3 in the last 9 months. 5 total. 4 times on tour. Always a different speaker. The 10"/32ohm replacements are impossible to find offline. Here's the setup: Fender Standard Jazz Bass (Stock pickups) into Sunn 1200s (1200 watt solid state/tube blend) into Ampeg SVT810 (32 ohm speakers wired in series for 4 ohms) No pedals or effects. Sounds amazing 99% of the time. Is my head just a speaker assassin? Could it be something wrong with my cab?
