Real quick delivery on the BC Rich bridge - I now have to try and figure out how to attach the wires as there is no lugs to solder to just a tiny hole. I am not sure it was such a great buy - still that's part of the fun of ebay.
Thank you for the interest. I have used piezo discs (the cheap ones) with hardtails on several CBGs as I like the way you can easily lower the action. I tend to use 2 or 3 discs wired parallel (as you probably know this reduces the impedance of the discs which then makes for a "better sound" though on a lazy afternoon I tried wiring several discs parallel and in series and couldn't hear any difference. Also if one disc fails the others still work if wired in parallel). In the video I wired these to one lug of a 5 way switch and two minihumbuckers to the other 2 lugs and then sent the output from these to the preamp using a 2.5mm jack.
The sound is Ok but as I tried to show in the video you do get the extra noise from the box rubbing against you (this can be a plus point if you like to add percussion as you play).
If I was planning to just add a piezo then I would do as you suggest and just solder 2 or 3 discs to a 2.5mm jack and glue them to the underside of the box around the position of the hardtail. Though as a first choice I would also add a magnetic pickup as it is cheap to do and adds extra tonal options.
Nice CBGs you are making - you probably already have a good supplier of parts but if you like hardtails check out Bezdez on ebay - the hardtails are top quality and a great price http://stores.ebay.co.uk/bezdez
I have started a CBN group entitled, "How to Play CBG" It is my hope and intention to encourage the "Wealth of Talent" here on the Nation to share their knowledge and skill to further the CBG movement. Please consider contributing an instructional "video" link to this group. If you are a viewer seeking instruction, please feel free to write. If you have any suggestions or know other players who you think may want to post instructional "video" links, please contact me. Thank you for your interest and support, Keni Lee
