Trying to become a better guitar player, I often draw scale patterns on fretboard templates. Depending on the context, I sometimes want to highlight note names, intervals or colours (sometimes all of these). Yesterday, I discovered this little free tool, which can do everything I ever needed:

Example? I am trying to learn hybrid scales (e.g. minor pentatonics with mixolydian) and use half-diminished scales for specific blues transitions (I->IV and V->I). Here is what I created with it: http://www.guitarscientist.com/generator/vg087QDkdNwLrG1 (Minor bug: It does not seem to remember the notation for the "6" and displays it as "bb7". You can change that in the notation tab at the bottom).
If you have other recommendations for good online tools that you really use, it would be great if you could post them here.
That looks great - thanks for sharing!
