Cultivated 68' Plexi tone by Kool & Elfring

Channel 1 'Mild mode' is more clean with tighter bass response

The sounds of channel 1 'Mild mode' are best described as dynamic, three-dimensional, open and sparkling. Its warm yet with good definition. The gain setting starts at splendidly sparkling and dynamically clean. Beyond one o'clock the clean morphs into a clean sound with sweetly organic edge of breakup. Around three o'clock very gradually the sound changes into a sweet and subtle 3D crunch.

Channel 1 'Hot mode' Is hotter with fatter bass response

The 'Hot mode' is close to the original Plexis sound and feel that we've all grown so familiar with. The sound breaths, its three-dimensional and open sounding with spongy bass response, very fat mids and those rich halo-kind of high frequencies that fade away just before becoming to harsh or brittle. Just like the original this amp is super dynamically. Even with the gain at full you're still able to clean up the tone by soft attack on the strings or turning back the volume knob on your guitar. Turning up the the guitars volume knob and hitting the strings hard will give you that that briliant complex saturation whichmakes Plexi tone so unique.

Channel 2 : Overdrive / Hotrodded Plexi

Mode 2 boosts the Plexi-tone into sweet, tonesoaked overdrive. Extra gain stages are added to the internal circuitry resulting in a more compressed tone with endless sustain. The overall Plexi feel is still there just fatter and hotter!
