I bought a new Micro Cube amp and didn't realize that the out jack had been changed from the previous 1/4" size to 1/8".<br /> <br /> How hard would it be to change out the 1/8" plug and replace it with a 1/4" plug like they used to come with?<br /> <br /> Thanks for your help!<br /> <br /> 6

Probably not too hard, but I've never been inside one.<br /> <br /> <br /> Would an adapter work?<br /> <br />

Pinetree: Yes, I already have that adaptor and it will work. <br /> <br /> However, the 1/8" plug is so weak that it would be quickly broken off when gigging.<br /> <br /> 6

The existing 1/8" jack is most probably board mounted. That means the footprint won't match a 1/4" jack.<br /> <br /> But all is not lost. Get yourself a Cliff TRS switching jack. Cliff is the one for two reasons: it's good quality, and it has a plastic body which keeps it insulated from the panel you mount it to.<br /> <br /> Desolder the 1/8" jack from the board. On each of the now-vacant solder pads, solder in a jumper wire about 3" long to allow you to make connections to the new 1/4" jack that's mounted close by in a hole you've drilled in the rear panel.<br /> <br /> You can use a meter to test the 1/8" jack's contacts and where they connect to the board, and match that scheme to the new 1/4" jack.

Solved the problem by swapping a friend for an older one with the 1/4â line out.<br /> <br /> 6

I think that adapter is available in a right angle style as well. So you don't kill it accidentally. I get a bit anxious about adapters that project out too far. <br /> <br />
