Basses:
My first Warwick, a JD Thumb, which I've had since 1988. I don't really use it since moving to 5-strings but I wouldn't sell it.
My first Antoniotsai bass, the first 5-string I've had that felt as good to me as the Warwick
My first and second Sei headless basses, an Original fretless and Flamboyant fretted, which are also lovely to play
Other:
Eko Ranger VI which I bought in the 1980s - my noodling around at home guitar
Zoom MS-60B which is my swiss army knife pedal
