Omschrijving
In classic cooking tradition, the big brother of the Studiotone 20 Combo sounds much bigger and has more features than you would expect from its small appearance. Starting with four Class A EL84 power amplifier tubes, a redesigned speaker and cabinet, three foot-switchable channels and two powerful voicing switches, the Koch Studiotone XL sound is reminiscent of the British tube amplifiers of the 60s. The three channels (Clean, Overdrive & Overdrive+, all with their own volume control) take you from round, warm tones to rich EL84 overdrive & compression. The 2-way "Mid Shift" switch allows you to raise the mid-range frequencies by 800 Hz and the 3-way "Bright" switch allows you to lower or amplify the high frequencies to fine-tune the upper end. However, some of the big surprises are left for the rear, and a quick inspection reveals a serial effects loop, a recording output with microphone placement and cabinet-style simulators, two line outputs (one unfiltered and one low level) and a "headphone out" jack. 4, 8, and 16 ohm speaker outputs allow for any combination of speakers, and the built-in Power Soak and speaker on/off switch allow the amplifier to play while the speaker is off for recording or headphones.
