This page includes sound samples used in a listening test for several neural network based guitar amplifier models. Two guitar amplifiers were modelled: the Blackstar HT-5 Metal guitar amplifier (with gain set to '10') and the Mesa Boogie 550 (on the 'Crunch' channel, gain set to '3'). Unprocessed input samples are shown in the 1st column, along with those samples after processing by the target guitar amplifier (in the second column), and by each of the neural networks included in the listening tests.
