Blending 3 signals

Recommended Posts

I already use a boss LS-2 to blend my clean with my effects chain however i want to have a 3 way blend of clean and 2 effected signals all blended together - effectivly a tri-amp setup but i don't fancy carting 3 amps around.

I was thinking of buying a second LS-2 and using one to blend my 2 effects chains and then using the other to blend the chains with my clean. Or i was considering getting something like this:[url="http://www.woundedpaw.com/catalog/product_info.php?cPath=27&products_id=152"]http://www.woundedpaw.com/catalog/product_info.php?cPath=27&products_id=152[/url]

Does anyone know any other similar blenders? Or should i just get a second LS-2?

Thanks

How's your soldering skills?

I made an effects loop/2 channel mixer pedal & the schematic I used was for a 3 channel.

Ok, i think i might have a go at building one from scratch before i fork out £150 for a new wounded paw blender and i can't find any used ones going on here or ebay at the moment.

Would it be possible for me to add individual volume controls for each loop?

Thanks

You could do it by using two 2-channel blenders. Use one blender to blend two signals, and use the second blender to blend the third signal with the first blender output.

Probably cheaper than a custom 3-way blender.

EDIT: oops, did not read the OP properly! This was your original suggestion - I would go with that as one more LS-2 would be much cheaper and I can't see any drawback other than space.

hmmm, I am sceptical about the effectiveness of a passive blender like that. What do you have in your chains xgsjx? Any problems with levelling?

I just spent >£100 on a SFX pedal which will give me two loops independantly, or the two blended together, with no volume difference between the 4 settings (Dry, A, B, A+B ) and I would like to think it was worth it, but maybe not?

Being passive, I think I lose about 25-30% (though I haven't checked this). I have a volume on the A/B switch to balance between loop or bypass.
Going into the mixer section, if one channel is off the other does not increase in volume, so makes no odds as I just increase the input gain to compensate. So everything is easily balanced to be the same volume regardless of what is or isn't on.
