The Leyland Head Full is a lo-fi echo pedal, a delay design built around the PT2399 chip. Delicious Audio's Paolo De Gregorio describes it as "a creative lo-fi echo based on what's probably the most inspiring chip for delays, the PT2399." According to the same write-up, the pedal can produce "ethereal atmospheres, haunting soundscapes, and full-on walls of noise," as well as more subtle analog-style delays with tape-style artifacts, slapbacks, or clean repeats. It is built in England: "Built by caring English hands," as the write-up puts it1.
Controls and footswitches
The Head Full keeps its controls focused on shaping the character of the repeats rather than offering a long list of parameters1.
| Control | What it does |
|---|---|
| Distortion knob | Adds saturation to the repeats, as much as you want1 |
| Inf(inity) footswitch | Sends the circuit into self-oscillation1 |
The Distortion knob is the pedal's main voicing tool: it lets you push the echoes from clean repeats into saturated, degraded territory, which is where the lo-fi character comes from. The Inf(inity) footswitch is separate from the main bypass switch and is meant to be held or tapped to send the delay circuit into runaway self-oscillation, a feature players use for walls of noise and ambient swells1.
Power
The Head Full is a lo-fi echo built around the PT2399 delay chip, with a 1 x 1/4" high impedance input and a 1 x 1/4" low impedance output1. Delicious Audio describes it as capable of ethereal atmospheres, haunting soundscapes, and full-on walls of noise, as well as more subtle analog-style delays with tape-style artifacts, slapbacks or clean repeats1.
With a current draw listed as greater than 100mA, the Head Full may exceed what some daisy-chain setups or low-current supply outlets can deliver. Give it its own outlet on a supply rated above 100mA.

Questions
Is the Leyland Head Full true bypass?
Yes. Delicious Audio lists the Head Full as a True Bypass pedal, so when it is switched off your guitar's signal passes through untouched, with no buffering of the dry tone.
What power supply does the Leyland Head Full need?
The Head Full runs on 9 to 12V through a 2.1mm center-negative power jack. Delicious Audio also notes that 18V operation is available, with the caveat that the modulation knob sweep changes at that voltage. Current draw is listed as greater than 100mA, so use a supply that can handle it.
What chip is the Leyland Head Full based on?
The Head Full is built around the PT2399 chip. Delicious Audio calls it probably the most inspiring chip for delays, and it is the same chip found in many lo-fi and analog-style echo designs.
Where is the Leyland Head Full made?
The Head Full is made in England. Delicious Audio describes it as built by caring English hands.
Can the Leyland Head Full self-oscillate?
Yes. A dedicated Inf(inity) footswitch sends the circuit into self-oscillation, letting the repeats build on themselves until you stop it.
