I sold my GK212 combo in order to finance this Markbass Little Mark Vintage 1000 amp with a Markbass S58R 410 Pure 8 Ohms…WATT a World of difference (pardon me the pun)! What a sound, finally my Sire Marcus Miller P7 lefty 5-String sounds like it has meant to be, even in flat, mixed or old-modus, a Markbass footswitch enables to put the amp on mute or to alter between EQ’s…from slap to old school, this amp has it all! Definitly the best amp I’ve ever used, and so light (3 kg.) in a padded amp bag! The cabinet only weighs 16,4 kg and a golden tip: purchase a Stanley 2-1 folding truck and you will roll to any venue wit ease!
