The TB-15 is Moog's purpose-built companion amp for the Etherwave Theremin — though it works equally well as a compact keyboard or synth practice amp. Fifteen watts through a heavy-duty 8-inch speaker, two independent inputs with individual level control, a 3-band EQ for tone shaping, and a 1/4" headphone output. It's a straightforward, well-made little combo that does exactly what it's meant to do: give the Etherwave a proper voice in a room without a lot of fuss. Compact, lightweight, and easy to move around. Discontinued and not always easy to find.
This unit is in very good condition and fully functional throughout.
