Sorry, but this item is out of stock and has been discontinued by the manufacturer. The perfect practice and rehearsal lead guitar amp. The K20 has both preamp and master volumes with a footswitchable, tube-style overdrive. Separate bass, mid-range and treble controls give the K20 a warmth and depth far beyond anything youšve come to expect from a compact amp. 15 watts of RMS power is controlled by 3-band equalization and drives the special 8"" Vintage Rock speaker.
