The Echo Fix EF-P5 FET Compressor Matched Stereo Pair is two EF-P5 FET Compressor pedals sold together with consecutive serial numbers, so the two units are matched for stereo compression work. Each one is a compact, 100% analog FET compressor pedal, a dynamics processor built around the field effect transistor gain-reduction design used in classic studio limiters. Echo Fix describes the single pedal as delivering "uncompromising analog tone and flexibility in a compact, pedal-friendly form."1
What the pair is for
The EF-P5 is sold here as a matched stereo pair, intended for two-channel duties such as a stereo instrument setup or a bus compression role in a recording rig. Echo Fix ships the pair worldwide one business day from the purchase date, so a set ordered direct arrives quickly almost anywhere.3
The controls
The EF-P5 covers the main compressor parameters a player or engineer would expect from a studio-style unit, in pedal form.2
| Control | What it does |
|---|---|
| Ratio selector | Switchable 4:1, 8:1, 12:1 and 20:1 settings2 |
| Attack | Variable attack time, with a broader range than traditional FET compressors2 |
| Release | Variable release time, sharing the same broader range2 |
| High Pass Filter | Frequency-selective compression and low-end clarity1 |
| Mix | Blends compressed and dry signal for parallel compression1 |
The wider attack and release range matters because traditional FET compressors are known for fast, fixed-feeling timing; Echo Fix says the EF-P5 loosens that up. The High Pass Filter keeps bass out of the detector circuit so the low end stays clear, and the Mix control lets you dial in parallel compression, the technique of blending a heavily compressed signal under the untouched one.12
XLR connections
Each EF-P5 has a Combo XLR input and an XLR output. A Combo jack accepts a standard XLR plug, so the pedal connects to XLR-equipped gear on both the input and output side, which suits studio patching and line-level sources as well as pedalboards.1
Buying in the United States
Echo Fix states that for USA customers it covers tariff and custom charges via its express courier, and that the checkout price is all inclusive. The pair ships worldwide one business day from the purchase date.1

Questions
What does matched stereo pair mean for the EF-P5?
Echo Fix sells the pair as two EF-P5 FET Compressor pedals built with consecutive serial numbers, so the two units are matched for stereo operation. One pedal can handle the left channel and one the right, giving you linked stereo compression with two identical units rather than two pedals that may differ unit to unit.
What compression ratios does the Echo Fix EF-P5 offer?
The EF-P5 has four switchable ratio settings: 4:1, 8:1, 12:1 and 20:1. Delicious Audio's Paolo De Gregorio described them as selectable ratios from 4:1 to 20:1 on the ratio selector, covering gentle leveling through to firm limiting-style control.
Does the EF-P5 have a parallel compression control?
Yes. The EF-P5 has a Mix control for parallel compression, which blends compressed and uncompressed signal. Delicious Audio also noted the mix/blend control as part of what makes the pedal precise for tracking, mixing and live use.
Does the EF-P5 use XLR or quarter-inch jacks?
The EF-P5 uses a Combo XLR input and an XLR output, according to Echo Fix's product page. A Combo jack accepts an XLR plug, so the pedal is set up for XLR connectivity on both sides of the circuit.
Does the EF-P5 have a high pass filter?
Yes. Echo Fix includes a High-Pass Filter for frequency-selective compression and to maintain low-end clarity, so bass-heavy content can be kept out of the detector and the low end can stay even under compression.
Are tariffs included in the US price of the EF-P5 pair?
Yes. Echo Fix states that for USA customers it covers the tariff and custom charges via its express courier, and that the checkout price is all inclusive. The pair also ships worldwide one business day from the purchase date.
