Single Channel Attenuator

I'm looking for a single channel, single ended, passive attenuator. I could build one, but would prefer to just buy it. I would like the cost to be low, under $100. This does not need to be audiophile grade but it can't be of poor quality either. It is being used to set a level for some basic acoustical measurements. Any ideas or products or companies that may have such a device would be helpful.

EVS makes a stepped attenuator with 2db increments (can be special ordered with 1dB steps), but it's $150 each.

You can go to SamAsh music stor and get guitar attenuators.
Gibson might be expencive but I don't think over $100. I know they work great on DIY audio gear as well.

A "single channel single ended passive attenuator" is a potentiometer (pot for short) and will cost you about $3.50 in Radio Shack. Throw in RCA plug and jack and you're up to $5.00. Assumng you have a solid state preamp with output impedance of 50 ohms or less, a 10K pot will work fine. If this is a temporary experiment, keep the output wire short and you don't need to install the Pot in any sort of enclosure.

RadioSnack ones to my belief has no application whatsoever and never last even a day or two before you start hearing the fried bacon out of them.
For a true budget high quality ones you should visit www.mouser.com Please note that from their catalogue you can have a greater choice rathrer than ordering from the internet.
