Love this thing...!

This is an incredible sounding piece of equipment! The rotary Leslie effect is perfect and even the smaller cabinet has an incredibly rich sound. I don't have a full sized Leslie to compare it to, but to my ears its sound is incredible. I was glad to discover the grill cloth doesn't just cover big rectangular openings, but covers louver-like slits just like the older Leslies. This along with the diffusion cones on the treble horn creates the sound that Don Leslie intended. In the old days we ripped off the cones and removed the back panels using the back of the thing as the front to eke out the last decibel from the 40 watt amp, but we lost some of the subtlety of the sound. I'm sure some Studio 12 users will do the same thing (especially since the controls are on the back - but the manual warns us that removing the panels will void the warranty and cause possible injury - I suppose by leaning in too close and having your nose clipped by a spinning horn), but I'd guess the 100 watt amp can keep up with a lot of guitar amps. I've always loved the sound of the Leslie (who doesn't) and back in the '60's I made sure to add a Fender Vibratone to my setup. I was finally able to get a 147, but looking for more power and portability I got Yamaha RA 70, later I went through a few Motion Sound amps, and ended up with a Ventilator. While the Ventilator is great for playing in a loud band, in a quiet setting it never sounded right. I realized I was playing less organ in those settings because of that and knew I needed a real Leslie. The Studio 12 looks great - I guess they were painted black, but mine has charcoal grey plastic like coating that looks kind of like the old Fender Tolex and it actually seems to sparkle under the lights. They say it's heavy, but it weighs the same as my old keyboard amp and 2 guys can easily carry it (the handles snap in place when not in use so they don't rattle when you play). They say it's expensive, but it costs about the same as Fender Super Reverb - expensive, but not outrageous for a quality piece of gear. If you love the sound of the Leslie and you don't have the room or money for a 3300 a new 147 and you don't want the headaches of an old 145, you gotta check out the Studio 12!

THE STUDIO 12 EXCEEDED MY EXPECTATIONS!!!!

GREAT SOUND, EVEN THOUGH THE WOOFER IS ONLY 12 INCHES, IT IS EXCELLENT AND HANDLES ALL MY HAMMOND XK3C CAN DISH OUT. THE CONSTRUCTION AND DESIGN ARE EXCELLENT AND I CAN LIFT AND MOVE IT MYSELF (I'M 6FT AND STRONGER THAN AVERAGE), THOUGH MOST PEOPLE WOULD NET A HANDTRUCK OR ANOTHER PERSON. I HAD A NEO VENTILLATOR, BUT THIS LESLIE BLOWS IT AWAY ON RECORDINGS AND ESPECIALLY IN PERSON. FINALLY, A REAL LESLIE THAT NEITHER BREAKS MY BACK OR BANK ACCOUNT!!!

Fanstatic with both Hammond and acoustic guitar

Moved and joined a church that by happenstance had a red-cap Hammond A105 that hadn't been turned on in 35 years. Needless to say... The A105 needed a Leslie, and the Studio 12's price was equivalent to purchasing a used Leslie. Added traditional Main-Ensemble-Echo and Chorale-Tremolo switches, the latter requiring a SPDT configuration to interface to the Studio 12's TRS-type control jack. The TRS connections were easily reverse engineered from the included foot pedal by using an ohmmeter. I had always been Echo-only (Leslie-only) when playing on an A-series, however it was apparent that the Studio 12 lacked accustomed bass. However, when put in Ensemble and gain balanced with the A105's internal amplifiers/speakers, it was absolutely perfect -- better sounding than my B3-122. Great pedals to distinct 1-foot drawbar increments. DC to daylight on a Hammond. So much so, if I had to do it all over again, I would seek an A100 and Studio 12. The acoustic guitarist plugged into the Studio 12's low-level input, and what an acoustic pleasure it was. The guitarist had never played through a Leslie, and was smitten. There are YouTube G37 demos, and they are just as valid with the Studio 12. No perception of bass lacking and spectrally flat stand-alone, but no 16-foot drawbars to contend with in this mode. Perhaps it's the 12's G37 heritage. 4.0 for Hammond mode due to bass, poor documentation, and refused assistance after calling Hammond-Suzuki and speaking with their tech. Anything beyond sanctioned plug A into sanctioned jack B was not only completely lost to them but forbidden, and you'll be spoken to like a wayward child. I'm an electrical engineer and wanted to save time, but it would be nice to provide assistance for those customers that aren't. Sleeve to ring for slow, sleeve to tip for fast. Would that be too difficult? It was. An easy 5.0 for acoustic guitar -- plug, play and enjoy.

Leslie Studio 12 – was hoping for more.

The unit is heavy (85lb), and the dimensions make it impossible for one person to pick up with the handles. If you want to move it around you will need wheels. Exceptionally solid construction. Was easy to set up. The footswitch has a loud click, which is intrusive when playing softly. A Korg CX-3 / Leslie Studio 12 combination had a very loud background hiss when set at mid-range; by contrast, dual Roland KC-150s were completely quiet. The Studio 12 is powerful and appears to provide every bit of 100W. The rotary effect seems subtle, compared to a Leslie 122. Controls are on the back of the speaker, which made adjustments a bit cumbersome. After two hours of playing the EQ was never quite satisfactory. The impression is that there are multiple frequency peaks and wells in the output. Despite the ultimate return of the unit, it definitely could work for some players.
