I wanted to try out a 2×8 cab design as I had enjoyed playing my guitar through a Marble Blues Harp amp using these speakers. Also to give me a small easy to carry amp with some power. Like angle fronted cabs so gave this design an angled front. Really enjoyed this little project and the tone of the amp when cranked is very good and would give some tube amps a run for their money! Want to try her out with blues harp.
