Guitar pedal Bass mod soldering problem

[darnellbass]

I modded a Roger Mayer classic fuzz by  increasing the value of both electrolytic capacitors to 22uf/50V and the 10nF blue box
cap from 10nF to 100nF. The first day it worked fine but when I used the pedal the next day it started to fizz/fart out on me. Re soldered and replaced with 2 newer parts but now its the same bad sound. What have I done wrong; did I solder wrong, burn the board, etc.? Anyone have problems with this? This is my first mod I've done. I have pics but not sure how to upload them

Pics have to be linked to externally with [img] tags.

If the 22uF caps are electrolytic and polarized, one or both could be wrong way around?

Maybe, thanks. I can tell you its not the most pro solder job either.

I've modded both a classic and stone fuzz with the same problem. It works for a while then just either doesn't give sound or fizzes out. Then sometime it works again. Anyone know why pedals do this; the solder looks fine.

Could be a thermal problem where a connection intermittently makes/breaks as it heats up.  Possibly a part was overheated during soldering or a solder joint is bad.  You've said it's "not the most pro solder job", but you've also said the solder "looks fine." Time to show us a picture or two, I think.  (You can't upload pics here, but you can link to them).

if you have dropbox you can embed the image in the post by clicking the picture button above which adds the "(img][/img)" tags.  Past the link between the two tags.  To embed the image within the post though you need to change the link to read "?raw=1" at the end instead of "?dl=0".

Hope that helps.  If you have dropbox that is....

Most likely some caps were overheated, Ill try to do a better job. If it doesn't work out I'll just take it in some wear. Don't want to waste the $ on those pedals. I'll unsubscribe from this thread for now. Thanks for the comments.
