Tone Bender MKI offboard wiring d2f09106d545

Just a reference for me – this is specifically for this layout mounted above the pots. MKI TONE BENDER OFF-BOARD WIRING PLAN The final soldering of the board to the pots has not been done yet – that will be done when it is mounted on the actual enclosure lid, as opposed to the dodgy piece … Read more

GHOST EFECTS: Sounds of Today

GHOST Sound of today tagboard layout v1 d6bf2ec6764e

The Sounds of Today is Ian Sherwood from Ghost Effects adaptation of the MKI Tone Bender.  It’s all explained by Ian here, with photos.  There are also plenty of photos of these in various stages of construction Instagram too, so you can see a few variations along the way. Short story: The attack has been replaced with a fixed resistor.  The resistor … Read more

ZONK MACHINE: Component Values Table

Zonk Machine generic schem 63818739536d

Not a huge amount of variation on Zonks in terms of component values, and at one stage this was all on the MKI table, but I decided to split the two.   ZONK MACHINE SCHEMATIC ZONK MACHINE COMPONENT VALUES Link to table BUILD NOTES In my experience, the Zonk can be a little easier to make … Read more

TONE BENDER MKI: Component Values Table

Tone Bender MKI generic schematic 74f21158c4d4

Like most people, I’ve never even seen an original MKI in the flesh, so I’m relying on online references for this.  The references below all relate to original MKIs – or pedals that are said to be direct replicas of originals built for Sola Sound. Please feel free to comment and point me in the right … Read more

GARY HURST: Tone Bender MKI – Castledine, 0.15″ Vero

GARY HURST CASTLEDINE MK vero layout 9ed15c8d61c1

I wasn’t aware of this version of the MKI until today.  I’m sure you have probably seen the new line of Tone Benders that Sola Sound is releasing.  I noticed that the Stu Castledine version was on vero, and the rest were all on the more familiar MKI board.  So after a little digging, it turns out this … Read more

JOHN HORNSBY SKEWES: Hybrid Zonk Machine (Modded)

Zonk Machine BE Hybrid 015 7c5156213ffe

Similar to the previous Zonk Machine, this has a MKI switch for a larger input cap.  Have had this on the breadboard recently, and decided to jump to a vintage-style veroboard.   There are of course more differences between a MKI Tone Bender and a Zonk than just an input cap, but for convenience’s sake, … Read more

JOHN HORNBY SKEWES: Zonk Machine, 0.15″ Vero Layout (modded and original)

JHS Zonk BE 015 vero layout v1a 095f75f9f5ec

This is my version of the Zonk Machine, based on one of the early vero layouts.  I added a switch for the input cap, which is possibly the most unoriginal mod known, and increased one of the input caps from 1n to 2n2. I used an OC76 for Q1 and Q3 and an OC44 for Q2.  I found … Read more

JOHN HORNBY SKEWES: Hybrid Zonk Machine, 0.15″ Vero Layout

HORNBY SKEWES Zonk Machine Hybrid vero layout f3c5866f28e6

This is the original layout for the Hornby Skewes Hybrid Zonk Machine (Silicon / Germanium).  Unfortunately, the trimmer needed to be a different size for the layout, so I had to make a strange triangular marker. HORNBY SKEWES HYBRID ZONK MACHINE – 0.15″ VERO LAYOUT (ORIGINAL)

These are now available from sunetec_au on ebay.  I previously purchased a couple of wedge enclosures from them, and they are really well-made.  It’s the right size, and it’s made from decent steel. Shipping was free and fast from Hong Kong.  It has rubber feet instead of pressed metal bumps – think I prefer rubber … Read more
