The UK-made SV20H lets you 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. 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.
