Smith BMT & BT Circuits
NEW Smith BMT 9/18 volt model Circuit (5 knob)
Standard in all Handmade USA Smith Basses since 2005, modiefid for 9 or 18v use in 2018.
The New Smith BMT 9/18 volt Circuit was designed for Multi venue application with a DIP panel switch and can be used as an 18v or a 9v in models where the 2nd battery will not fit. A shunt is provided for the 2nd battery port if needed to operate as a 9v unit. There is no difference in volume between the 9 & 18 volt units, just slightly longer battery life with 2-batteries. The 6 position DIP switch on the new 9/18 volt model is preset at the factory for optimum performance but adjustments can be made to set it to the original 9 volt setting (pre 2004) or other frequency settings if preferred.
*Note: If you have an older Smith Bass with Series/Parallel switches already installed with the older 9v circuit, use the shunt for the 2nd battery port to operate as a 9v unit.
Control Knobs, Input Jack, Battery Holders are sold separately or as a package. Series/Parallel Switches are sold separately.
