The Divided by 13 SJT 10/210 head is similar to the FTR 37, another popular Divided by 13 amp. However, it’s slightly modified, has less wattage and a few exclusive features that make it of definite interest. It runs in either a 10 watt Hard Class A mode or a 20 watt Class AB1/A mode, depending on your preference. You can get a great 50’s style Tweed sound from 10 watt mode, which some players really love. The SJT 10/20 can access both channels via its two input jacks. In addition to these channels, you also have a dampening/flattening switch and a mid/gain boost. The SJT 10/20 head is quite versatile and is a great way of filling that 10/20 watt slot in your amp arsenal.
The first channel on this head features volume, treble, bass, and reverb. Channel 2 has its own volume control. The SJT 10/20 uses 12AX7 tubes for its preamp section and four 6V6GT tubes in the power section. For its rectifier tube, the SJT 10/20 uses either a 5AR4 or a GZ34. The head weighs 32 pounds, while the combo is 50 pounds. Both are suitable for taking to gigs or for using in the studio. The SJT 10/20 head retails for $2,300.
