- v1: "triangle" Distortion-Free Guitar Sustainer;
- "Made in usa" on the right
- Seen in black, blue, red, violet and purple.
- "MADE IN NYC, USA" on the left, below "Electro-Harmonix".
- Seen in black, blue and red, never in violet and purple.
v2 and v3 also look different inside and sound very different: v2 is phatter and dirtier, v3 is more compressed and cleaner.
