Great Eastern FX Design-A-Drive

The Great Eastern FX Design-A-Drive is a low- to medium-gain overdrive pedal from UK builder Great Eastern FX, designed by David Greeves¹²³. Its central idea is that no single overdrive voice suits every guitar and amp combination, so instead of a fixed tone stack it gives you a set of controls that reshape the pedal's frequency response on the fly. As RockBoard's PedalPedia puts it, it is "an overdrive you can redesign on the fly to deliver exactly what you, your guitar and your amp require"⁴.

The pedal is built around a proprietary tone circuit that aims to remove the hit-and-miss tonal compatibility between an overdrive pedal and an amp⁵. Delicious Audio relayed the builder's intent: "We wanted to create a pedal that let you be the designer, changing the frequency response on the fly to suit whatever guitar and amp they are using"¹. On That Pedal Show, Mick and Dan called it "a super flexible overdrive" when they demoed it as one of four new-to-them pedals⁶.

The controls: gain, edge, level and the six-way width switch

The Design-A-Drive has three knobs and one switch: Gain, Edge, Level, and a six-position Width selector². What sets it apart from a conventional overdrive is how the Edge and Width controls work together to re-voice the pedal rather than simply trimming highs or lows.

The Edge knob is the more unusual of the two tone controls. Premier Guitar explains that it "controls the top end of the frequency spectrum, simultaneously adjusting two separate filters, a gentle treble roll-off and a more intense cut in the high presence region, as well as subtly affecting the aggressiveness of the circuit's hard-clipping diodes"⁷. MusicRadar describes the same dual-filter behavior, noting that the high-presence filtering in turn interacts with how the pedal clips your signal⁵.

The Width switch deals in midrange. Each of its six positions moves from a thin response to progressively fatter ones⁵, and Guitar.com's reviewer found it "gradually adding body to the tone in a way that feels much more musical than cranking a conventional bass knob"².

Because the Gain and Level controls are wide ranging, the pedal covers a broad spread of uses. MusicRadar notes the pre-gain and output levels "function in a fairly traditional fashion, offering everything from transparent boosting to harmonic overdrive"⁵, and Premier Guitar adds that with the gain turned down it can serve as a powerful tone shaper and clean boost⁷. The circuit itself is a hard-clipper, with the clipping routed to ground³.

Guitar Pedal X's reviewer logged his preferred settings as "Gain @ noon, Edge at c. 2 o'c, Level @ 3 o'c, Width @ 2nd notch!"³

How it compares and who uses it

Great Eastern FX is also known for the Small Speaker Overdrive, and Guitar Pedal X compared the two siblings directly. Both are hard-clippers with the clipping routed to ground³, but the reviewer heard the Design-A-Drive as "rawer, grittier and fuzzy-edged", closest to the sound of early 80's garage rock, and judged it "more of a live arena style weapon of choice - with plenty of texture, edge and bite, to cut through the band mix"³.

The pedal has a documented user in Peter Stroud, Sheryl Crow's guitarist, who uses it in a rig covering country, heartland rock, folk, blues and poppier material³.

What reviewers said

Reviews across the press agreed on the pedal's flexibility. Guitar.com's Richard Purvis reviewed it as an overdrive pedal made in the UK, true bypass, powered by a 9-volt mains supply only, priced £229². Delicious Audio introduced it as "a low- to medium-gain overdrive equipped with a couple of unique EQ controls, Edge and Width"¹, and That Pedal Show demoed it on camera as one of four new pedals in a November 2022 episode⁶.

Guitar Pedal X's Stefan Karlsson highlighted "its ability to rapidly and easily adjust its profile to suit a certain playback scenarios" as the pedal's core strength³. Writing in Guitar.com in 2024, Richard Purvis compared its character to the Bleak District Electric Terra: "But its character is quite different, more silky, less bitey, so you're definitely allowed to own both"⁸.

Availability and price

The Design-A-Drive launched in July 2022 at £229 in the UK and $265 in the US⁵, prices confirmed by Delicious Audio in August 2023¹. It was available direct from the Great Eastern FX website and through the company's dealer network¹.
