The Goldtone GA-15 is a late-1990s Gibson amp designed and built by Trace Elliot. It is not related to the 1950s 6V6-powered GA-15. It has a single ECC83 preamp channel with volume, bright and tone controls, and an ECC83 long-tail inverter driving two EL84s in class A for 15 watts of chimey, touch-sensitive tone.
