The Blackstar Artisan 30H is a guitar amp head that is deceptively simple in operation and yet highly flexible in functionality and tone—In keeping with its classic design, With the emphasis on simplicity and sonic purity, every feature of the Blackstar Artisan 30H amplifier head has been refined to provide you with the widest range of reference vintage tones. That's because the electronic circuitry works in harmony with the finest components and materials available.The Artisan 30H is a guitar amp built to last a lifetime. The 30W amp head effortlessly combines vintage style and rugged, road tested reliability. The point-to-point tag board construction, welded steel chassis and finger-jointed birch-ply cabinet are complemented by beautiful vintage red Tolex and etched aluminum panels. Power AmplifierThe Blackstar Artisan 30H power amplifier uses 4 EL84 power pentode tubes in Class A bias. The EL84s used are graded in terms of quiescent operating point and transconductance, to give you excellent hum performance and dynamic feel. The Blackstar Artisan 30H power amplifier operates in 2 modes, namely push-pull (30W) or single-ended (10W), depending on the setting of the power amplifier mode control. This control is designed to maintain the optimum operating point in both single-ended and push-pull modes to ensure maximum performance.In push-pull mode the power amplifier takes on characteristics similar to that of a Class A early '60s British amplifier. The single-ended mode allows the generation of the critical power amplifier harmonic distortion at a much lower volume. The lower power setting is particularly effective for home and studio use.A cathode-coupled phase splitter enhances the power amplifier and provides balance in the power amplifier drive as well as superb dynamic response. In keeping with the vintage sonic signature of the Blackstar Artisan 30H, the use of a tube rectifier adds compression to the power amplifier response and is critical in g
