Title: My looper (TB box) WAS humming
Post by: warioblast on July 27, 2006, 05:35:01 PM

Hi,
I built a dual looper with tuner mute today, following those diagrams.

I replaced 2 of the mono jacks with 2 stereo ones, I did not wired their rings...
Loops & tuner mute are working but there's a light hum :icon_redface:, even when I'm powering the box off.
I'll do some tweaks tomorrow to find out what's wrong, but any leads or similar experience reports are welcomed :icon_wink:.
Greetings,
Fabrice

It was the easiest fix ever; hum came from not closing the box ::)
Everything works fine now, no hum, no plop. A big thumb up for Andi Allan of monkeyfx.co.uk and Andreas Moller of stinkfoot.se for sharing those diagrams.

It just needs some paint :icon_biggrin:

Hello there, I'm doing something similar; just checking the leg of the LED without the resistor, do they all link up and go the the +ve of the power?

From my experience, all LEDs are not polarised the same. Mines are low current, and the legs of the LEDs WITH resistors are all connected to the +9V.
One easy tip: take a 9V battery, your resistor and LED and just play around with them until the led lights up.

Thanks for this Warioblast,

I just wanted to ask if you wired it like this:

Nice work, warioblast. Any serious pedaller needs a looper like that.
