Pedalboard

[Brenkoh]

Hey ppl , a lil problem over here.

AMP>biyang ch-7 chorus pedal>delay pedal>sansamp gt-2>ibanez ts-7 > vox wah > guitar.

I have an adaptor thats only meant for one pedal and connected it to a daisy chain. Everytime I on my sansampgt-2 or the chorus pedal , there would be a noisy humming sound. If I just buy a onespot, will the hum sound be gone?

 

[niteblade]

probably...

Your adapter may have grounding issues.. I use the voodoo lab pedal power 2 plus and its great..

If thats a little to expensive, IMO a great/cheap power supply is the T rex fuel tank/ fuel tank Jr.. Get it from Davis..

Just a sidetrack if i were you I'd place my delay at the end.

 

[Brenkoh]

hmm, alright.
err isn't wah suppose to be last?

 

[Whitestrat]

oh? your chorus is AFTER your delay pedal? that's interesting...

Wah is usually first in the chain.

What you listed:

AMP>biyang ch-7 chorus pedal>delay pedal>sansamp gt-2>ibanez ts-7 > vox wah > guitar.

...is actually denoted erronously. While that visually represents your chain of effects when laid out on the floor, the actual signal flow should be in the opposite direction. in other words it shoud be:

guitar -> vox wah -> [chain of other effects] -> amp

Just to prevent further miscommunication.

BTW, a one spot might not cure your noise problems. You can try though. Preferably you'd need an isolated power supply, and as far as possible connect each pedal's power input to a dedicated power outlet of the power supply (avoid daisy chaining as far as possible). Some pedals don't share well with others, leading to noise.

I've troubleshoot and found out that My sansamp gt-2 can't share power supply with my randolf-modded ibanez ts-7. When I unplug ibanez ts-7 from the daisy chain, there is no noise at all when I turn on my sansamp gt-2. I don't know if I should get the T-rex power supply from davis or a onespot. My prediction is the pedals have different voltage and not all are suitable for a 9V adaptor? I can't see the back of the ts-7 pedal cause it's velcroed.

I had a OneSpot powering a few pedals via daisy-chain into a ToneLab LE (i.e. a few different powersources) and there was a hum like you mentioned.. so I sold off the one-spot and switched to batteries..

But batteries don't last forever.. and after a few changes i thought I'd buy another onespot to power all the pedals that don't hum.. and kept the "hummers" on batteries. Worked for me! (plus I got rid of the "hummer" pedal eventually)

Now I'm running on a onespot.. but without the hum.

Haha! my Hummer pedal was a Ts-7 as well! there you go!

It's not differing voltages - both pedals take 9v. It's not a polarity issue either.

Igoh's suggestion on using batteries should work well, especially considering TS pedals don't really drain battery power. Just be sure to unplug the patch cable going into the TS7's input jack when you're done if you're powering it on batteries - otherwise it'll continue to exhaust the battery even if your pedal's turned off.

If you're budget conscious the other suggestion is use a separate OneSpot for pedals that do make noise. 2 OneSpots are still cheaper than a dedicated power supply.

 

[Brenkoh]

Oh thanks alot ppl. Hmm wad batteries do the ts-7 run on ?

 

[Danelectrico]

Dude. Practically all pedals use 9v batteries but you would have figured that out for yourself if you'd only actually open the battery compartment.
