Hi guys. A guy on local buy/sell has posted a 1976 Marshall 4x12 (Blackback Pre-Rola Celestion G12H-30 16ohm 55hz) with small checker cloth. See below. https://www.kijiji.ca/v-amp-pedal/c...76/1362234730?enableSearchNavigationFlag=true He will only trade for a 1960ax/bx cab. I have a 1990' or so 1960bx with UK Greenbacks in MINT condition. Any thoughts on amp/trade value and this trade in general? I really like the looks of vintage Marshall's especially this 1976 one!
