The best sounding electric bass ever, IMHO, was Phil Lesh, with each of his 4 (sometimes 5) string pickups channeled through a dedicated channel of McIntosh amps, with multiple sets of JBL speakers for each string and pickup. Woofer movement from one pickup channel did not affect another channel, avoiding all intermodulation distortion. From 32 to 48 300 watt solid state and 350 watt tube amps were used for the complete 11 channel sound system, depending on both venue, and our failing memories. Check it out by googling Dead Wall of Sound, then click images. Interestingly, two of the designers were Owlsey Stanley, of LSD fame, and John Curl of Alembic and Mark Levinson fame. (The JC in ML model numbers.)
