The LPD Pedals Sixty8 Deluxe is a dual-channel version of the company's Sixty8 Overdrive, a Plexi-style drive pedal. Where the original Sixty8 gives you one voice, the Deluxe splits it into two footswitchable channels, a low-gain Green channel and a high-gain Red channel, and adds an independent boost section with up to 24dB of full range volume. Pedal of the Day described it as "essentially providing two pedals in one enclosure"1.
The circuit traces back to a real amp: the Sixty8 is designed to sound like the LPD Pedals company owner's own 1968 Marshall Plexi 12000 series amp2. LPD Pedals is an Arizona-based builder, and the Sixty8 line sits among its Marshall-flavored releases. Delicious Audio describes the Deluxe as delivering "that dynamic Plexi tone, with the vintage Marshall amps' signature sustain at relatively low distortion settings, plus an extra switchable higher gain channel"3.
How it differs from the original Sixty8
The Sixty8 Deluxe takes the original Sixty8 Drive and, in Delicious Audio's words, "makes it a performance monster"3. The differences a player will notice:
- Two channels instead of one. The Green channel is the lower gain voice and the Red channel the higher gain one, with a center LED showing which is active: green for low gain, red for high gain3.
- A split tone control. The original's single Tone control is replaced by separate Treble and Bass parameters, which Pedal of the Day said "allow[s] you to dial in your perfect sound with ease"1.
- An added boost. A 24dB full range boost that functions independently, allowing use with the Sixty8 channels or on its own3.
- Separate channel controls. The two channels have separate Volume, Tone and Gain controls4.
The controls and footswitches
Each drive channel carries its own Volume, Tone and Gain controls4. The Treble and Bass controls do specific jobs borrowed from the original Sixty8 design:
| Control | What it does |
|---|---|
| Bass | Pre-clipping, designed to offset the shelving filter on the Gain control; simulates jumping or bridging the channels on the real amp, letting you mix in as much of the "Normal" channel as desired2 |
| Treble | Increasing it makes the pedal snappy, responsive and somewhat jangly, which Delicious Audio calls great for rhythm and rhythm/lead hybrid styles2 |
| Drive | At higher settings activates a gradual high-pass filter that cuts some low end for a tighter tone, just as on the original3 |
| Boost | Up to 24dB of extra full range volume, fed into the overdrive3 |
The pedal has three footswitches. The center footswitch alternates between the two drive channels, and there is independent switching for Active/Bypass, Gain Mode, and Boost3. The switching itself is soft touch and click-free, which Pedal of the Day called "silent and no-shoes friendly"1.
With the two channels and the boost, the player has five tone options at their toetips3:
- Clean (bypass)
- Green
- Green + Boost
- Red
- Red + Boost
The boost
The boost section gives up to +24dB of full range power and can function in tandem with the drive channels or alone1. Its character changes with the knob: it stays clean until about the 1 o'clock position, then starts breaking up and adding its own overdrive/fuzz sound1. That means the boost can serve as a simple volume lift for solos, or pushed further as a third dirt voice.
Power and connections
The Sixty8 Deluxe runs on 9V or 18V1. Pedal of the Day's take: "You can run the Sixty8 Deluxe Overdrive on 9v, but it sounds incredible at 18v as well"1. Delicious Audio's Plexi pedal guide describes it as a dual-channel Plexi distortion that runs internally at 18V for extra headroom4. Current draw is low at 12mA3.
Connections are top mounted Switchcraft input, output and DC jacks3, which Pedal of the Day praised as high quality parts that "will keep you rocking for years to come"1.
If you want the extra headroom the pedal is built around, you will need a power supply capable of 18V. At 12mA it is easy on a pedalboard power supply either way314.
What reviewers said
Published coverage of the Sixty8 family has been positive. Pedal of the Day's 2021 review highlighted the range of sounds, saying the channel and boost combinations give "access to a slew of great Plexi tones on the fly"1. The same review singled out the 18V sound and the click-free switching1.
Delicious Audio added the Sixty8 to its list of Best Plexi-Style Pedals in 20252, and its Deluxe page sums up the design goal inherited from the original: the pedal had to be super low noise, with completely natural note sustain and decay, free of any strange fizzy artifacts2.
"The Sixty8 delivers that dynamic Plexi tone, with the signature sustain at relatively low distortion settings."

Questions
How is the Sixty8 Deluxe different from the original Sixty8?
The Deluxe takes the original Sixty8 Drive and splits it into two footswitchable channels: a low-gain Green channel and a high-gain Red channel, each with its own controls. It also adds an independent boost section with up to 24dB of full range volume, and the single Tone control is replaced by separate Treble and Bass knobs.
Can the boost on the Sixty8 Deluxe be used on its own?
Yes. The boost functions independently, so it can be used with the Sixty8 channels or entirely on its own. It stays clean up to about the 1 o'clock position, then starts breaking up into its own overdrive/fuzz sound, which makes it usable as a second dirt voice rather than just a volume lift.
Should I run the Sixty8 Deluxe at 9V or 18V?
It runs on either. Pedal of the Day noted that it works on 9V but sounds incredible at 18V, and Delicious Audio describes it as a dual-channel Plexi distortion that runs internally at 18V for extra headroom. If your power supply offers 18V, that is where the pedal is at its best.
What amp is the LPD Sixty8 based on?
The Sixty8 circuit is designed to sound like the LPD Pedals company owner's own 1968 Marshall Plexi 12000 series amp. The name and the target are the same across the Sixty8 family, including the Deluxe.
What are the five sounds on the Sixty8 Deluxe?
Clean (bypass), Green, Green plus Boost, Red, and Red plus Boost. The Green channel is the lower gain voice, the Red channel the higher gain one, and the two drive channels cannot be stacked, so the combinations come from pairing either channel with the independent boost.
