Boss line selector question

[Quatschmacher]

Hi guys,

I wonder if boss line selector users in here might be able to help. I was wondering if I could use the LC-2 in "A+B Mix" mode in conjunction with a Q-Tron to get a mix of the dry and wet signal. The original Q-Tron has a separate "direct out" socket. My idea would be:

plug the bass into the input of the LS-2;
plug "line A send" into the Q-Tron;
plug the "effect out" of the Q-Tron into "line A return" of the LS-2;
Plug the "direct out" of the Q-Tron into "line B return" of the LS-2.

My question is, would that work because I wouldn't be sending any signal from the "line B send"? From what I can gather from the block diagram, it appears that the line volume is applied to the received return signal as opposed to the sent signal. Also, would I need to have a jack plugged into "line B send" in order for that line to be activated?

Thanks

I think it just mixes with the clean signal if you leave one of the loops empty, but you could always just use a patch lead to run straight from the send to the return.

The other option is to plug the bass into the Q-Tron, take the wet out of the Q-Tron into return A, and the dry out of the Q-Tron into return B, and the output of the LS-2 will go to the next in the chain - this definitely works

If you just want a clean blend and none of the other functions of the LS-2 I'd buy a clean blend pedal as it'll be simpler and cheaper

I hadn't thought of going from send straight to return. That's a good idea! Thanks.

I'll check out a clean blend pedal too, thanks for the suggestion. However, I'm sure there are other ways I could use the LS-2 too.

I'm basically trying to achieve the function of the "dry" and "fx" knobs of the MXR M82 but using a Q-Tron instead.

That will work perfectly, as the LS-2 works via the Return Jacks. I use mine as an A/B switch for 2 basses simply by plugging nothing into the input, and a Bass into each return. Set it to A<->B and you have a 2 channel instrument selector with variable gain to match the output levels between basses. Then just take the normal output to the next pedal as normal. Works a treat! You wouldn't need anything plugged into the Send of B.

Surprised that works Higgie, according to tfm you need something plugged into the input jack to turn the unit on, even if it's just a plug with no cable.

I don't know, mine seems to work! I regularly use it with just one bass straight into the return of A, and then switch to B to act as a mute! If you were using it with batteries I could definitely see a problem? Using it with a power supply seems to be fine. As it's one of those Boss Pedals that can distribute power from a second jack, maybe it's always on once you connect a power supply to it?

Thanks for the replies guys.

Yes, I think the input functions as a switch in battery mode but when a PSU is connected it is always on.

I've been reading up on pedals a fair bit and just seen that Mike Beigel has launched a Micro-Tron III, which is a small pedal version of the original Mu-Tron III but with a level control knob! I have so much envelope filter gas right now!

Yes, that'll be it. Something else I have not yet tried with mine, such a useful pedal I wouldn't be without one!

The LS-2 is one of the best things you can buy. It's like a Swiss Army Pedal! I would advise anyone to have one in their arsenal.
