Well, this was a fun project!😁   I fancied a cheap 1x15" to go with my Markbass LMII and Ashdown ABM Mini 15 practice rig, so kept my eyes peeled. I came across what was once a Trace Elliot combo in a very sorry state, but it was only £20, and I do LOVE a project!    I trimmed off the section where the amp used to be, flipped it on its side, plugged the old handle routs and speakon hole (installed by the previous owner), and sanded it all up.   Pai
