OK I got the essence of it – a very simple preset to set up.
This time I made a drastic change of guitar.
Last time – modern Fender Strat with 2 point trem and strung with 9s (mainly because I was using this to set up a whole bunch of assorted presets)
This time – Gibson Les Paul strung with 10s
World of difference, far more in tune sounds and great fun with the preset going into a filthy amp.
Really good fun! I can now highly recommend this.
