hi guys, i own an Ibanez DE-7 Delay Echo Pedal.... it works great, but i have a little problem, when i power it up with the adapter set to 9v the pedal doesn't work.... when i activate it the led just lights briefly and then is off and no sound comes from it
but if i set the adapter to any value below 9v (even 4.5v) the pedals works correctly..... what could it be??? i don't think it's an adapter problem, cause i use it with other similar ibanez tone-lok pedals and it works good set at 9v :shock:
have you used a volt meter and measured the actual output voltage comign from the 9v selection...
i had one when i was a teenager that did something similar and come to find out it was really cookin at the 9v level. like 15v or something..
you mean to measure the voltage coming out of the adapter? yep i could do that... but it actually works with the other pedals
Quotebut it actually works with the other pedals
that really doesn't tell you much. The DE-7 may have some kind of current limiting or over voltage protection.
Try a REGULATED 9V supply. Chances are that the 9V setting is giving you much more than 9V.
Does it work with a battery? Do you have the battery in the pedal while you're using the adapter? Just thoughts I had...a current limiting function in there could certainly cause something annoying to happen. Sometimes these 9V adapters aren't very accurate. I've had some from 10 to 12 and sometimes 14V. I had a 12V wallwart that measured 24 V open circuit and didn't get very close to 12 until it was sourcing its rated current. They are usually designed for a specific load as they aren't regulated supplies.
That's an interesting problem It would be interesting to track down a schematic for one of those.
