The power of a Plexi in a new portable style. Now the legendary sound of the 1959SLP is yours for the taking, packaged in a 20W combo that you can enjoy at home or in the studio. It’s got the same vintage tones you know and love, just redesigned for the modern player.

Whether you’re looking for warm blues tones or punchy leads, the SV20C has all the same tonal options as the original 1959SLP. Choose between the high treble and normal channel, or find the perfect blend between the two using a patch cable. While its predecessor was built to get loud, the SV20C is equipped to handle those quieter environments with power reduction to 5W.
