The AMZ DS1 Fat two-resistor mod

This is a mod from AMZ by Jack Orman. It’s a simple 2-resistor change that will bring the gain of the pedal down into proper distortion range & get it out of the fizzy fuzzy territory.

It’s a simple mod that really changes the way the pedal sounds by taking away the amount of distortion available, so the pedal goes from extreme to moderate. This mod also increases bass response a fair bit and its really noticeable. For my likings it brings the gain down two much, however the pedal does sound really different and it’s more dynamic and less compressed. As the mod states, you get more of a general distorted sound and much less of the fizzy fuzz territory sound from the stock DS1.

The mod gives a more desirable & defined distorted tone but I would like it to have more distortion available. Being such an easy mod, it’s worth a shot and can be used in conjunction with other mods, as most of the DS1 mods out there do not require you to change the same two resistors as the AMZ mod does.

After playing around with this mod for a day or so I change it back to the stock values as the reduction in available distortion was to low for my need.

If you use this mod and like it please give credit to Jack on his website as he give us an excellent source for mods, schematics & general DIY Pedal information. You can find his website and direct link to the mod at the links below,
