pedal mod diagnostics HELP

[scottish]

k so i modded my ts9

when its in my chain, the signal passes through fine, but when i turn it on it cuts off the signal. the LED goes on, it has power and everything but nothing passes through it.

did i maybe jump two connections that shouldnt be connected?

It might be helpful to know what you were trying to do when you whipped out the soldering iron.

Re: pedal mod diagnostics HELP

you mean i should have known what i was doing? or you need to know to help diagnose the problem?

generally i know what im doing, i modded my 3 boss pedals no problem. if it helps, i was doing the monte allums ts9 mod

The latter. There are a number of issues that can cause the symptoms you describe. Telling us what you were tweaking would help narrow it down.

Assuming that you already carefully inspected the solder joints on the other side of the board for any cold joints or places that a weld may have touched something it shouldnt have.....

I offer no help whatso ever

good luck!

Did you point those tantalums the right way???
(who uses tantalum caps in od's??)
And is the OP-Amp firmly socketed?
P'S got any pics of that pedal after the mod, preferly from the solder side!

Re: pedal mod diagnostics HELP

im thinking cold solder was the problem. i modded both my ts9s at once and i just got one of them working by redoing some solder joins. hopefully this is problem with the other one too. Thanks guys
