LS-2 in a rack?

[pmag55]

Well I tried to hook up a Boss LS-2 in my rack to A/B 2 preamps . The best I could do was actually play music with both preamps turned OFF ! (weird). Anyone know how to do this hook-up?

Man, I think I was the one to tell you to get the LS-2. I don't own one but know how it goes.

Guitar- Input LS-2
Loop A- Preamp - Preamp out to LS-2 A return
Loop B- Peramp 2 - Preamp 2 out to LS-2 B return
LS-2 output to your FX.

ls-2 in a rack

Ok, I tried it, no go. the same thing happened, when I switched to loop B i got sound, loop A, none. it turned out though the sound is not coming from the preamp, its coming from the JFX-1. I read that the JFX-1 has a little preamp in it. I double checked and unplugged wires as the notes were ringing. preamps were NOT transmitting sound , when I unplugged from the JFX-1, the sound stopped. Crazy huh?

Check the dB levels on the LS-2, maybe they are not set correctly. Failing that have a look on line for wiring setups for the Boss LS-2

That should work ....

If you have no sound coming from Loop A , may be a problem with the LS2 pedal ???


Do you have the function knob set correctly ???

 

[pmag55]

Yes, I have tried each setting on the ls-2 with A and B and on some settings I get sound but it is always through the jfx-1. Maybe the ls-2 doesn't work with line level gear? their instructions only show pedals being hooked to it.

You may have to put a call to email into Boss / Roland tech. support and see what they say ???

Question ???

Is there anyway to show us your routing in more detail ??

download the application manual-
BOSS U.S. - LS-2: Line Selector

I don't know how to "show" stuff on forums, but I routed the lines as suggested.
Pre A to LS2 A return--Pre B to LS2 B return--LS2 output to FX--guitar to LS2 input.
Both A and B have a cable going to their 'returns' from the preamps but not coming out of their 'sends' , should there be?

*Guitar should go IN and OUT of LS2 and out to amp input .
*LS2 Loop A send , to Rack effect input
*Rack effect send or out , to LS2 return

do this for both of your Rack units ....

It didn't work Hot tubes. I don't think the ls-2 works with rack gear. Back to the store to get my $80 back and spend $1200 on a gcx, gcp and cables.( my mother never raised any fools except one.) Thanks everyone for your help.

Sorry we could not make'r happen !!!!
Best of Luck eh !!!

 

[pmag55]

Well we tried. I tried all the configurations I could think of. The preamps SHOULD hook up just like pedals but no luck. I think the ls2 might not be working or else it doesn't handle rack gear to well. Thanks for your help ,it was greatly appreciated.

Crazy thought here ..... but maybe you got a bad Boss LS 2 ???
Crazier shit has happened ...

ditch the rack fx for now & go straight into the preamps to test it.

I tried one only . No sound unless I hook up the jfx-1 with it but when I unhook the jfx-1, no sound again. I think that little preamp in the jfx-1 is the only thing working through the ls-2. Anyway I returned it. For now I've put that idea to rest as I have OD'd on tylonol trying to get rid of the headache it gave me. Thanks guys , I think there must be a problem between 1 loop and the output of that unit. I'll try something else for now.
