2012 Yamaha – AC4K Prototype – with System 63 SRT Preamp – ID 5080

The Canadian guitarist and songwriter Dave Goodman got this unique piece about 11 years ago from Yamaha.
The stereo circuit allows the SRT sound to be combined with a passive magnetic PU - ideal for studio or live setups.
With a mono cable, the output jack works normally with the Yamaha SRT pickup.
