Seeker Electric Effects MKI Tone Bender Fuzz (Lineage Series)
Seeker Electric Effects returns to the channel with a second Lineage Series fuzz — this time it's the MKI. Welcome back to Edge of Breakup.
In this episode the Seeker Electric Effects Lineage Series MKI Fuzz takes center stage — featuring the Wide Sky Guitars P125C Cutaway with Curtis Novak P90s and Emerson Custom Treble Bleeds, into the Benson Amps Monarch 2x12" via the Boss Waza Tube Amp Expander.

The Tone Bender MKI is the original British fuzz — the 1965 Sola Sound circuit that predates the Fuzz Face derivations and uses three germanium transistors rather than two, producing the distinctive nasty spitting buzz, cutting midrange, ripping attack, and blooming sizzling sustain that made it the fuzz of choice for the early British Invasion tone. Jimmy Page's earliest Yardbirds recordings. Jeff Beck. Tony Iommi before the Marshall. The MKI circuit is the ancestor of everything.
Mike at Seeker describes the Lineage Series MKI as "a culmination of many years of learning and refining this circuit." This build comes in the "Sola" tuning — straight-ahead MKI style, using the component values most commonly found in vintage units to recreate the classic 1960s character without modification. NOS NKT OC77 and Texas Instruments 2G301 germanium transistors — period-correct choices that land the attack and decay exactly where a vintage MKI should. NOS capacitors. Carbon film resistors. Built on a custom eyelet/PCB hybrid board following the original point-to-point layout closely.
Two external controls: Level and Attack. That's it — the same minimal control set as the vintage originals. The Level pushed past unity is explored from 09:05 onward, using the output to push the Monarch's input stage rather than adding gain in the fuzz circuit itself. The Attack sweep is explored across the full range from 06:16, and the interaction between Attack level and guitar volume knob is a significant part of this demo — P90s and an MKI have a specific reactive relationship that makes the cleanup sweep unusually expressive.
Lineage Series custom folded metal enclosures. True bypass. LED indicator. Center negative 9V or battery.
