   I have the Spider IV 30 -- the old model, with just four presets.  When I change from one preset channel to another, on some channels I get hum/buzz/static, which disappears when I fiddle with the channel volume/drive knobs.  Is this just one of those things that everyone experiences or can I adjust something to eliminate/minimize that?  I also noticed that the volume differs from preset channel to channel -- goes way up or down as I switch.  Any way to standardize the volume so that it remains the same as I change channels?

I have noticed some noice when i sit too close my computer, try move away from any electric things and see if it helps. Its also important to have a good quality cable to your guitar. I noticed big differences between good and bad cables.

You can save your altered settings to the 4 preset locations, including any channel volume change you have made.  If you are using a guitar with single coil pickups, and have the compression setting dialed up, the noise will be noticeable until you hit a string.   You can adjust the compression settings and turn on the noise gate and adjust that to combat noise.

I got the cable when I bought my amp -- Neutrik -- per the salesman's recommendation.  Is that good -- or good enough?  If not, what do you suggest?

Unless you have an old 'tube style' (non-LCD flat screen) computer monitor, the only RFI interference that you might get from your computer is if you are using a laptop with a power supply.  Humm/buzz can be checked in this situation by running the laptop on battery to see if the noise disappears.

Noise in the signal varies with the amount of gain in the preset. The higher the gain in the preset the more noise you will hear. This is normal for all electronics.

I think that is good enough :)
