I know using guitar heads for bass is nothing new, and it's been discussed in these forums in the past, but I thought I'd share my story. The singer in my band, who also plays guitar picked up a Laney Linebacker 100w reverb head, and Laney 412 cab. He really only wanted the cab, to play with his Marshall head, but the Laney head was a throw-in when he bought it. For months, this Laney head has sat on a shelf in our rehearsal space, having never been played once. For fun, I grabbed it, and put it on top of my Ampeg 810av cab, plugged it in and did a bit of tweaking. To my surprise, it sounded awesome. It was punchy, beefy and I could get a great clean sound, while adding as much dirt as I could handle. Volume wise, it held up with the band well. We play hard rock / metal, and it was good. There would be a concern about headroom if I were playing a larger venue with no p.a. support, but that really doesn't happen. Although, it wont replace my Ampeg head, I may give this thing a shot at my next gig. Thanks for reading.
