Does anyone have any experience with Boss' FS-6?


Is it possible to use the FS6 to separately control the channel and reverb on a Marshall DSL via two cables out of the A and B jacks, to the channel and reverb jacks?

Or do I need one stereo cable from the A&B combined jack on the FS6 and use a splitter to plug it into both channel and reverb jacks on the amp?

If there are any alternatives anyone can suggest to control both the channel/reverb on a DSL they would be appreciated, thanks!
