Lehle footswitch on board
The Basswitch Sonic Spark is equipped with a high quality Lehle footswitch. An actuator button activates a pushbutton via a metal lever and the load exerted by the foot is absorbed by the actuator button and the housing, preserving the circuit board from mechanical stress. Inside the Basswitch Sonic Spark the impulse from the pushbutton activates special gold plated relays via discrete logic circuitry guaranteeing signal loss free switching of very sensitive signals. The switching technology in the Basswitch Sonic Spark is designed to operate for up to two million switching cycles!
Lehle True Sound Technology inside
Lehle True Sound Technology combines a series of electrical design measures to insure an optimal treatment of the electrical signal of the instrument. The supplied voltage is rectified, filtered, stabilized and brought to 18V. This allows for sufficient headroom even when confronted with strong pickup power peaks. The Lehle buffers effortlessly handle signals reaching the megahertz range. At the output, the frequency bandwidth is limited to the audible frequency range to prevent HF interference. The Lehle True Sound Technology is a key element to the outstanding sonic performance of our products.
