From a guitarist point of view, in a class A amplifier each of the amplifiers power tubes are working at maximum output the whole time. This makes them run ‘HOT’ and generates a very natural level of smooth tube compression.
Higher powers are obtainable by using multiple valves in parallel – in this case 4 x EL84’s are run in Single ended mode and then paralleled up to give 20 watts RMS of Parallel Single Ended tone.
The G12H guitar speaker is hugely popular with players looking to recreate the classic sounds of 60s and 70s rock. With a strong, aggressive low-end and powerful low-mids, the G12H penetrates any mix with an attacking upper mid-range and an ice-cool top- end.
The Celestion Vintage 30 is an industry standard speaker used to capture many of the classic guitar performances. The Vintage 30 features detailed and complex overtones, a warm low-end, a famously rich vocal mid-range and a beautifully detailed top-end. Used singly to reveal the complexities in hand- wired boutique amps, or in quartets for a wonderfully intricate vintage 3D crunch.
