That's nonsense, Radial are used worldwide by major venues & artists. I have an Avalon U5 V1, the Radial J48 sounds better, deeper & more detail. KT is made in China, its Behringer in a different box, the break after a while. I have 20 DI's, nearly all Radial, they haven't broken yet.
This is true. Radial is a Canadian company with world-class products. I own the Power 1 rack mount power cleaner and am currently looking at getting the BigShot ABY amp switch to run both my Tonex pedal and Kemper Profiler pedal simultaneously into my EV PA system.
You need 1 Mega Ohm input impedance for electric guitar, that's the same impedance as tube amps, the Twin has 1Meg input & high dynamic range, adding a DI will just add more noise & alter the sound by softening transients, that's why some DI's cost more, they don't mess with the sound. Any guitar with single coil pickups will have noise, tube amps are noisy & amplify the noise of the guitar, if an amp is emulated properly that have noise, a DI isn't going to fix that.
I don't think we should hold it against them just because they are Canadian, they probably couldn't help it..
