Modifications for onboard effect
« on: July 11, 2006, 08:04:19 AM »
Hi,

First of all thanks, Aron, for enabling laymen like myself to rise above the confines of our ignorance.

I'd like to adapt the NPN boost for use as an onboard effect, would the following work? (Advice welcomed from anyone.)

I am also curious, is it that simple to add it as an onboard effect?

Yes. Just take the wire that goes to the output jack on your guitar, then desolder it. Take that wire and run it to the input of the NPN boost. Take the output of the NPN-boost and wire it to the output jack of the guitar.

If you want to be able to bypass it (in case the battery runs out), use a DPDT as a toggle with your guitar. You can get one of those push-push or pull pots too.

The hardest part is finding space inside the guitar.

I forgot, you want want to wire a switching jack to output jack of the guitar to turn the preamp on/off. Wire it just like the INPUT jack on the beginner project, except use the output jack's ring for the battery ground.
