The most important thing to know about this compressor is that it colors your tone, and some musicians feel that it does so pretty drastically. To our ears it seems to add in a twangy mid-range hump, which is likely why it’s been such a fixture in the country guitar scene for the last few decades.

While it may not be transparent, the Dyna Comp is still the compressor of choice for tons of professional musicians. It’s also been used by musicians outside of the country-sphere, with David Gilmour being one of its most notable users.

The only real concern for some guitarists about this pedal is that it has a hardwire bypass configuration. A portion of your input signal (the signal that comes from your guitar) is routed through the pedal, which can cause treble and volume loss.

This is a good value inexpensive compressor which we've recommend in our guide: The Best Compressor Pedals.
