Guitar Tone Imprinting Processor

SIM1 XT-1

Ever wished you could play your Tele but hear your Les Paul? This clever box of tricks makes that possible...

Though it only fully came to market in 2019, the XT‑1 was voted 'Best Accessory' back in 2018 at the Winter NAMM show. Having put it through its paces since I bought one as an early Christmas present to myself, I can see why...

Using SIM1's proprietary patented technology, the XT‑1 allows guitarists to create and store profiles of electric guitars which can then be used as sources to be modified by the stored profiles of other guitars. For example, the single-coil pickup of a source guitar can be made to sound like the humbucking pickup of a target guitar, or vice versa.

Overview

Designed and hand-built in Italy, it's encased in an all-steel enclosure with an off-white surface and finished with a barcode of black and red stripes. The rear panel carries the unit's quarter–inch jack audio I/O sockets, which comprise a mono TS input, a balanced TRS output (for connection to acoustic guitar amplifiers, mixing consoles, audio interfaces etc) and a mono TS output jack for connections to effects pedals and electric guitar amps. On either side of this group of jacks sit the on/off switch and a non-locking, centre -negative connector for the supplied linear "super-noiseless" 9V, 1A power supply. On the right-hand side of the XT‑1 sits a USB 2 port that allows the connection of either of the two supplied accessories — a USB Wi-Fi adaptor, which can connect the pedal to a smartphone/tablet, or the SIM1–branded USB stick, used for backup and transfer of data to a desktop computer. Although this port can be connected to a MIDI‑USB adaptor to allow MIDI program change messages to be sent to the XT‑1 from an external controller or computer, it cannot be connected directly to a computer USB port — indeed, damage may result.

The top panel features a two-line (16 characters per line) monochrome LED display, which shows the XT‑1's operational status, and a red LED that illuminates when the unit is in its True Bypass mode. A row of three non-latching footswitches not only handles bypass and the selection and recall of the 99 possible on–board target guitar profiles, but also controls the source guitar profiling process, menu navigation and editing of the XT‑1's presets and on–board effects.
