The LPD Pedals Seventy4 Deluxe is an all-analog, two-channel overdrive preamp pedal aimed at players who want 1970s-era British amp tones in a pedalboard-friendly box1. It is the two-channel version of the company's flagship Plexi overdrive, the compact Seventy4, and LPD describes it as an in-the-box recreation of the full distortion delivered by Marshall Plexi and Master Volume amps from the mid to late '70s2. GuitarPlayer reported it as available now, priced at $299.99, when LPD unveiled it on 30 August 20223.
The Red channel features LPD's original Seventy4 circuit, the same circuit as the regular compact-sized Seventy4, while the new Green channel, in GuitarPlayer's words, "adds low-mid girth"3. Delicious Audio's write-up describes the Red channel as very similar to the original non-deluxe circuit, with the Green one created to complement it and voiced with a darker overall tone2.
The controls: shared EQ, per-channel gain and level
The control layout splits into two halves. Each channel has its own Gain and Level knobs, two knobs per channel in the bottom row, while a global EQ section sits on top and is shared by both channels2. GuitarPlayer describes this as both channels sharing a global three-band EQ and Presence3.
| Control | Scope | What it does |
|---|---|---|
| Gain | Per channel | Sets the drive level of the Red or Green channel3 |
| Level | Per channel | Sets the output volume of that channel3 |
| Low / Bass | Global | Shared low-band EQ for both channels2 |
| Mids | Global | Shared mid-band EQ for both channels2 |
| Highs / Treble | Global | Shared high-band EQ for both channels2 |
| Presence | Global | Shared presence control for both channels2 |
| Voice switch | Per channel | Two individual tone foundations per channel1 |
Because the EQ is global, switching channels changes the gain structure and voicing but keeps your EQ settings in place. On the Red channel, the Voice toggle switch delivers more of a mid-boost2.
Two footswitches handle the rest: Soft Touch Switches for turning the effect on and off and for selecting the channel1. Delicious Audio describes the same arrangement as one footswitch for engaging and bypassing the pedal, the other for switching between the Red and Green channels2.
The two channels cannot be stacked. They are alternatives you switch between with the Channel footswitch, not two gain stages you can run into each other2.
From the Seventy4 to the Deluxe
The Seventy4 Deluxe is a deluxe two-channel version of LPD's Seventy4 overdrive/distortion, which GuitarPlayer describes as "a more versatile pedal" than the compact original3. The compact Seventy4 is priced at $210, against the Deluxe's $299.993.
The line's inspiration is specific: GuitarPlayer notes that the Seventy4 takes "the metal-faced Plexi and the first master volume JMP as its inspiration"3. The designer behind it is LPD's Lawrence Petross, drawing upon over fifteen years of experience building amps and pedals1.
Delicious Audio's 2024 roundup of Plexi-style pedals treats the current Deluxe as an upgrade over the earlier Barefoot version of the pedal, featuring an extra Presence knob5:

The Seventy4 sits in a wider LPD range of Marshall-inspired and amp-in-a-box pedals. LPD's maker listing groups it alongside the One20Three, SIXTY8X, EIGHTY7 v1 and DUTCH 244, and the company had already released a two-channel version of its Eighty7, the Eighty7 Deluxe, before turning the same two-channel treatment on the Seventy4. Players comparing Plexi-style distortion pedals or overdrive pedals will find the Seventy4 Deluxe on the preamp-style end of that spectrum, with per-channel gain and a shared amp-style EQ.

Questions
What is the difference between the Seventy4 and the Seventy4 Deluxe?
The regular Seventy4 is a compact, single-channel pedal priced at $210. The Seventy4 Deluxe is a two-channel version: its Red channel uses the same circuit as the compact Seventy4, while a second Green channel adds low-mid girth and a darker overall tone. The Deluxe also adds a shared four-knob EQ with Presence and per-channel Voice switches, and is priced at $299.99.
Can you stack the Red and Green channels on the Seventy4 Deluxe?
No. The two channels cannot be stacked. You select between the Red and Green channels with the Channel footswitch, and a second footswitch engages or bypasses the pedal. Both channels share the same global EQ section, so switching channels changes the gain structure and voicing, not the EQ settings.
Is the LPD Seventy4 Deluxe analog?
Yes. The Seventy4 Deluxe is an all-analog, two-channel overdrive preamp pedal. LPD's maker listing for the Seventy4 circuit also lists it as analog, and the circuit is a recreation of the distortion character of Marshall Plexi and Master Volume amps from the mid to late 1970s.
What amps is the Seventy4 Deluxe based on?
The Seventy4 line takes the metal-faced Marshall Plexi and the first master volume JMP as its inspiration. Delicious Audio describes the pedal as an in-the-box recreation of the full distortion delivered by Marshall Plexi and Master Volume amps from the mid to late 1970s.
What does the Voice switch do?
Each channel has a Voice switch that brings two individual tone foundations per channel, for increased versatility. On the Red channel, the Voice toggle delivers more of a mid-boost. The switches let you flip between two voicings on each channel without redoing your EQ.
How much does the Seventy4 Deluxe cost?
The Seventy4 Deluxe is priced at $299.99, and Premier Guitar reported the same street price in 2025. The regular compact Seventy4 is priced at $210. The Deluxe is available at lpdpedals.com.
