Cur síos

The DSL20 Head is a two-channel valve amplifier head with Classic Gain and Ultra Gain channels, each with its own gain and volume controls. A channel select switch and a tone shift switch change between the voicings, and shared treble, middle, bass, presence and reverb controls shape the sound. Reverb is digital, and the head also has dedicated resonance and presence features.

The power stage uses two EL34 valves and is rated at 20W. A switch lowers the output to 10W for quieter playing at home. The preamp uses two ECC83 valves, with a further ECC83 as the phase splitter. A single series effects loop is fitted.

There are three 1/4" speaker outputs for 16Ω or 8Ω loads and a 3.5mm emulated line output for recording. Inputs are a 1/4" instrument jack and a 3.5mm jack that serves as aux in and footswitch connection. The unit weighs 9.7 kg and comes in black with a detachable power cable.
