Bass - Double bass
He has ZAMed :
A YAMAHA TRB5IIP bass
( Unmodified in 9 volts )

I use the ZAM on tour with a TRB5IIP Yamaha and a Silent Bass SLB200. The ZAM is extremely convenient as it eliminates the need for batteries, but it also gives me a perfectly balanced and straight sound over the full range.

No more whining sounds !
