hey guys,
so i put together a king of klones board wired it up
and bypass is all gravy but no sound when engaged
i can hear pots wipe and switches pop and what not
i did the normal checks or wires and grounding but no love
i used the wrong ic the jrc4588D instead of the JRC4580D
maybe thats issue number one
ill post some guts if the ic cant be subbed
cheers
That iC should be fine, its a common replacement.
Have you checked your parts and wiring?

Hey Tuffteef ;D
Measure the voltage at every pin of the transistor and IC and post them here i.e.
Q1
C - 9
B - 4.5
E - 0
IC1
1 - 4.5
2 - 4.5
3 - 4.5
etc...
Use an Audio Probe (Shown here - http://www.diystompboxes.com/wiki/index.php?title=Debugging )
And go trace the signal through the schematic to find out where you're loosing signal.
And as Jkokura said, Check all your component values, wiring & make sure all your solder joints look good + no hair width solder shorts (check the back of the board with a magnifying glass, or my personal preference, put a high intensity light behind the board).
scruffffie! ;D
TIS I THE QUEEN OF ILOVEFUZZ.COM!
i did some checking i had a solder bridge on the ic and one of the pot wires was a tad wiggly
fixed those and it worked! thank yall
that input bass cap mod is no joke eaither
it should say do it TRUST ME!
It's always good to double check little things like that!
I have an Aristcrat I plan on building soon and I really wanna go for all the mods possible. No one else has really mentioned the bass input mod, it's something I'm gonna do on mine. Did you bring the C1 cap value all the way up to 47n or just 27n?
I went with 33n and I think it's a good match for my telecasters.
i put a 47n and 22n on a dpdt switch for convenience id like more bass though but its more than the original 10n
