Late 60's/ Early 70's Leslie Model 18 rotary speaker cab. These were specially made for guitarists to allow them to get that Leslie sound easily, using a single full-range speaker. The Leslie 18 is identical to the famous Fender Vibratone cabinet that has been used by many well-known guitarists over the years, such as George Harrison, Hendrix, SRV live and in the studio... etc. This one is in working condition although cosmetically it has suffered a few knocks from a life on the road - including the loss of the serial number plate - and it could probably do with a bit of TLC!
The speaker has been changed at some point in it's history from the original 4 Ohm 12" JBL unit to a (much better, allegedly) 8 Ohm 12" RCF L12P11 (from '83-'84). I've used this with various amp heads, and it sounds great. The rotary effect is generated by a single rotating drum - which is not the same as a classic L122 - but the effect is still a rich and phasey chorus/ vibrato. You probably know the sound.
It does not include the footswitch for bypassing or changing speeds unfortunately, although they can be found online, and there are also schematics available if you feel up to building one! Another thing worth noting is that at some stage there has been a jack socket let into the back panel which is connected to the speaker so it can be used without the footswitch as it bypasses the 9-pin plug. It's quite heavy (around 70lb +) and measures approx 28.5" x 21.75" x 15", so this is for collection only (or fully-insured courier at the buyer's expense) I'm afraid. Much of the Leslie 18's unique tone comes from the fact that the cabinet uses a guitar speaker, instead of a horn and woofer. The effect is dispersed horizontally, with grilles on the sides and top of the cabinet. With no built-in preamp, the Leslie 16 has to be powered by a separate guitar amplifier; in recording situations, microphones were placed next to the grilles in order for the effect to be heard, and depending upon positioning, this small speaker cabinet can create some of the biggest stereo Leslie simulations.
