Koch LB-120 II 4-Ohm Load Box


Innovative, ruggedly built and bursting with features, the Koch Load Box is the guitar player's tool.

Are you looking for an addition to your tube amp? Is the volume level of your favorite all-tube amp too loud? Do you want to get rid of those microphones in front of your speakers?

The Koch LB120 LoadBox II can reduce your tube amp's output power to small-club rehearsal or even to bedroom level. Koch understands that your tone is important and therefore the Koch Loadbox II has a specially designed circuitry which assures that your amp's tone will remain the same on all different power levels.

Koch has also added some smart features to improve your guitar sound live or in the recording studio. Finally, Koch has created an output in which the sound is simulated coming from a speaker and picked up by a microphone in front of it. No hassling with microphones anymore. Just Plug and Play!
