rhodesworks Posted April 18, 2018 Share Posted April 18, 2018 I have two Line 6 Spider IV 75 amps. I would like to use them as a pair one stage left, one stage right, both being controlled by the same floorboard. I am currently running a guitar cable rather than a wireless rig (thanks FCC). I own an FBV Sohrtboard MkII, FBV Shortboard Mk1, FBV Express MkII, and FBV ExpressMk1 so whichever one would be the better option. What would be the best way to do this?

psarkissian Posted April 18, 2018 Share Posted April 18, 2018 The amps have a supply voltage for FBV boards in the connector. That would double the voltage on the floorboard supply line and risk damage to the circuitry. Which would explain the number of units that come across my repair bench with failed voltage regulators. Don't do that,... please. Quote Link to comment Share on other sites More sharing options...
rhodesworks Posted April 18, 2018 Author Share Posted April 18, 2018 Would it be feasible to wire a junction box, one in, two out with the supply voltage not connected on output #2? Quote Link to comment Share on other sites More sharing options...
psarkissian Posted April 18, 2018 Share Posted April 18, 2018 There may be something commercially available, someone posted a week or two ago here, that is supposed to deal with that. We haven't checked it out here, so anything outside of the normal use of our product is ill advised, unsupported use and at your own risk. Be aware that if this fails, the floor board and the FBV connection circuit on both amps could be damaged. You aren't the first to try this, and as I mentioned earlier, I've seen the results of the failed attempts. It would be unsupported use of the product. It was never designed for that.

rhodesworks Posted April 18, 2018 Author Share Posted April 18, 2018 Thanks for the advice. I used to use Flextone II 2-12 amps and could do this sort of thing over midi. i've also used the Flextone single 12" with the extention cabinet and the Flextone head with two cabs using 1/2 each cab one left one right. Currently as i said I have two Spider IV and was just thinking I'd try it with those. I've actually used quite a bit of Line 6 stuff over the years Thanks again!

psarkissian Posted April 18, 2018 Share Posted April 18, 2018 Yeah,... MIDI I/O is different, there's in, out and thru. Not the case here. Quote Link to comment Share on other sites More sharing options...
fflbrgst Posted April 19, 2018 Share Posted April 19, 2018 Not the solution you are looking for, but you could use the headphone/DI stereo output of one Spider 4 and send that signal to 2 amps/speakers (or to a stereo input on a stereo PA mixer).
