02Pickups

Ceramic Open-Coil Humbuckers · IncludedA matched 7-string set, voiced to keep the extended range clear. Ceramic magnets keep the low string tight and defined, whether it's the C2 in SieteQuinto tuning or the B1 in standard, while the high strings stay focused and articulate.

Bridge: wound hot, about 19.6 kΩ, for drive, sustain and a strong attack
Neck: wound lighter, about 10 kΩ, for a warmer, rounder voice
Wax-potted against microphonic squeal at stage volume
Four-conductor wiring, so the pickups can be rewired later
Pole spacing matched to each position: 61 mm bridge, 57.5 mm neck

Fitted, wired and set up by hand for your chosen voicing and tuning, because every E75 is made to order.Made by Wilkinson.Alnico V Vintage-Voiced Humbuckers · +$250A classic PAF-style 7-string set. Alnico V magnets give a warmer, more open voice than ceramic, with smooth sustain, rounded mids and a clear top end, suited to jazz, blues and clean or edge-of-breakup tones.

Bridge: about 9.4 kΩ, airy and bright with a slightly compressed, singing feel
Neck: about 8.6 kΩ, warm and full with a lightly scooped midrange and clear attack
Vacuum wax-potted, so they stay quiet at stage volume
Four-conductor wiring, so the pickups can be rewired later
Hand-built in California

Fitted, wired and set up by hand for your chosen voicing and tuning, because every E75 is made to order.Made by Seymour Duncan.

03Bench voicingSet automatically by model

Warm Jazz Voicing · LZR · set at the bench

Set by model

The LZR is voiced warm. 250 kΩ pots take a little of the edge off the humbuckers' top end, giving rounder cleans, smooth leads and a tone control that rolls off gently instead of going muddy.

250 kΩ full-size pots with split brass shafts, for a warm, balanced voice and a smooth taper
0.022 µF tone capacitor, for a usable sweep from bright to mellow
3-way blade switch: neck, both, bridge
Volume and tone controls with knurled knobs on a solid, pre-wired control plate
¼" output jack

Wired, tested and set up at the bench for your tuning, because every E75 is made to order.
