Here’s a video demo I shot for G&L comparing their two P bass models, the SB-1 and LB-100. Both have P style pickups but the LB-100 has an Alnico magnetic pickup and the SB-1 has the G&L MFD, Magnetic Field Design, Pickup. Both sound great but they do have a tonal difference.
The basses were recorded direct out of the BBE B-MAX preamp.
Both basses were also recorded with their volume and tone knob turned up all of the way.
