i am selling an swr 350x bass head in good shape, has been used for up to 40 gigs as well as in studio without any problem. it weights +/-10 kgs. it has a tube preamp, an integrated octaver fx (subwave) . it's equipped with all modern connexionx: fx loop in/out, preamp out, power amp in,etc. it can be connected with speaker cabs by jack or speakon cable. this head is very reliable , sounds very good and has been recently revised by a technician. the box is a 1x15" + horn cab in very good shape, it has only been used for 3 gigs and at house for practice.it delivers a massive punchy/chunky tone a is quite versatile for 1x15" cab. it can be used alone or in combination with another cab ( 4x10").
