Hi. I'm thinking of modifying my Marshall 1936 cab. 212 Cab with Celestion G12T-75 and Vintage speakers. I'm thinking of converting the cab to a semi-open one similar to the one in the picture below. Anyone ever done this? The reason is to get a bit more sound dispersion on stage without loosing too much of the "bigger sound"(best way I can describe it). The head is jvm410hjs. I have also acquired a laney lionheart 20w head recently. Style of play is clean (like in jazz clean), blues and fusion/rock.
