Underhill MC4-B-SPPP Series Comped by Turner Pickups published on 2023-04-04T16:19:48Z Simple clip running though the various filter settings on an Underhill filter preamp... All sounds coming from an SBMM Ray4 with a single Turner Pickups MC4-B-SPPP pickup in series mode, in the typical MM position. First half is LPF only, turning down in increments. Then, HPF (Treble Filter) is engaged while filter turned back up in increments. Please excuse the fret buzz ;-)... I installed some new lighter gauge strings, and had not yet done a complete setup to compensate. Signal chain: Bass -> Axe I/O Solo -> Amplitube Bass 1 Complete Rig -> T-Racks White 2A compressor
