![]() ![]() I have a tone and volume control and 2 transducers. You are spot on Jim once again! I am confused. It sounds like you need to do more research into the function and capabilities of piezo transducers - and instrumnts that have already been made by the thousands for decades.ġ930's/40's Rickenbacher/Rickenbacker 6&8 string lap steelsġ921 Weissenborn Style 2 Hilo&Schireson hollownecksġ959 Fender 400 9+2 B6 1960's Fender 800 3+3+2 1948 Fender Dual-8 Professional ![]() That's not a "lap steel" - it's essentially a take on a Weissenborn style instrument, or a Dobro styler guitar with no resoinator.īoth have been built since the early 1900's with peizo (or other) pickups added later.īut again - there are not "volume" or "tone" piezos. You can then process the output from one or more piezo elements (you can place more than one on an instrument) through a powered preamplifier to boost the signal that has volume and tone potentiometers or faders (an active preamp) or just a volume potentiokmeter and tone potentiometer in a "passive (non powered) circuit.īUT -you would need to build a hoollow body guitar and use aone or more piezeos (and a preamp). If we were to add passive volume and tone controls, the piezo pickup would be loaded so heavily that it would be useless. There are other factors that further complicate the situation. ![]() This would have to be factored into an analysis of the piezo pickup. A piezo element is simply a transducer that picks up vibrations from a surface and sends a low-voltage output through a wire. Typical cord capacitances range from about 50 pF/m to 150 pF/m. I think you're confused - you might have a volume control and tone control - but there is no such thing as a "tone piezo" or "volume piezo". ![]()
