Can I use my own effects pedals with GarageBand?

[stusam81]

Hi.

I'm recording a song in GarageBand and all is going well with the amp mods and in built stop boxes. However, I want to use my Digitech Whammy to get a decent octave down sound (non of the in built effects have this as far as I can see) but when I try and plug in I don't get a signal at all.

Is there a way to get this working? I'm simply using a jack to mini jack converter (like this) and don't have the cash to buy an audio interface. Id this doable or is there any decent pitch shifter plug ins available?

Thans for any help anyone can offer.

I don't use GarageBand, but Reason, my signal path is:
Bass ---> Fx ---> built-in audio input.
It works fine.

But I use a mini jack to 1/4" jack lead. Mini Jack in the iMac, 1/4" in the last fx pedal. That way it reduced the strain on the input socket on the iMac.
This sort of thing

That's pretty much the same path I'm using

Guitar -> FX Pedal -> Computer Audio Input

It works fine if I take the FX out of the chain.

Ps. Just orded a lead to swap for the adapter.
