rpb 19/37


As you may have seen on my web site, the SJT 37 had been pulled for redesign. It was basically the FTR with a 2 tube back end (EL34's). And although it had its own sound, people went for the FTR because it went to half power, had more features, etc. Well, it's back.

I am now proud to announce that the SJT 37 has been re-released as the RPB 19/37. Like the JRT 9/15, the RPB 19/37 has 2 sets of power tubes that you can switch between via the toggle in front, producing 19 watts with 2 6V6 GTs and 37 watts with 2 EL34s. It has all the same sounds and features as the original SJT 37 but with the added feature of a lower power amp WITH IT'S OWN SOUND, more like the FTR 37 in half power. So it is truly like having two amps in one.
