Mark at Crash Magnetic Transducers owns this beautiful '77 SF Bassman 100 head. He's pulled two of the output valves (5881 in this case) and it now runs at 50w RMS. It's all original except for a cap-job done by myself March 2014.
If you want to pull 2 tubes in your own amp, then you'll also need to connect an 8ohm cabinet instead of the usual 4ohm.
The Gibson Les Paul is fitted with CMT's Saltbuckers (great sounding PAFs) and is played by Aynsley Lister - www.aynsleylister.co.uk
