When I needed to switch between basses and EUB's this was a great tool. Very high quality 2 channel switcher with separate pre amps for each channel and an excellent built in D.I.
You can balance output and toneshape each instrument for quick changes, or use one channel as a boost with one bass.
Included are the AC adapter, manual and a nice little zip case I've kept it in.
$180 takes it postage included.
