Aron Smash Drive!! HELP!!

Building this currently
http://www.aronnelson.com/gallery/main.php/v/TheBigMan-Layouts/smashdrive.gif.html

however, it does not have a volume control..even with all pots down, when the efx is on, some signal will still pass thru.
anybody knows how to put a volume control pot??

ARon!! help.

[humptydumpty]

to the best of my knowledge, take the output wire, connect it to lug 3 of a 100k pot, connect lug 1 to ground, and lug 2 to the output jack

edit: someone correct me if im wrong

[compuwade]

You should be able to connect the output from the circuit to a 500ka pot and then to the output jack. That should give you a good volume control. Kinda like this one

lol it does not work humpty, no sound at all from efx. hiaz..
lol compuwade i cant really read the pcb..
edit* followed pcb. vol pot lug 1 to grd and mid lug 1? thats wad i see it.
still wun work

[anchovie]

For the "Killer" version: Remove any connection from Treble lug 2 to output. Connect Treble lug 2 to Volume lug 3, Volume lug 1 to ground. Volume lug 2 is output.

lol thats wad i did bro.
as said by humpty. now not even a sound from it.

[anchovie]

Do you get sound back if you remove the wire from Volume lug 3 and take the output from there?

[1tczx]

yes before i added the volume pot there was sound. after that, totally disengaged. lol /

[anchovie]

That's not what I asked. Does the circuit work again if you take the volume pot off?

[1tczx]

ya it does. but once i connect to lug 3 agn it became silent. help still needed!!

[anchovie]

Can you post some pictures?

[1tczx]

the 2 pots u see are the tremble and volume pot. output was originally from tremble lug 2...

[anchovie]

You can ruin pots by soldering in those holes, that's not what they're for. Got a DMM so you can measure the volume pot resistance?

[1tczx]

haha its easier to solder in wires into holes volume pot working fine. all way down 0 ohms , all ways up 500k ohms

[anchovie]

OK, measure the resistance between volume lug 2 and the output jack (to check the yellow wire) and volume lug 2 to ground (with pot at max).

[1tczx]

lug 2 to output jack ok, 0ohms.
lug 2 to grd full 500kohms at max pot.
all working well...

[anchovie]

And just to confirm, 0 ohms between lugs 2 & 3 of the volume pot at max? If that's the case and you've got sound at the end of that wire coming from the treble pot, then hooking it up to volume lug 3 should, in theory, work. If it still doesn't then I'm stumped!

[1tczx]

err bro for ur last qn, there is no reading between lug2 and lug3 of volume at max...why..

[humptydumpty]

is it/was it connected like above? cuz im missing the whole treble and volume connection if it is

[anchovie]

err bro for ur last qn, there is no reading between lug2 and lug3 of volume at max...why..

If it's open circuit between those two lugs then the pot is damaged and you won't get any sound at the output no matter where the control is set. Best replace it and not solder into those holes this time!
