I thought I'd share this find since there is very little info out there about this Leslie amp.

I picked one up to work with my 1959 Hammond A-100 and a Leslie pedal. I'm currently using a homebuilt FRFR cab with an old RAMSA WP 1200 power amp for my Kemper, but decided I'd try it with the new Leslie. The Leslie has input channels for keys, instrument, and vocals, so I ran the Kemper into the instrument channel and was very impressed with the results. It's built like a tank. The Leslie is a 200 watt amp with a ported cab holding a 15" speaker and two 4" speakers. I doubt it's true FRFR, but it sounds excellent with the Kemper-better than my other cab. It's perfect for me as I play guitar, keys, and sing. Now I can use one rig for everything. It's definitely worth a look if you're in the market.
