All I did was wash forty years of dirt and smoke off of it. So it was obviously originally built this way. I found that there’s a groove cut in the threads (of the switch) that lines up with a point on the face plate. I wanted to see if I could easily flip that switch (while I had access to the inside). You have to turn it to “off” to turn it on. ? One weird thing is that the power switch is 180 degrees out. I love seeing that hand wired, point to point electronics. When I got it home, I thought that I would like to clean it up a little, but retain it’s awesome “patina.” I took everything apart, just leaving the speakers in the cabinet. It wasn’t long until I realized that I just couldn’t get it out of my mind. I loved the sound but didn’t pull the trigger right away. It looked very rough as only an amp that has seen a lot of use can look. Someone tried to replace the grill cloth but didn’t get it tight enough. I just got one of these great amps! I found it at a GC a couple of weeks ago looking very used, with ripped tolex and marks all around the normal and bass #1 inputs. The ultralinear circuit also has one less tone control on the bass channel.įrom ’72-’76 Fender also produced the Bassman 50 head (50 watts), and the Bassman 70 head until the end of the run. This is unlike the Super Reverb, which uses 8 ohm speakers for a 2-ohm load.

These models use different speakers – 16 ohm speakers wired in parallel (NOT series as noted earlier – that would result in a 64 ohm load and an extreme load on the output transformer) for a 4-ohm load.
The ’77-80 silverface and ’81/82 blackface amps use an ultra linear output transformer, hitting the tubes with much higher plate voltages and pumping out up to 70 watts.

It may be imperceptible, and with some preamp mods may work that way as a guitar amp (much less so as a bass amp except as a low-volume studio amp) The output transformer will handle a 4-ohm load, but it will result in slightly less power due to the impedance mismatch. The (roughly) 50 watt silverface version of the Bassman 10 had four 32-ohm speakers wired in parallel for an 8-ohm load.

Both the Tube Driver and the TD-X are fantastic pedals. They also have more headroom and less compression. In my opinion the TD-X doesn't quite get the high gain magic of the Tube driver, but I'm being picky to make a comparison. I really like the TD-X.not quite as much as the real thing but they sound great, are a reasonable size, and take a standard 9v plug.
The down side is that they take a tube and a standard plug so I also own two Buffalo FX TD-X's that live on a smaller board and I use when it isn't practical to bring my Butlers.

I found that I liked it for both my high gain and my low gain and bought a second one so my board has two 911 tube drivers on it.one for high gain and one for low.
Finally I broke down and bought a 911 Tube driver. I tried all the options that you'd expect. I tried to find a BK Butler Tube driver sound on a budget for years.
