A good IR sounds like the real thing audibly, but doesn’t have the physical presence of a real cabinet driven at power by a real amp. Both are correct, but I fall into the group of fascinated myself. For some of us, the process is fascinating and for others, those folks just want to get the sound of the cabinet that they like and move on. That’s why you could find four IRs, all made from the same type of cabinet, but that still sound different. Impulse Responses are actually recorded from a real world cabinet and their duration allows the IR file to capture how the cabinet responds under different frequencies and loading. Old style cabinet simulations tried to use tone maps to fake out a cabinet and to be blunt, they were pretty lousy. That’s why the same amplifier head sounds so different into a 2x12 open back cabinet compared to a 4x12 closed back cabinet. We hear constantly about the tone of different amps and a lot of the time this gets tied back to the preamp of the amp, and while the preamp stage of an amplifier definitely contributes, in a classic tube amp, the majority of the uniqueness of tone comes from the output transformer (a long and wonderful conversation for real gear heads) and the speaker cabinet. The device supports Impulse Response files of either 200ms or 500ms duration, where the longer IRs tend to be more accurate. There are also 128 slots where you can store your own IR files. The device also includes an Impulse Response library for cabinet simulations that includes 144 IRs from Boss and 10 IRs direct from Celestion. There is a DSM&Humboldt Bass Simplifier with a much richer range of options, but it is a dedicated box and purchase separate from the guitar version. While I do appreciate that there are bass amp emulations in the unit, they are a bit skint in terms of choice. It offers amplifier emulation for both guitar and bass amps (a unique value proposition over the others which are guitar amp only) The graphics below show the options that come in the box.

The IR-200 is built on the same solid chassis as the other 200 series stomps from Boss. It takes the form of a stomp box like the Strymon, whereas the DSM&Humboldt is more a desktop device. It is the last option that interested me. The IR-200 is a device that you can use in front of an amp if you wish, or to an FRFR cabinet or into your recording interface. I recently have had the opportunity to evaluate the new IR-200 from Boss. I own the DSM&Humboldt Simplifier which is an all analog approach, that it, I think, quite excellent and also the Strymon Iridium which is as one would expect from the geniuses at Strymon, a DSP based solution. With Iridium, there are no menus to wade through-just familiar, responsive amp-style controls for instant, easy adjustment.Between miking a real amplifier and using a powerful digital modelling tool like a Neural Quad Cortex, exist these middle solutions that offer the ability to emulated an amp or three, and some number of speaker cabinets. Instant adjustments to your tone are right there on your pedalboard, only a footswitch away.

Want to play live with the exact same tones that you use at home or in the studio? Or have access to multiple amp and cab setups without having to lug them on stage? Leave your amps at home, and connect Iridium directly to the house PA system.Going direct eliminates the need to mic an amp, giving sound engineers the option to send your amp and cab tone directly to a wedge or in-ear monitors. With Iridium, it’s a snap to dial in a direct tone that will truly inspire and sound great whether you are monitoring through in-ears, floor wedges, reference monitors, or studio headphones. Place Iridium on your pedalboard and send gorgeous stereo amplifier tones, stunningly realistic cabs, and lush room ambience direct to a recording interface or PA system. Skip the hassle of lugging around or miking amps. Iridium gives you three iconic amplifiers, with a total of nine impulse response speaker cabinets that complement the tonality of the amp.

Discover inspiring tube amp responsiveness, unprecedented impulse response speaker cabinet realism, and controllable natural sounding room ambience. Now there is a pedal that truly delivers that sound and feel, with simple controls for effortlessly dialing in the perfect amp tone when going direct.

Nothing reveals the true nature of your guitar and your playing like a world-class tube amp driving a perfectly matched speaker cabinet in a great sounding room.
