(DIY) 3.5mm jack adapter to 2.5mm output

[Rui Luis]

Hello, I have a curly jack cable adapter, in which the male is a 3.5 mm, and the female -also- a 3.5 mm. So it doesn't actually make any sense for me, nor is it usable.
I lost my tiny piece to convert 3.5 mm jack to 2.5, so, I was thinking about:
1) Cutting the male jack cable adapter that I have,
2) Connecting old earphones 2.5 mm jack.

That way I could connect my electro-acoustic guitar jack to my PC, so I can use AmpliTube3. ^^

Concerning the fact that I'm not interested in buying a new adapter...
Can this be done the way I just said, or is there an incompatibility?

Thanks a lot.

Best regards,
RL.

PCs use 3.5mm jacks

In that case, the curly cable adapter I have is from amp jack to amp jack. The large ones.
I want to cut out the jack from this adapter, and connect the small jack from the old phones.
Would this do the trick?

Thanks in advance.

Yes amp jacks are 6mm/ 1/4". you would have to fit a 3.5mm plug to plug directly into a Computer (PC) but beware computer sockets are stereo. You need to use a stereo 3.5mm plug.

"Need" is a strong word ... i'd go with "might want".
3.5 (and 2.5, and 1/4" ) phone plugs + jacks are cross-compatible mono or stereo. plug either into either and at worst, you get mono. Nothing breaks, and nothing shorts out (if the stereo source is not 2 ch with common ground, you cant use a stereo phone plug for audio out in the first place).

Since his guitar is probably mono out anyway using a stereo plug doesnt change a thing, and his stereo soundcard jack will still get two mono channels into his software.
