The Boss LS-2...

@steamabacus - that's a super-tidy board, love great compact setups like that. Nice work! Is that a JD-10 preamp hiding under your GT-OD?

You should see it at the moment! I'm currently rebuilding it and it's a mess of cabling! The new configuration is even more fiendishly compacted which has allowed me to fit an extra pedal on there. And yes, that is a JD-10 - I've used them for years. I have three of them - one used as an overdrive on the board, one used as a pre-amp/speaker emulator for direct recording and one spare. My new board setup includes a new power supply which allows me to run the JD-10 at 18V (they sound better ta higher voltages).
I'll post pics of the new board when (if?) I finish it.

Still have the circuit somewhere, but no jacks and no schematic.

Damn, I could have done with that PCB recently.

If you find it, can you let me know? No hurry now though.

In short - the Boss LS-2 is a great pedal for what it does, if it fits on your board! It's one of the most useful pedals there is for many different applications.

But it's such a nightmare to work on that if you break it, it's probably cheaper to buy a new one than have it repaired. This particularly applies if you've used the wrong power supply and cooked some stuff on the board...

Oh I know where the PCB is, it's in my little box o' tricks. Got a few knackered Behringer bits too!

So have I .

I'll file the knowledge of where there is a spare LS-2 board away for future reference . I wish we'd had this conversation a month ago!

I did think about asking you if it was repairable, but at the time I was incommunicado!

@ICBM - I don't suppose you would happen to have a schematic for the LS-2 would you? I want to fix mine, which I broke apart trying to solve this very issue, but then gave up at some point. This has just been sitting in a box, and I could do with it for a new project!



From what I can see there are 9 contacts I'm going to need to deal with. 7 have wire, two of them don't (I guess it got pulled out, as I can see a tiny bit of wire in the hole... can be desoldered)

On the left hand side points 1 and 2 (brown and white wire) seem to be related to the power so is possible they went to the old battery clip. There is also point 5, the furthest white wire, which I think may be to a jack, as with point 22. Then on the right side, point 20, 21, and 23 (red, green, yellow) which I think go to some jacks also...

Points 6 and 28 are the ones that lack longer wires, so I'll need to replace them.

Phew.... any thoughts??

I don't have a schematic, but I may have enough left of the one with the dead board that I can work it out - I'll have a look tomorrow.

Would be much appreciated

Try this link for the schem :

OK, I found it, and it's relatively intact!

Here are the wire connections from the main PCB:

1 - brown - input jack ring (battery negative)

2 - white - input jack ground

3 - red - battery positive

4 - orange - LED PCB

5 - white - send jack PCB

6 - orange - send jack PCB

20 - orange - return A hot

21 - green - return B hot

22 - white - output jack

23 - yellow - input jack tip

24 - yellow - pot PCB

25 - blue - pot PCB

26 - red - red LED

27 - green - green LED

28 - purple - switch

(7-19 are presumably the ribbon cable)

Good luck .

Oooo you saucy man you. Thanks very much. Will get on it this week!

The LS-2 is a great pedal.  You need a very large pedal board to accommodate it - simply put it on the floor [beside the Wah?].  There the sockets are open and easily accessed.  This is how I use mine.  If I were a gigging guitar player, I would fit the LS-2 and the Wah onto a separate board but I am not so the floor is fine.

Bahhhhh... I can't find the original jacks

Need replacements. But I doubt there is enough room for regular jacks.

No, you need special ones.

You can have the ones from this one… the board is fried, and it isn't worth fixing. PM me your address!
