We just noticed some that the graphic/silk screening is a little off. Fully tested and 100% perfect otherwise. I didn't feel right trying to sell it on our site as 'perfect'.
MASS 100w Attenuator
This comes with the Headphone Tap Option AND Footswitch Option --- $60 retail options....
Designed for use with 60w amplifiers and lower. If you have a Tweed Bassman or Super Reverb, this is the one y0u want.
This attenuator has a main volume knob and 3-position treble compensation switch which affect the signal to the speaker. It also has a 3-band tone stack and volume control for the line out signal only.
Impedance selector for 2, 4, 8, 16 ohms, 0, 3db, and 6db treble boost, MASS bypass switch, unbalanced line out, tone stack for line out, tone stack bypass, extra output jack, range switch. The MASS employs an actual speaker motor for the load to yield a realistic interaction between the attenuator and the output circuit of the amp. The attenuation is continuously adjustable from -3dB to over -70db using the speaker control and the range switch.
By turning the speaker control to minimum (maximum attenuation), the unit may be used as a dummy load for testing or for DI use.
