About the sample settings:

These sample settings are not provided as a proof and comparison study, but as a starting point that steers you towards a certain character of tone. (Usually one of my favorite amps) give or take a worn tube or speaker, or whatever other factor may color your perception of tone.

These sample settings were done with a maple neck telecaster, chosen for it's excellent blend of clarity and sustain, it has a light ash body, stock vintage Van Zandt pickups, stock wiring with volume and tone full up (to eliminate coloration), .010 gauge boomers, 18.6’ pro-co lifeline cord into the GT-100 head and matching 2 x 12 cabinet. (I mention all these things because they are factors that may one day prove my sanity) During the sampling the master tone settings were all at twelve o clock and it's a good idea to always start there when looking for your tone. The level settings are primarily for relative channel levels but do make a slight difference in tone. The recommended starting point is straight up.

The Vox type tone setting however, shows how the master tone section can be used to dial in the sound of different output/speaker configurations. Obviously, physics dictate that this can only be an approximation, but in terms of usable tone I believe you'll find that it's like splitting hairs.

Only much more fun!!
