This is how the mules sounds when I use my TIM pedal too boost the input stage of my marshall 1974x to get a more high-gain sound.
unpotted mules, alnico 4, bridge pickup. Tremolo channel volume about 11 o'clock, tone 12 o'clock. Tim is set mostly to boost with the gain knob set to approximately 9 o'clock and the volume knob on 3.
Hope my clips help. I'm trying to show as different things as possible...
