Steve, the only bad thing people have said is about reliability, but thats not involving the pedals as far as I know, check out the amazing line up they have, some cool pedals for sure, they are super quiet and live up to the claims from what I've heard so far.
They are using a modeling technology to obtain all this wonderfulness for so cheap:
What exactly is RSM?
Effects processing devices have been around
for a very long time. They have taken the form
of everything from mechanical doohickies
that raise and lower the pitch of a string, like a
“whammy bar,” to the electronic circuitry that
recreates the highly complex reflected sound
of a subterranean cavern. Ever since early
mortals began making sounds, we’ve been
trying to make the sound better or alter it to our
liking. It’s part of our very nature.
At BEHRINGER, we build some of the finest
audio gear around, so it was only natural for
us to use our expertise to build a better stomp
box. But to do so, we first had to develop
an entirely new technology—Real Sound
Modeling. Our RSM technology combines stateof-
the-art DSP technology with sophisticated
algorithms that emulate real-world acoustic
environments. Such high-level processing
requires electronic architecture that takes into
account virtually all factors affecting sound.
The sound of a musical instrument is
affected significantly by a number of factors
before it is actually heard: the materials used, the
instrument’s design and construction, and the
components incorporated into the transducer
and amplification system. Even the subtle
interaction between amplifier stages can affect
the overall quality of the sound generated by
real instruments through real amps. This is
especially true in tube amplifiers, where the gain
structure of preamp stages creates a cascading
effect all the way to the output
Put simply, the average stomp box processor
does not have the power to mimic these subtle
nuances, which are so critical to attaining the
level of realism that BEHRINGER RSM technology
achieves. Thorough research and analysis of
these factors has enabled us to reinvent the
stomp box! RSM equipped pedals deliver
the detail of true-to-life amplifier and effects
modeling, without unwanted artifacts or fakesounding
approximations.
The high-performance RSM engine is only
available in BEHRINGER products that bear the
RSM logo. Hearing is believing.
