What's New?

 

 NEW !!! - FOR SALE page

 

Hello World!  I live in Adelaide, South Australia, and my interests are electric guitar, playing live music, writing MIDI sequences, programming in Visual Basic, dabbling in electronics, with a casual interest in popular science.  I have some years of experience in these fields, and use these Web pages to share my knowledge freely.

  • 11 Dec 02  Several minor clarifications to the calendar pages.

  • 21 Jan 02  Minor revision to my generic overdrive schematic on the overdrive & distortion page.

Spelling! - This is an Australian site, so some words have different spellings than American sites.   The most noticable differences are words ending in "our" like colour and flavour, some words ending in "ise" like realise and organise and words ending in "re" like centre and metre.

Also, in the context of these pages, "valves" and "tubes" are the same thing.
