The leads channel has controls for "shape", Mid shift, & level. THe rhythm channel has controls for low, high, and level Reverb has two controls, lead and rhythm. THere is a 1/4" jack labeled Insert, whose function is unknown at this time. The chorus has controls for depth and rate. On the back panel there are jacks for a footswitch, stereo effects loop, stereo headphones/line out and one for external speakers, (40W RMS per channel, 2 OHM min. Load. It is solid state. And for my curreny level of play it is satisfactory.
I use the amp with a chinese made Les Paul clone electric and a Ovation clone acoustic/electric. I am learning rock, blues and folk. I also use it to amplify a Blues Hard. It seems to work well with all of the above, although I'm still learning.
