Guitar 'synth' Update

Debugged the new waveshaper circuitry. Works very well using a technique rarely (if ever) seen in audio stuff. Also added a simple ring modulator a'la Korg MS-20 which works very well with the oscillators footswitchable 'note hold'-function.
Some of the 'typical' synth waveforms didn't sound interesting enough and got replaced by  my own weirdo concoctions..
