I had V1 of this pedal - microchip is dead and I went for a few opinions and few electronics engineers they all have the same answer - there is no help.
Then I bought this one, V2 of FlyRig, new generation.
Right after first year of use there was issue with power cable - I replaced it.
After another year of usage there was major problem with noise on compressor. Again I went for electrician and a few of them said same thing - some chip that is in charge for that par of pedal(compressor) is dead and there is no replacement. Now I cannot use that at all.
To summarize: this sounds good, sansamp sounds good, but quality of hardware and overall endurance is TERRIBLE.
If you want SansAmp just get that single pedal, do not buy these piece od crap.
By the way, I have friends guitarist who have flyrigs for acoucist, Richie Kotzen model, etc, they all had some issue sometime.
For this amout of money I expect much more.
