It has the original \"check\" tag in the back also !  It's just had a service and is ready to go . Made in the USA - 60 Watt Tube Guitar Combo. 1 x 12’’.Sounds awesome! Pretty sure it has a replaced speaker ...long ago . Plenty of cosmetic wear -  Pictures help form decription . \u003c\/span\u003e\u003cbr\u003e\u003cspan\u003e‘’The S.O.B. was introduced in the Mark II era. This was Mesa\/Boogie's first attempt at having a reissue of the Mark I. It has 2 cascading gain inputs and its controls are Volume(gain) 1, Volume(gain) 2, Master, High, Middle, Low, Limit or Presence (depending on the version). No foot-switching available, however an A\/B splitter pedal can be used to select input 1 or input 2 separately.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThere was also a reverb option which replaced the Middle knob with the reverb control.’’\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThis particular unit features Limit (instead of Presence) and Spring Reverb (in place of a Middle EQ control).\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe Limit control essentially rolls back clean headroom and compresses it into Harmonic Gain, reducing volume while increasing distortion (very useful for low volume requirements). With the Limit set to ‘0’, the full 60 watts of clean tube headroom can be accessed. As the Limit control is turned toward ‘10’, the signal volume drops as distortion increases.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe Spring Reverb option sacrifices the middle EQ control leaving tone shaping to an dynamic interaction between the Treble and Bass controls (still very useable).\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThe preamp section is built on a solid single sided PCB, but the high-voltage\/power section is all point-to-point.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Mesa Boogie","offers":[{"title":"Default Title","offer_id":43951132147830,"sku":null,"price":1350.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0659\/1811\/files\/unnamed_8_098cf487-9d77-43fe-8603-3e73a9572754.jpg?v=1785982903","url":"https:\/\/musicatnoosa.com\/products\/mesa-boogie-son-of-boogie-1980s-amplifier","provider":"Music at Noosa","version":"1.0","type":"link"}
