Like all thing gear related, want usually wins over need. I need a small practice amp. My initial thought was Roland Cube micro. It would probably be just fine for what I need. Or the Yamaha THR10. You know, something small that doesn't get too loud (I share the house with a wife) but also has some different types of sounds. I'm just starting our again and a 30 year layoff and I wasn't very good then. I get a practice amp is all I need. But then I start thinking, which usually gets me in trouble. I've heard the Boss Katana line and like them. The Katana 50 sounds interesting for not much more than the Micro cube and less than the Yamaha. The Katana 100 isn't that much more than the Katana 50 and only a little more than the Yamaha. Then I found out the Katana 100 head has a 5 inch speaker and I could use it as a practice amp for now, and someday get a cabinet if I needed to play with others. I realize that probably isn't that likely but you never know. I also realize that any of the Katana amps would be set to .5 most of the time. It should be pointed out I'm 62 years old, so really the idea is just to have fun. Although I did go to Berkee when I was a kid for a couple of years as a drummer and do have a bit of theory happening. The cash isn't a problem. Am I nuts?
