Why should touring artists have all the fun? With the SV20H you can harness the formidable tone of the 1959SLP at home or in the studio. Switch between 20W and 5W at the flick of a switch and let the defining sound of the plexi live on.

In true plexi style, the SV20H features four separate guitar inputs, two for each channel. This gives you the ability to choose between the brightness of the high treble channel, the roundness of the normal channel, or blend between the two with a patch cable. Add in the EQ and presence controls and you can take your sound from warm saturated blues to aggressive biting leads. The power reduction featurealso makes it versatile enough for studio recording and home practice.
