Mike's "Moon Bass" is a 4 String Warwick Streamer built around 1990 with the for that time typical thinner body style, a PJ Pickup configuration with active EMGs, a brass Warwick Just-A-Nut, maple neck, maple body and a 34" scale. Two replicas with different finishes have been made by Warwick for Mike Inez in 2017/early 2018 featuring the exact measurements and the closest specs to the original which have been possible in 2017. 2 original bodies were used, which were made in the early 1990s and held on stock for exactly that purpose. You can find images and the exact specs for these two replicas under these links: warwick.de/en/Warwick---Products--Instruments--Customshop---Masterbuilt--Basic-Bass-Models--Streamer--Streamer-Stage-I--Streamer-Stage-I-4-String--Streamer-Stage-I---18-3793--4-string--Pictures.html warwick.de/en/Warwick---Products--Instruments--Customshop---Masterbuilt--Basic-Bass-Models--Streamer--Streamer-Stage-I--Streamer-Stage-I-4-String--Streamer-Stage-I---18-3792--4-string--Pictures.html Hope we could help you.
