I stopped at my guitar shop today and was immediately teased with a custom cabinet containing a Leslie rotating speaker assembly. The cabinet work was really sharp and the sound was equally impressive. It took a lot of restraint to walk out of the shop with my wallet still in my pocket. It is still tempting me. I only had a 30 second demo though and wonder if the effect that it delivers is really worth the money. Would it be more of a gimmick that gets boring or would it be more versatile than it appears? It is a low watt speaker with dual speeds so it has limited versatility right there, but I have a couple of low watt amps that would likely sound great through this speaker cab. I do have a birthday in another week, but really don't want to spend that kind of money on something that ends up being a conversation piece except for some rare usage for that doppler effect. Thoughts? Give me some ownership perspective here.
