Sambo Posted February 27, 2005 Report Share Posted February 27, 2005 Hello Y'all. I'm making a copy of a musicman petrucci (pics coming soon ) with a piezo bridge pickup (in this case a Baggs X-bridge). Now, i've got the wiring sorted on a stereo jack, but, i want to have another jack, that when a jack is plugged into it it turns both jacks into mono (one for magnetic, one for piezo) Anyone got any ideas on how to achieve this?! Thanks! Quote Link to comment Share on other sites More sharing options...
Dugz Ink Posted February 27, 2005 Report Share Posted February 27, 2005 Some home stereos have a headphone jack that allows the audio to pass to the speakers unless headphones are plugged in. A lot of those have extended prongs, that would touch contacts until you plugged in the headphones; then the plug would push the prongs far enough to break the contact(s) for the speakers. However, when you consider how prone that type of connection is to RFI, you probably want to avoid it. I would think that a mini-switch would be easier and less prone to problems.

thedoctor Posted February 27, 2005 Report Share Posted February 27, 2005 No problem. Take a stereo (TRS) jack and bend the ring finger so it touches the top of the tip finger without a plug in the jack. Make sure the insertion of a plug lets the two fingers seperate just a bit but the tip finger still has good contact with the tip of the plug. You can buy them like this but probly hard to find. Take the pickup wire off the ring connection of the other jack and attach it to the tip connection of your modified jack. Run a jumper from ring connection to ring connection. Presto! Rickenbacher split-pickup jack! Quote Link to comment Share on other sites More sharing options...
Sambo Posted February 27, 2005 Author Report Share Posted February 27, 2005 Just had to draw that out to check it wouldn't attach one of the pickups to the ground when two mono cables were inserted, but that looks good dude. Thanks for the tip! Ill let ya know how it goes. Just gotta get another switchcraft stereo Quote Link to comment Share on other sites More sharing options...
thedoctor Posted February 27, 2005 Report Share Posted February 27, 2005 (edited) Sambo, I have been wrong before (lord knows) but Rickenbacher and Ed Roman NEVER have! Just ask Ed! lol lol lol lol, etc. By the way, there will be no RFI, GMC, TWA or UFO interference problems with this jack/switch. It just has to make "decent" connection when the tip and ring fingers come together. Don't know the body style of this axe but shield everything, when possible. As always!

Sambo Posted February 27, 2005 Author Report Share Posted February 27, 2005 On the question of shielding, do people find the electrical shielding paint to be sufficient, or do they prefer to copper film everything? Quote Link to comment Share on other sites More sharing options...
thedoctor Posted February 27, 2005 Report Share Posted February 27, 2005 Explain the body style to me. Shielding of a solid-body is best done with the copperfoil/tape but some body styles make that impossible. If you are dealing with cavities carved/routed out of solid wood, copperfoil is the best. Semi-hollows take a completely different treatment. The conductive paint is not only a comprimise IMHO but you can do the coppershield faster and cheaper. You can solder to the coppershields and you don't have to mask off anything to do it. Also, no drying time. If you are looking at two output jack orifices (which I think you are) the output jack holes need to be shielded as well. Then all shielding needs to be hooked together with a seperate ground conductor. The pockets for the output jacks is where I always have problems. Seems any stray strands always find the shielding.

lovekraft Posted February 27, 2005 Report Share Posted February 27, 2005 (edited) Wouldn't a switch jack be a lot simpler? <EDIT>Like tis one? http://www.mouser.com/index.cfm?handler=di...e_pcodeid=50202 Edited February 27, 2005 by lovekraft Quote Link to comment Share on other sites More sharing options...
Dugz Ink Posted February 27, 2005 Report Share Posted February 27, 2005 By the way, there will be no RFI, GMC, TWA or UFO interference problems with this jack/switch. It just has to make "decent" connection when the tip and ring fingers come together. If that connection is not "decent" (ie: barely touching) you can pick up radio stations. Been there, heard that. That's the only reason I have reservations. If Sambo does a nice tight job, then you're right... but I hate recommending that kind of thing without some warning(s).

Sambo Posted February 27, 2005 Author Report Share Posted February 27, 2005 Although i like the doc's idea, the 'proper' switched jacks are the same price as a stereo one in my local supplier. So, i think i'll be getting one of those instead. Quote Link to comment Share on other sites More sharing options...
