@Lotte Cutts the alpha is 40 watts, two channels with individual gain , one a mic/ line, and eq / reverb on master, loud enough and relatively light. The compact 60 also has two similar channels but separate eq’s and four effects including reverb, delay and chorus that can be panned across one or both channels, a little heavier tha the 40 but definitely a punchier sound. Both are great, I’ve had an Alpha for over 10years with no problems and recently bought the 60 off eBay at a bargain price, I was the only bidder!
