POWER AMP:
Two Svetlana EL34�s in combination with a high quality output transformer build to vintage specs, provides an excellent sounding classic power station.
CLEAN CHANNEL:
This is "classic" channel, standard in all models, it�s warm, sparkling and full of tone combined with a superior headroom. It�s the channel where it all starts.
POST-EQ OVERDRIVE / HIGH GAIN CHANNEL
This amazingly flexible channel allows you to create tones ranging from compressed clean, to raw crunch and even to mega-distortion. The specially designed 'Dual-Drive' control provides this enormous range of tones by controling the gain of two preamp stages simultaneously. Accurate voicing in the preamp stages in combination withclassic post-distortion tone control enables this channel to produce the right sound in every gain setting.
SERIAL EFFECTS LOOP
This loop, including buffered in- and outputs, operates at -10dBV signal level and therefore allowing you to use any effect unit you want, from an antique stomp box to a professional 19 inch rack unit.
HEADPHONE AND RECORDING OUTPUTS
Special designed speaker-simulating filters ensure that the sound is identical to the sound coming from the speaker.
AUTO POWER-SOAK
This built-in 50W speaker replacer is at your disposal 24 hours a day. Even in the middle of the night it allows you to play the solo you have just been dreaming of with full tube-power without waking up anyone. Just pull the speaker plug (the power soak now connects automatically) and the amp can be driven at full power without any danger of damaging vital parts. You can also use the power-soak as a "second" speaker and reduce the power to 25W.
SPRING REVERB
The built-in original spring reverb tank causes the amp to expand with a great range of vintage reverb textures.
