The amp also features Power Reduction which can be accessed via the Master volume control, Edge control for controlling how dark or bright the overall tone is, and Sensitivity control to find that perfect bite.The Astoria Series is about pure, unfettered vintage tone from loud, unbroken clean to sublime saturation. Built for the connoisseur using precision point-to-point hand-wiring, Astoria is for the serious guitarist who craves authentic tone, but who also wants contemporary features. Astoria offers, across the series, footswitchable features such as: valve-driven FX Loop with independent level control, +20dB gain boost and dual channels, as well as tonal switching and modern power reduction.To achieve the innovative marriage of authentic tonal character and contemporary features, the Astoria Series uses turrets mounted on the PCB, allowing the hand-wiring and more complex switching circuitry to elegantly coexist on a single board. Please note: ALL of Astoria' tonal circuitry is point-to-point hand wired for quality and authenticity of tone.Astoria' all-tube heart consists of 12AX7 in the preamp, GZ34 rectification and KT66 output stage, which is cathode biased and has no negative feedback.The output and mains transformers are designed specifically for Astoria, and some of Astoria' pots use specially selected log tapers to be more balanced across their effective ranges.Astoria also features Hi & Lo inputs, with the Hi input providing an extra 6dB of sensitivity”a characteristic of many classic, vintage amplifiers.All three Astoria models are expertly crafted and are designed, engineered and constructed to the highest standards at the Marshall factory in Bletchley, England.
