KOCH STUDIOTONE 20 COMBO

Don’t let its size fool you. The Koch Studiotone may look like a modest compact combo, but it’s a Class A powerhouse packed with more features than amps twice its size.
Driven by two EL84 tubes, this amp delivers everything from warm 60s British cleans to saturated, high-gain overdrive. Between its custom-designed speaker, three footswitchable channels, and a "Mid Shift" boost, the tonal flexibility is immense. Flip to the back, and you’ll find a professional toolkit including a recording output with cab simulation, a built-in Power Soak for silent tracking, and a serial effects loop.
It’s a world-class studio and stage rig disguised as a grab-and-go combo.

from 6 to 2 watts

Pure Saturation: With 6 watts of pure Class-A output, the amp offers instant dynamic response. Switch the toggle to 2 watts to achieve rich power-tube saturation at lower volume levels.

The Interface: pre CONTROL

Gain, Tone & Volume: From sparkling cleans to that legendary "Tweed" growl. Dial in your base character with the Gain and Tone controls, then use the Master Volume to push the power tube into sweet, singing sustain at any level.

10" Jensen Falcon

We paired the Durango 6 with the 10-inch Jensen Falcon for its warm, organic character. It delivers a full-bodied low end and silky-smooth highs, perfectly capturing the harmonically rich response of a classic Class-A circuit.
