Product Overview
- IN: A standard 1/4″(TS) input jack.
- OUT: A standard 1/4″(TS) output jack sending a mono output signal to whatever comes next in your signal chain.
- POWER: The TREMU-TRON runs on a 9V DC power supply center negative, draw 15mA.
- WAVE: Shape of LFO waveform. Turning knob clockwise will form a sine wave which has “softer” edges. Turning knob counter-clockwise will form a square wave with will make the “edges” much more “choppy” and pronounced.
- LEVEL: The overall output level. Turning knob clockwise increases the output level. Turning knob counter-clockwise will decrease the output level. In TREM mode, the LEVEL will work inversely to the blend control. In BOOST mode, the LEVEL knob has much more gain. Please use accordingly and do not scare your bandmates or the audience.
- SPEED: Controls the speed of the LFO. A slower speed will create a more subtle tremolo, while faster speeds will create a more pronouced tremolo.
- BLEND: Controls the intensity of tremolo signal to dry signal. As you turn the blend control clockwise, the dry signal will disappear and tremolo signal will become more pronounced. By turning the blend knob all the way counter-clockwise, the pedal will be in “boost” mode. The tremolo signal will disappear and the remaining dry signal will be “boosted” and may now be controlled by the LEVEL knob.
- EFFECT FOOTSWITCH: Determines whether the TREMU-TRON effect is engaged or bypassed. – EFFECT LED: When the green LED is OFF, the TREMU-TRON effect is bypassed. When the green LED is ON, the TREMU-TRON effect is engaged.
Operating Instructions:
The Mu-Tron TREMU-TRON is an optical tremolo effect which can be used as a “clean boost”. It features the famous Mu-Drive preamp from the original Mu- iron Ill envelope filter. By utilizing an 18 volt dual-rail internal power supply, the TREMU-TRON provides a crisp, clean signal and high headroom. The TREMU-TRON utilizes Mu-Tron’s patented opto-mod technology to provide classic, hi-fidelity attenuation without extra noise artifacts. The TREMU-TRON is designed to make non-tremolo tube and solid state instrument amplifiers to have the same rich tremolo found in vintage Fender and Vox amplifiers. The TREMU-TRON pedal should be placed after overdrive and before reverb in the signal chain. The TREMU-TRON may also be used as a boost to push the tubes on traditionally clean amps such as Fender blackface types, it can also be used to “beef-up” the front end of sterile solid-state type amplifiers or mixing consoles. The TREMU-TRON has the same quality, ruggedness, and reliability that makes Mu-iron the first choice of professional musicians.
