The Matthews FX Architect V3 Foundational Overdrive is an overdrive pedal from Matthews FX, the Richland, Washington builder formerly known as Matthews Effects. It was shown at NAMM in January 2019, where owner Rick Matthews demoed it at the Delicious Audio Stompbox Booth1. What sets the V3 apart is its EQ section: an active 3-band EQ giving control over the Treble, Mids and Lows, so a player can boost or cut those frequencies to match the guitar and amp combination1.
The active 3-band EQ
The EQ in the Architect V3 gives you active control over the treble, mids and lows. Rather than the passive tone controls found on many overdrives, which can only cut frequencies, the Architect's EQ lets you actively boost or cut each band to shape the guitar's tone to match the guitar and amp combination1.
Guitar Pedal X's Stefan Karlsson lists the EQ among the pedal's headline features, alongside "different clipping on both the Overdrive and Boost elements"3. For a player, the practical difference is flexibility: a guitar and amp pairing that is too dark can be brightened, and a mid-heavy amp can be scooped or pushed further, all from the pedal rather than the amp.
Controls and clipping options
The pedal is laid out as two footswitchable sections, drive and boost2.
| Section | Controls |
|---|---|
| Drive | Clipping (Germanium / Lift / Silicon), Output, Gain, Low, Mid, High, Drive footswitch2 |
| Boost | Boost Type (Silicon / MOSFET), Boost Level, Boost footswitch2 |
The three clipping options on the drive side give, in Delicious Audio's words, "3 different colors of gain which helps you dial in the Architect to work" with your setup1. Each has its own character:
- Germanium: compressed and tight1
- Silicon: very tight and crunchy1
- Diode Lift: only the slight natural clipping, which Delicious Audio calls great for pushing a dirty amp1
The Lift setting is the one to reach for when you want the pedal to add volume and a touch of grit into an amp that is already breaking up, while the Germanium and Silicon settings impose more of their own clipped character on the signal1.
What V3 added to the Architect
The Architect line goes back to at least November 2016, when Matthews Effects unveiled the Architect V2 Foundational Overdrive, described by Premier Guitar as "a mythically inspired overdrive with improvements"4. The V2 carried a Gain control for the amount of overdrive mixed in4.
V3 keeps the active 3-band EQ and the clipping options inherited from the previous version, and adds an independent boost circuit to the company's classic circuit1. That boost has two diode flavor options, Silicon or Mosfet, chosen with the Boost Type control, plus its own level knob and footswitch12. Because the boost is a separate circuit with its own clipping, the pedal can go from clean-ish push to stacked drive without touching the drive settings.
What reviewers said
Guitar Pedal X's Stefan Karlsson, reviewing the pedal in 2019, called it "a very formidable and feature-rich pedal" with one reservation3:
"a very formidable and feature-rich pedal - let down somewhat by the huge output drop when you switch to Germanium mode3."

The same 3-band EQ and dual clipping design kept the Architect V3 in Guitar Pedal X's compact overdrive roundups into 20205.

Questions
What clipping options does the Matthews FX Architect V3 have?
The overdrive side offers three clipping settings: Germanium, Diode Lift, and Silicon. Delicious Audio describes Germanium as compressed and tight, Silicon as very tight and crunchy, and Diode Lift as leaving only the slight natural clipping, which the site calls great for pushing a dirty amp.
What is the difference between Silicon and Mosfet in the V3 boost?
The independent boost circuit added in V3 has two diode flavor options, Silicon or Mosfet, selected by a Boost Type control alongside a Boost Level knob and its own footswitch. The boost therefore has its own clipping character, separate from the Germanium, Lift, and Silicon options on the drive side.
Does the Architect V3 have an EQ?
Yes. The Architect V3 has an active 3-band EQ with Low, Mid, and High controls. Delicious Audio describes it as giving active control over the treble, mids and lows, so you can boost or cut these frequencies to shape the guitar's tone to match your guitar and amp combination.
What is different between the Architect V2 and V3?
V3 keeps the active 3-band EQ and the clipping options inherited from the previous version, and adds an independent boost circuit with two diode flavor options, Silicon or Mosfet. The boost has its own level control and footswitch, so it can be engaged separately from the overdrive.
Which clipping option is best for pushing a dirty amp?
Delicious Audio points to Diode Lift for that job, describing it as leaving only the slight natural clipping, which the site says is great for pushing a dirty amp. The other two settings, Germanium and Silicon, add more of their own clipped character.
