Description Product Description The Astoria Custom from Marshall is for tone seekers who want it vintage but with the convenience of contemporary features, such as: valve driven true bypass footswitchable FX Loop and independent Loop Level control, with added tonal shaping and footswitchable gain Boost. The Body feature adds 'girth' to your sound for chunkier riffing. It works by adding a +8dB shelved low frequency boost from 120Hz downwards.
