So I use a barcus berry currently, mainly because a lot of my design gear and mics come from being a concert engineer. The more I use the barcus I find it to be quite a pain to apply to surfaces that are not a piano soundboard/ or flat. Instead of the little double side sticky that is normal for them, I have resorted to Just electric tape or some form of tape around whatever object I am applying it to, which sometimes changes the sound drastically. What other contact mics do you all use that maybe easier to apply to non flat surfaces, and two, do not need the large preamp box that a barcus requires, but still has the quality.
I do like the way the pickup sounds, but if it is not perfectly flush and against a surface securely, it is almost worthless, and by design that limits it to mainly flat surfaces.
