Obviously some of that will depend on your design/setup, but I have just surface mounted them. I don't think they're more than 1/4" thick.
Hi James, I suspect, but I don't know for sure, but many builders new to the game install a piezo pickup into their cbg due to its ease of installation and low cost. This is the quickest easiest way to get an electric guitar. And it could be, up to a point.
The role of the piezo pickup is to amplify an acoustic instrument whilst maintaining the acoustic tone of the instrument, which most don't. When they fit a magnetic pickup they are more pleased with the sound, why? because now they have a true electric guitar, without the issues associated with piezo's in hollow bodied acoustic instruments played at high gain.
Could be a matter of horses for courses. The right pickup in the right guitar for the right reason.
Just a thought. Taff
I have thought about switches, mostly spst, just an on/off for each, then I'd have acoustic, mag pup, piezo pup and both...
Hi, I normally use two volume pots, this way I can balance the mix between a mag and a piezo. I turn one all the way down for off when needed.
If I'm playing on the acoustic p/u I like to slowly bring in the mag p/u enough so as to add a bit more bottom end or fullness to the sound. You need room for three pots if you want tone control too, or a push/pull pot saves space.
I have several 7545R preamps, and some passive preamps (those don't work well) and I hadn't figured how to mount the 7545's in cbg's all the time, but then I hit on the idea of building a stand-alone preamp box. Got a little hobby box, mounted the preamp in the top, hacked the input wire (cut off the rod piezo, wired it to a switching input jack) and mounted the input and output jacks in the front. No more +$10 for cbg's. As a stand-alone it works fine. Now maybe I will use some piezos...
I've done that a while ago and it works just fine. You just have to remember to unplug the lead that goes to the amp when you're done as it also works as a switch.
Took me a while to figure out why a battery didn't last long in mine.
i tend to pop the battery door too...
