"Another one for fans of more subtle 'vintage' effects, the Mellow Yellow is similarly easy to operate, with just speed, depth and level controls.

Note that the level on the MYT is not a mixer control as on the phaser, but a master output control. There's quite a generous amount of extra gain available, so to save pedalboard space, you could even use the MYT as a solo boost, with or without the tremolo effect.

Like we say, the tremolo effect is fairly subtle, but what it does, it does very well. The tremolo shape is very smooth and reminiscent of old Fender amp tremolo; it really sounds great for slow, bluesy rhythm guitar, using lightly overdriven singlecoils and a low depth setting.

With the level turned right up, the extra boost is warm and balanced, and we got great results by adding a hint of tremolo with a very fast speed setting. As the Mad Professor team writes in the user manual, this is almost like having a hint of slapback echo."

Mad Professor Mellow Yellow Tremolo (MYT) is a true sine wave tremolo effect designed for tremolo tones from the of 50′s type soft swing to deep modulation with great playability, regardless of tremolo depth or speed.


The strength of the incoming signal is modulated by a sinusoidal oscillator, just like in the early amps, and modulation bias is set to give symmetrical modulation. This gives a very musical tremolo effect that blend very well with both clean and distorted guitar tones.


The MYT has a level control that allows you to even boost the signal for a more powerful effect.


CONTROLS SPEED: Controls the speed of modulation. DEPTH: Controls the depth from barely noticeable to almost full on/off. LEVEL: Is primarily meant to balance level effect on and off- sometimes you need to have a slight boost because the tremolo effect cuts density of sound through pulsating.
