(Black/chrome) 2005 - Working Pro combos replace the Workingman's combos.(Black/chrome) Please note: The following "Vintage" models are completely sold out and SWR no longer stocks the parts required to build them.For some reason the ability to get all the boom of the big rigs into a small package has escaped some builders.Granted, the legendary Ampeg B-15 “fliptop” may be an exception but it was still not designed to cover all musical situations. Rabe introduced an amp that would revolutionize the bass world with its good amount of power and full range sound.Setting the switch to the (right) "OFF" position defeats the tweeter (removes the tweeter from the circuit).Tweeter Protection Circuit The Workingman's 4X10T does not contain a protection circuit for the tweeter.The amp was the Redhead and it set the mood for a great line of combo amps to come.
