How To Add An External Speaker Jack To (Almost) Any Guitar Combo

Have you ever wished you could turn your guitar combo amp into a head? You can! It's pretty easy actually. The secret is to use a shunted mono jack (Switchcraft part# 12A). I demonstrate on a battery powered amp, but this technique should work on most combo amps from 1 watt to 100 watts.

Thanks for watching Doug. I figured some folks would get something out of it. We are all DIY'ers after all.

I almost passed on this video Kale! But I’m glad I didn’t! I could hear a serious difference at the end in the volume and tone! Wow! That is a cool special purpose jack and I would never have known about it. Thanks for an amazingly useful video lesson.
