This Lab Series advert featuring bluesman B.B. King and his L5 appeared in Guitar Player magazine in May and August 1981 - just one of many 'artist' adverts for the amp line. King's bassplayer, Joe Turner, had previously appeared in a Lab Series advert with the 200w L4 bass stack. Many Lab Series ads contained suggested settings... and this one is totally B.B.
Not many artists are on the road as much as the great King of Blues. That's why B.B. travels with a Lab Series. He needs an amp that can stand up to a rough ride and still stand out on stage. Night, after night, after night. Lab Series is built to do exactly that with solid pine sides, road rugged electronics and more secure speakers than other amps.
But there's a lot more to Lab Series than meets the street. Inside is advanced circuitry that gives every Lab amplifier sound capability beyond its size. And, Lab engineers have designed more flexibility into fewer controls. So you get all the range you need, from pure clarity to hot distortion. And overdrive without overload. You can change your picking attack, add sustain or acoustic flavour. It's the kind of tone control every musician wants. Whether you're crying the blues, or playing your own favourite colour.
Lab series. Amps that are built to take it. Take it from B.B. King.
