My main bass is a lovely restored Hawkes Concert from the early 1900s. Complete with a room rattling low C extension courtesy of Sam Wells. I also have a more recent Jay Haide Panormo as backup.
I have a few bows (mainly french pattern at the moment), including Lamy, Doerfler, Knoll and a rare english J Horsfall. The Lamy belonged to my teacher, and was featured in the film of Fiddler on the Roof (along with many west end shows!)
In addition to several Overwaters (4 and 5 string J basses and Progress models) I also collect vintage/unusual instruments. Favourite are two Squier JV series jazz basses from 1982/3 (one being the rare early 'fender logo').
Having tried a LOT of amps over the years, I now mainly use two Barefaced cabs (super light & hand-built in Brighton by Alex Caber) along with Markbass and TC Electronic heads. I also have several Schertler and SR Technology combos for double bass set ups (to go with my Schertler pickups)
Although I tend to avoid more than basic effects & outboard gear, I do have a variety of Boss chorus/octaver pedals, a Visual Volume pedal and Sansamp DI
For gigs and PA reinforcement I mainly use SR Technology active speakers plus an HK Elias PX rig (depending on the venue). SR gear is almost unkown in the UK but VERY clear, hi-fi sounding gear (they've made many of Schertler's amps for years) which is especially good for choirs and acoustic. And they go LOUD! I also have several mixing desks (including a 32 channel GB2) and a variety of pro microphones.
