The music retailer i work for had a Marshall roadshow last night.We had the Marshall band doing 2, 1/2 hours sets and talking about the amps.Chris George the Marshall demonstrator has a Nailbomb in the bridge of his Gibson Les Paul and it sounded awesome,very warm and toneful with great clarity.It sounded the best though through the 1959 head and a 8x12 cab (yes 8x12 cab).We had to carry it in.Heavy!!
