Maxon Talking Machine TM505

Description

The Maxon Talking Machine TM505 is a wah-style pedal that creates vowel-like formant sweeps rather than a traditional band-pass filter sweep. Its treadle controls the center frequency of a resonant filter, producing speech-like "wah" and "talk" effects as the pedal is rocked. A range switch alters the sweep width, letting the filter travel across a narrower or wider frequency span for subtler or more exaggerated vocal tones. The pedal includes a level control to balance the effected signal against the dry guitar signal, and a tone control shapes the overall brightness of the filtered sound. An internal trimmer adjusts the filter's resonance, increasing or decreasing the intensity of the formant peaks. The TM505 operates on a standard 9V DC power supply and features true bypass switching, ensuring the dry signal remains uncolored when the effect is disengaged.
