Hi Harry,
One of the amps Michael profiled in his Vintage pack was a Polytone Mini Brute Mark 3 ...

This amp was/is used by a lot of Jazz guitarists (George Benson, Joe Pass amongst others) due to its round, smooth and woody sound.
With the 'rolled-off' tone knob I meant slightly cutting the treble of the neck pup of your Strat by dialling back the tone knob for the pup.
