Try a Rat style. I like the Mudhoney by T-Rex. There are others. Or a Klon Clone. I like the MXR Sugar Drive. There are others. Or plug into the Top Boost Channel and crank it? See immediately above. Those are all likely to get better results into a Vox than a TS. I only use a TS style pedal into a Vox style amp when I've already got the Mudhoney on and I want to go for more distortion.
