An old trick for a bell sound is to lift one string over the top of another string with a finger nail (if you have a finger nail). Example, lift the G string and lift it over the D string so that they are crossed. The strings must be touching each other at the cross point, maybe around fret 7-9. Play the stings and let ring. You will get a bell tone. Michael Schenker used to do this. Not so much a technique than an effect.
Garry Moore slide harmonics is a great sound. Example is to hammer on and pull off on the A string 'fret 5 and open A' while sliding the edge of your right hand lightly down the string from the bridge towards the nut.
It's fairly straight forward, if you want to start it , press start. You can work out the rest of the controls for yourself !
No silicon heaven ? preposterous ! Where would all the calculators go ?
