting was nothing to bother you.

The Grail only wants 235mA. So 400 mA is more than enough but you're right, getting the 500mA HG adaptor is the way to go. More mA=less chance of shorting Link to comment Share on other sites More sharing options...

You can have it, if you want.If it's the US9DC-100, it won't work - the Holy Grail needs a more powerful unit. Like mentioned above, the HG uses about 225mA, and the OE adapter (US9DC-500) is 500mA. /Andreas Link to comment Share on other sites More sharing options...
