Bass Compressor Pedal Buying Guide

TBefore you go splashing money all over the place and get the most expensive one, there are a few factors that you must keep in mind. Here they are.

True Bypass vs Buffered Output

These two terms essentially mean how the pedal will behave in a bypass mode. The true bypass will disengage when turned off, and the signal does not pass through the pedal. Whereas, in a buffered pedal, the signal is always routed through the pedal’s circuitry.

There is no right answer as to which is optimum, it depends on your choice. The buffered pedal can boost your signal and prevents loss, while the true bypass pedal keeps the signal pure and clean.

Compression Types

There are four basic categories in which bass pedals can be classified when it comes to compression.

  • Valve

These are also called Tube compressors and are one of the earliest compressors out there. Many prominent artists, including the Beatles, used them. These are now very hard to get and can be pricey, but they deliver an authentic and vintage sound.

  • VCA

Voltage Controlled Amplifier or VCA converts AC bass signal to DC voltage. Which regulates the volume of the VCA. These are the most affordable and ubiquitous bass pedals due to their versatility. VCA pedals can be used for several genres of music.

  • FET

FET stands for Field Effect Transistor, and it is an upgrade over the tube technology. Here, the signal goes through a transistor for control gain.

  • Optical

Optical is arguably the best compression type according to some experts. It uses a light source to modify the signal volume which produces subtle and smooth sounds,


  • Attack/Release

These two parameters define the time taken for the compression to kick in or withdraw from the signal.

  • Level

Level or makeup gain can also be interpreted as volume. In other words, compressors with the higher level parameter will produce louder sounds and vice versa. Most compressors come with a specific level which is often not explicitly mentioned.

  • Ratio

Ratio means the proportion of the signal gets compressed when it passes through the pedal. You’ll find numbers such as 3:1 or 10:1 compression, which denotes the ratio of the compressed signal and the uncompressed signal.

Boss is one of the most prominent names in the music electronics industry. They are a subsidiary of the Japanese multinational firm Roland Corporation which is an industry leader. Besides compressor pedals, Boss offers a wide range of products including amplifiers and loop-stations.
