The Shop’s Take (TL;DR)
Here is a Fulltone Distortion Pro DP-1 in Good used condition. The Distortion Pro is a highly tweakable analog distortion designed for players who want more control than a typical three-knob drive pedal provides. With separate controls for Resonance, Voicing, Highs, and Saturation in addition to Volume and Distortion, it can move from tighter classic-rock crunch into thicker, smoother, more compressed lead tones. This example shows some cosmetic wear and a couple of small hardware issues, all clearly noted below, but remains fully functional.

Full Description
The Fulltone Distortion Pro DP-1 is one of the more flexible distortion pedals from Fulltone’s earlier catalog.

Rather than giving you a fixed EQ voice with only a basic tone control, the Distortion Pro provides six interactive controls:

• Volume sets overall output level
• Distortion controls the amount of clipping and gain
• Resonance shapes the low end
• Voicing shifts the midrange emphasis
• Highs adjusts upper-frequency content
• Saturation changes the amount of compression, sag, and overall feel

The interaction between these controls is where the pedal becomes interesting. Resonance can add weight and low-end authority, while Voicing lets you move the focus of the distortion through different parts of the midrange. Saturation affects more than just gain, changing how soft or immediate the attack feels and how compressed the distortion becomes.
That makes the Distortion Pro less of a “set it once and forget it” pedal and more of a shaping tool for dialing the distortion around a particular guitar and amplifier.
The pedal also includes two internal trim controls for additional gain and overall midrange/distortion adjustment. These are factory-set and generally best left alone unless you specifically want to fine-tune the pedal beyond the external controls.
This example is fully functional and has been tested.

Condition
Good used condition.
The pedal shows normal cosmetic wear from use.
Two control knobs have small chips. These are cosmetic and do not affect operation.
The right-side battery compartment screw is missing its internal retaining nut. The screw itself is a common hardware type and the missing nut should be straightforward to replace if desired.
The pedal remains fully functional.
Please review all photographs carefully, as they show the actual pedal being offered and are an important part of the condition description.
