I just bought the Strymon Iridium pedal to assist me on live gigs, as we have for a while been working without a backline and using the DI option.
I was at first using a Kemper Stage, but because of a 'hum' problem that wouldn't go away, switched to my Zoom G5n, which provided my amp and echo tones admirably.
I was pleasantly surprised that the Zoom matched what I was hearing from the expensive Kemper, but was assured by friends in the band and others in the business that it was delivering what was needed, the required sound. For me, that's good enough.
On the Zoom G5n, there are options to set up patches with up to nine separate pedals, including amplifier and speaker models, but they take up memory and you can run out of space for some patches you may wish to set up. So - I figured out that with a separate amp and cabinet pedal, it would free up some space on the Zoom, allowing more complex echo taps and complex reverb, should the need arise.
I have just come back from trying it out at our local residency, where we set up on a Wednesday for Thursday's gig, where we have a run through and are able to experiment with gear and new stuff we wish to try. I set up my Zoom G5n as normal, but removing all the amp simulation from each patch, leaving the Zoom to handle effects only, ie Echo, Reverb, Fuzz, Tremolo, Chorus, Compression and whatever else I may need in a patch. i put the Strymon Iridium after the ZoomG5n and took a line to the PA, setting the Strymon in the clean Vox AC 30 position and using a single 12'' Celestion blue speaker emulation. I can confidently say that it works perfectly and sounds terrific, having played several Shads instrumentals with the lads listening, helping me 'tweak' the echo patches, comparing with the Shadows recordings as we went along making fine adjustments. What I have learned is really useful, having the lads in the band to 'bounce' off and we all discovered that there are fine margins to get those tones right for each track.
It's fiddly and time consuming, but what the hell, we enjoy it and when you get a result it gives you quite a buzz. I recommend the Strymon Iridium to anyone looking to find a lightweight option for using live through a PA system or home recording or practice.
