About KOCH Studiotone 20

Because the Koch Studiotone 20 20W Combo Amplifier with 1x12" Speaker is more than just a compact combo, it stands out in the crowd of musical equipment. This powerful, high-quality amplifier is a testament to Koch's tradition of delivering superior sound in a compact package. Equipped with two EL84 power tubes in Class A, a newly designed speaker, and a robust cabinet, this amplifier produces a sound reminiscent of the iconic British valve amps of the 60s.

The Studiotone 20 20W Combo Amplifier is versatile and reliable, offering three foot-switchable channels - Clean, Overdrive, and Overdrive+. These channels allow you to transition smoothly from round, warm tones to saturated EL84 overdrive and compression, catering to a wide range of musical styles and preferences.

The amplifier's 2-way 'Mid Shift' enhances the mid frequencies around 800 Hz, while the 3-way 'Bright' switch provides the flexibility to cut or boost the high frequencies, enabling fine-tuning of the top-end sound.

The back panel of this durable amplifier holds more surprises, featuring a serial effects loop, a recording output with microphone placement, and cabinet-style simulators. It also includes two line outputs - one unfiltered and one low level, and a 'Headphone Out' jack for private practice or recording sessions.

The Koch Studiotone 20 20W Combo Amplifier is compatible with 4, 8, and 16 Ohm speakers, allowing for a variety of speaker combinations. The built-in Power Soak and Speaker on/off switch offer the convenience of playing the amp with the speaker turned off for recording or headphone use.

Adding to its versatility, this amplifier also houses a short scale spring reverb tank with a front-mounted level adjustment. With its impressive features and compact design, the Koch Studiotone 20 20W Combo Amplifier with 1x12" Speaker is one of the most versatile and compact guitar amplifiers available in the market today.
