This is an amazing Tube guitar combo made by Laney in England in the 80's. It uses 2x EL34 power tubes and 4x 12AX7 pre-amp tubes all through a single 12" speaker. It features 2 inputs (high, low), 2 channels with separate gain knobs ( one knob has a push/pull ability for channel switching), pre-amp level knob and a master volume knob. It has three EQ knobs (treble, middle and bass..each with the push/pull ability for a boost), presence knob and a built in spring reverb. Its got a line in and out on the back, 2 speaker outs, ability to change the ohm load if you add more speakers and a jack on the back for the footswitch Sounds AMAZING! swing by and check it out!
