Pickup interaction: Augment layer
The middle pickup is added after the humbucker selection to tighten lows and sharpen attack.
What it is
Relay Current is a rhythm-first model built around attack, low-end control, and mix clarity. The main guitar is a standard bridge/neck humbucker layout. The middle pickup is added separately when you want the sound to get tighter and more focused.
Pickup interaction
Category: Augment layer.
The 3-way selector chooses the normal humbucker voices. The middle pickup is added with the push-push volume control as an independent layer. It is not meant to be louder than the base sound, and it is not treated as a destination voice on the selector.
That matters because Current is not about more output. The middle layer changes the shape of the sound: tighter lows, stronger upper mids, and faster attack.

How it behaves
With the middle layer off, Current behaves like a clean two-humbucker guitar with a clear bridge and a slightly lower-output neck. That keeps the basic controls familiar.
With the middle layer on, the guitar gets sharper without getting bigger. The low end tightens, the front of the note gets quicker, and the upper mids sit more clearly in a band mix. It should feel like the same part became easier to place, not like you stepped on a boost.
Choose Current if your main problem is fitting into a groove without disappearing or getting woolly.
Who it's for
Funk, pop, and tight rhythm players. Current is for parts where timing, attack, and mix position matter more than warmth or sustain.
Pickup choices
- Neck: GFS Vintage 59 Humbucker
- Middle: GFS Retrotron Hot Nashville
- Bridge: GFS Professional Series Alnico V HOT Humbucker
If you substitute parts, use a medium-output Alnico V bridge pickup around 9-11K and a clear, slightly lower-output neck. The middle pickup is critical: it should be focused, mid-forward, and fast. Avoid warm, scooped, or soft-attack middle pickups because they work against the model.
