this module fits into most rectangular holes in guitars sides to upgrade an existing preamp module
the rich mix of the 3 sounds:
- clear and broad spectrum near string piezo pickup, we recommend L.R.Baggs, RMC or our Rubin
- Polybass subbass effect that never produces a wrong note and seemlessly joines and supports the other sounds
- natural and acoustic sounding in body microphone with 100Hz notch filter to avoid feedback and let the other two channel’s fat bass dominate
the 3 layer plywood front pannel adapts better to the courve of the guitar rib than any plastic or metal because its bendable in one direction but stiff in the other. and it looks better, its real wood!
the microphone can be adjusted like a goose neck: it is so light that a stiff wire is enough to hold it in the position you found to be the best!
