Here's a film of the production of Warwick Masterbuilt basses at Warwick's Custom Shop in Markneukirchen, Germany:
The bolt-on neck of this Streamer LX consists of wenge in three laminations, while the fingerboard is ziricote. 24 extra hard jumbo bronze frets were inserted into the fretboard using Invisible Fretwork Technology and set up by Plek Fretwork. Further details include a height-adjustable Just-A-Nut III brass nut, Warwick tuners with wooden knobs, active MEC P/J pickups, active Warwick 2-way electronics with a lithium battery that can be recharged via USB, a volume P/P control, balance, treble and bass, a 2-piece solid Warwick brass bridge, Warwick security locks and Warwick EMP strings (045" - 105"). Also included is a Warwick User Kit, a handcrafted leather bag, and a certificate of authenticity.
