The LPD Pedals Seventy4 is a compact analog pedal that puts the sound of mid to late 1970s Marshall Plexi and Master Volume amps on a pedalboard. The maker classifies it as a distortion, overdrive and equalizer in one box, and the press describes it as an overdrive/distortion aimed squarely at the Plexi style of amp-in-a-box drive12. Delicious Audio calls it "an in-the-box recreation of the full distortion delivered by Marshall Plexi and Master Volume amps from the mid to late" '70s3.
The pedal is built by LPD Pedals, a company led by designer Lawrence Petross, who Premier Guitar says draws on over fifteen years of experience building amps and pedals4. The Seventy4 line takes the metal-faced Plexi and the first master volume JMP as its inspiration2.
What it does to your sound
LPD describes the Seventy4's voicing in terms of what a player hears: mids, harmonic overtones, presence and a low end that can be tuned to match any rig. The maker's own words1:
"Combine amazing mids, sweet harmonic overtones, presence for days and lush underbelly of lows that can be tuned to match any rig, the vintage '70s tones this little marvel can drive are legendary, and the gain available is beyond any throwback tribute."1
That last point matters for players comparing Plexi-style pedals: the Seventy4 is not limited to vintage gain levels. The maker positions it as going beyond a tribute piece, with more drive on tap than the amps it models would deliver1.
The Seventy4 and the Seventy4 Deluxe
The regular Seventy4 is the compact, single-channel version, priced at $210 as of August 20222. In August 2022 LPD also released the Seventy4 Deluxe, a two-channel version of the same circuit, priced at $299.992.
| Seventy4 | Seventy4 Deluxe | |
|---|---|---|
| Channels | Single | Two (Red and Green) |
| Form | Compact-sized pedal | Two-channel overdrive preamp pedal |
| EQ | Equalizer section | Global Bass, Mids, Treble and Presence shared by both channels |
| List price | $210 (August 2022) | $299.99 (August 2022) |
The Deluxe's global EQ provides Bass, Mids, Treble and Presence for both the Red and Green channels3. GuitarPlayer describes the two channels as sharing "a global three-band EQ and Presence"2. Delicious Audio's Matthew Wang notes the Deluxe is "an upgrade to the previous Barefoot version of this full-on Plexi pedal, featuring an extra Presence knob"5. The Green channel adds low-mid girth to the pedal's sonic profile, according to Premier Guitar4.
The Deluxe has no battery compartment, so it runs on external power4.
Where it came from
The Seventy4 sits in the LPD Pedals range alongside the Eighty7 Deluxe, a two-channel pedal from the same maker. RockBoard's PedalPedia describes the Seventy4's voicing as combining "amazing mids, sweet harmonic overtones, presence for days and lush underbelly of lows that can be tuned to match any rig," with gain that goes beyond a vintage '70s tribute1.
Delicious Audio has included the Seventy4 Deluxe in its roundup of the best Plexi-style pedals and Marshall-inspired distortions since 202135.

Questions
Is the LPD Pedals Seventy4 analog?
Yes. The maker lists the Seventy4's circuit type as analog, and the two-channel Seventy4 Deluxe is described in the press as an all-analog overdrive preamp pedal. There is no digital processing in either version.
What is the difference between the Seventy4 and the Seventy4 Deluxe?
The regular Seventy4 is a compact single-channel pedal priced at $210 as of August 2022. The Seventy4 Deluxe, released in August 2022 at $299.99, is a two-channel version with Red and Green channels sharing a global EQ section including a Presence knob, an upgrade over the earlier Barefoot version.
What kind of amp sound is the Seventy4 aimed at?
It is aimed at Marshall Plexi and Master Volume amps from the mid to late 1970s, specifically the metal-faced Plexi and the first master volume JMP. Delicious Audio calls it an in-the-box recreation of the full distortion those amps deliver.
Can the Seventy4 run on mains power?
Yes. The maker's product page lists mains operation as supported for the Seventy4. The Seventy4 Deluxe has no battery compartment, so it runs on external power rather than a battery.
Is the Seventy4 a distortion or an overdrive?
It sits across both categories. The maker classifies it as a distortion, overdrive and equalizer, while the press describes it as an overdrive/distortion and the Deluxe version as an overdrive preamp pedal. It is best thought of as an amp-in-a-box drive with a full EQ.
