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.
