The Rikstone H30W is an A class head amplifier with cathode bias. The amplifier part is based on VOX AC30.
This amp has been developed in co-operation with
Hasse Walli.
Hasse Walli who is one of the top guitarist in Finland has helped me to find the original vintage sound for the amp. Big thanks to Hasse.
