The all-tube Marshall 1959SLPX Amp Head gives guitarists absolutely gorgeous vintage over-driven tone, perfect for lead distortion, while still offering responsive, tight growl, offering a perfectly matched tone, just like the sounds that were created by the original 1967 to 1969 models. Pete Townshend's addiction for volume saw this Amp Head boast 100 Watts of power that is provided by four EL34s and three ECC83s found in the preamp to the exact configuration as the original. Also featuring True bypass series FX loop, 3-band EQ, and presence control all go hand in hand to make the Marshall Vintage Reissue 1959SLP 100W Guitar Valve Amp Head a must-have.
