Strengths
- The famous trick of simultaneously boosting and cutting the same low frequency creates a uniquely musical, non-additive tone shape
- Passive tube design imparts a warm, gentle harmonic saturation many active EQs can't replicate
- Became a mastering and mix-bus staple still referenced by virtually every EQ plugin emulation since
Trade-offs
- Passive circuit needs a healthy input/output gain stage around it, so it's rarely used alone
- Original transformers and tube sockets require careful, specialist maintenance to preserve their character
