The TH100 has exactly the same controls and pre-amp section as its smaller sibling, but when running in class AB1 (half power) it makes 35 watts on two output tubes and 70 watts on four output tubes, says the company. Put it to full power (AB2 position) and the amp makes 50 watts with two output tubes and 100 watts with four. Being able to switch to half power means you can reduce the listening volume while preserving the power tube distortion.
Just like the TH30, the TH100's design features the best of the Rocker and TH Series, with two channels.
The new head will come with four EL34 tubes, four 12AX7 pre-amp tubes and a 12AT7 for the low impedance FX loop. It will also have four internal bias pots so the output tubes can be matched into the amp by a qualified technician. In terms of size and weight it will be comparable to the Rockerverb 100.
