Best Signal Processors from Top Stores

Updated October 11, 2026

Compare the best signal processors from top stores in one place.

Signal processors range from about $35.99 to $899.99. The lineup includes reverb units, compressors, phasers, and multi-effect pedals, typically housed in metal chassis with footswitches and knobs.

Look for processors that match the type of effect you need-reverb for space, compression for dynamics, or multi-texture units for creative shaping. True-bypass designs preserve your original tone when the unit is off.

Pay attention to control layout, digital versus analog circuitry, and whether the unit offers presets or programmable parameters. A sturdy metal case and reliable footswitches improve durability for stage use.

Questions

What is the difference between analog and digital processors?

Analog units use circuitry that can add warmth, while digital units offer more precise control and preset storage.

Do I need a power supply for all pedals?

Most pedal-style processors require a 9V DC supply, though some run on batteries.

Can I chain multiple processors together?

Yes, you can connect them in series to combine effects, but be mindful of signal loss.

What does true bypass mean?

True bypass routes the signal around the circuit when the pedal is off, preserving the original tone.
