Here are the model details, I found the amp on the net:
Hangzhou Yiwei Electronic Audio Equipment
Speaker: 4*12”celestion speakers
Functions: Reverb, Volume control, Treble middle bass, Channel select, Overdrive channel (treble, middle, bass), Gain, Send and return level, Foot switch (effects/reverb), Impedance selector, loudspeaker output, Ground/lift switch and so on.
Dimension: Head 77.5*36.5*35.5CM, Cabinet 84.5*44.5*85.5CM
The guys in the shop may not have understood the amp'd details correctly - the webpage states celestion speakers but not what type. I also didnt notice reverb on the amp in the store but I could have missed that knob (or it was translated wrongly LOL)
