T-RackS Leslie from IK Multimedia contains the best sounding Leslie of the entire digital world, with five legendary Leslie amps and six cabinets in one powerful module, that you can now use inside T-RackS 5 mixing and mastering workstation to further shape the sound of your tracks. The amps were recreated thanks to IK’s innovative Dynamic Interaction Modeling Technology, which can analyze and model the behavior of every electronic component in the circuit, as well as their mutual interactions, thus reproducing the exact behavior of the entire system in a non-linear and dynamic way.

Leslie 122
The classic of classics. Suitable for pop, rock, jazz and blues, when you think of the "Leslie sound," you are most likely thinking of a 122. A vintage unit from the early ’70s has been modeled and has a slightly warmer sound when compared to the 122A.

Leslie 122A
The Leslie 122A is the modern take on the most famous Leslie model, with a balanced input to the amplifier and a medium-tall cabinet that provides superb bass response. This has a slightly more open and upfront tone when compared to the classic 122.

Leslie 147
The Leslie 147 is another classic Leslie model with a different connector, slightly different power amp, an unbalanced input to the amplifier and slightly shorter cabinet. The overall sound is very similar to the classic 122 but with some noticeably and musically relevant differences. The one we modeled is a vintage unit from the mid-60s, with no reflectors on the horns, which gives another flavor to the sound and an even more tangible sonic difference from the classic 122.

Leslie 3300w
The Leslie 3300w is one of the most powerful models ever, featuring a 300-Watt RMS solid-state amplifier with a real vacuum tube preamp. Its sound signature is especially suitable for pop, rock, jazz and blues.

Leslie G37 / Studio 12
Guitarists of all kinds praise the G37 for its unmistakable tonal character. The onboard solid-state guitar amplifier with its tube preamp section can go from pristine-clean to down-and-dirty, for a variety of tonal nuances that only Leslie speakers can provide through a compact dual-rotor cabinet with a vintage voiced V30 12” speaker suited to guitar. The Studio 12, designed as a more portable amp for keyboard players, also uses a tube-driven solid state amplifier into a dual rotor design but has a 12” Eminence bass speaker tailored to the wider low frequency range of organs.
