Up for sale is a widely regarded industry standard: the Wampler Ego Compressor V2. This pedal is in excellent condition and has been well-maintained on a smoke-free pedalboard. 
The Ego Compressor is famous for its  Blend control, allowing you to mix your dry signal back in for parallel compression. This keeps your note attack crisp while providing that lush, "always-on" sustain that Wampler is known for. 
Key Features:

• Five Controls: Volume, Sustain, Attack, Tone, and Blend for total dynamic control. 
• Tone Knob: Meticulously tuned to add clarity and sparkle back to your signal. 
• Parallel Compression: Blend in the dry signal for natural-sounding dynamics. 
• V2 Upgrades: Top-mounted jacks for better pedalboard real estate and relay-based true bypass for silent switching. 
• Power: Standard 9V-18V DC center-negative power (can also run on a 9V battery).

Fully functional with no cosmetic wear. No original box included
