It is long overdue, but here are a couple of initial tests of mounting piezo transducers in the EGS bridges. I mentioned this already in the beginning of the year after having received samples from GraphTech.
All in all, adapting the tuners to using piezos was very simple. And, for use with the tremolo where individual string height adjustment, the case is closed here. However, when mounting the bridges individually with the fixed version of the bridge, it is necessary to be able to adjust the height of each string. Most likely, I will have to solve this using one or two set screws accessible at an angle from the front of the tuner to adjust height. This means having to release tension from the string in order to adjust height (since it uses the same screw for fastening and adjusting intonation). Some work remains. Also, it remains to find a routing of the cables. This is easier with the upper version (IceTone) that has the cable coming out towards the rear. The regular ghost saddle on the bottom has the cable coming out through the bottom and requires some clearance to be created for it.
Here are some more pictures. Please let me know which is preferrable or if you have ideas on height adjustment.
