There seems to be a lot of call for something like this. Build a couple of these in small metal BUD-boxes with XLR or 1/4" TRS connectors and keep 'em handy.

Note that this is suitable for line-level devices that want to work into a 600-ohm load. It is NOT for padding mic inputs.
Although not specified on the schematic, the metal chassis of the attenuator should be connected to pin 1 of the XLR jacks or the sleeve of the 1/4" TRS jacks.
Attenuation is 0-50dB in 2dB steps, plus "off", accurate to within 0.1dB, limited by the tolerance of the resistors.
Have fun!
