The One Control Agamidae Tail Loop is One Control's entry level programmable switching system for guitar effects. It sits on a pedalboard and switches up to six effect loops in and out of the signal path, either one at a time by hand or from stored presets, and it doubles as a small power supply with six 9V DC outputs for the pedals on the board.1
Loops, presets and modes
The Agamidae Tail Loop carries six loops, and One Control states that all loops are true-bypass, meaning a pedal in a switched-out loop is removed entirely from the signal chain.1
For programming, the unit holds 100 presets, organized as 20 banks with 5 programs per bank. Two operating modes cover the two ways players use a switcher, and a Master Bypass function is also included:1
| Mode or function | What it does |
|---|---|
| Recall Mode | Calls up the stored presets1 |
| Direct/Edit Mode | Engages each of the six effect loops individually for manual control of the pedalboard1 |
| Master Bypass | Bypasses the unit's switching altogether1 |
In practice, that means a player can run the board by hand in Direct/Edit Mode while building sounds, then switch to Recall Mode to call up whole pedal combinations as stored presets for songs.1
Power
The unit runs from an industry standard 9V DC center-negative adapter. One Control recommends the One Control EPA-2000 model for low noise and reliability.1
Beyond powering itself, the Agamidae Tail Loop provides six 9V DC outputs to power your effects pedals, so a modest board can draw its power from the switcher rather than from a separate supply.1
One Control's US product page listed the Agamidae Tail Loop as sold out as of 26 October 2026, at a regular price of $274.99 USD.1
Where it sits in One Control's range
One Control describes the Agamidae Tail Loop as its entry level programmable switching system, the most accessible point in the company's switching line. Players needing more loops or features can look at the larger One Control Crocodile Tail Loop OC10, while the One Control LWP Series 5Loop Switcher with Tuner Out Kit covers simpler loop switching with a tuner output.

Questions
Is the One Control Agamidae Tail Loop true bypass?
Yes. One Control states that all loops on the Agamidae Tail Loop are true-bypass, so a loop that is switched out takes the pedal connected to it completely out of the signal path. The unit also offers a Master Bypass function alongside its Direct/Edit and Recall modes.
How many presets does the Agamidae Tail Loop have?
The Agamidae Tail Loop holds 100 presets, arranged as 20 banks of 5 programs per bank. Alongside the presets, a Direct/Edit Mode lets you engage each of the six effect loops individually for manual control of your pedalboard.
Can the Agamidae Tail Loop power my pedals?
Yes. As well as switching, the unit provides six 9V DC outputs to power your effects pedals, so it can act as both a switcher and a small power distribution point on the board.
What power supply does the Agamidae Tail Loop use?
One Control says to power the ATL with an industry standard 9V DC center-negative adapter, and recommends the One Control EPA-2000 model for low noise and reliability.
Is the One Control Agamidae Tail Loop still available?
The product page on One Control's US site listed the Agamidae Tail Loop as sold out as of October 2026, with a regular price of $274.99 USD.
