    I just got my Sansamp Bass DI and noticed that when I plugged it into the PA it started picking up radio stations. I switched the ground switch which got rid of it, but is that how it's suppose to work? Do I have a defective one? Any advice is appreciated. Thanks.

    I must admit that I haven't noticed that problem myself... but the ground loop switch is provided to solve 'extraneous noise' issues.

    I've used one for the past 2 years, in probably 60-70 different locations, and have never had that problem. Maybe something to do with the shielding (or lack thereof) of the cables, or maybe the PA itself?

    The sansamp bass DI is just about my favorite pedal- I've used it in many gigs, many locations- have never had this problem.

    I agree it could be something else, or if it truly is the sansamp unit then you have a defective/odd one.

    Was it at least picking up some good tunes on the radio? (ha ha)

    You might try a different length cable. I read once that the cable can act as an antenae and pickup radio stations. I have never heard of the SABDI picking it up either. Trying a different length would be a cheap and easy fix.

    I think the shielding would be a good start too. Both may be tested by picking a good quality different length cable.

    Good luck!

    I had the same problem once a long while ago with my Ibanez PD-7, I found that it was my amp placement, in conjunction with the sequence of pedals. I moved my pedals around in such a way that it would only happen if the level was up high enough. Then I switched spots with the guitarist and it went away completely, I guess its just the certain spots that electronics pick up radio signals, or maybe thats just my case.

    Kinda weird but....


    Don't loop your cables where they can cross other cables and don't run the cables OVER your amp. Cross cables at 90 degrees. If you try that, you should eliminate 90% of all noise you can pick up.

    I have never experienced that situation with the Sans Amp BDDI, but my guitarist has (with a different rig). The above measures cured it. They will also cure any AC hum (usually... if it is not a grounding problem).

    I pick a slight radio signal when I switch my bass from passive to active. It only happens when I am practicing and in active mode. At this time I use a short coiled 'Radio Shack' brand cable. I am guessing that the cable does not provide sufficient shielding and thus is an antennae.

    It was really funny when I was jamming out and I began to pick up mariachi (spelling?) music. "What is that!" :eek:
