MSA PEDAL STEEL: Jordan Bosstone Fuzz – Nashville Variant

MSA Pedal Steel Bosstone nashville vero layout v1 47bd2be85fa4

Just a little one from the Bosstone family.  This is said to have been used in MSA Pedal Steel guitars, and it’s basically a slight variation on the Nashville Bosstone circuit. These can be a bit noisy, so really have to watch your wiring and try for quite low gain on Q1.   It can … Read more

ASTRO AMP: Astrotone Fuzz, with Analog Man Mods

ASTROTONE Fuzz 015 guitar vero layout v1 1ecb3b033fd9

Perhaps best known as the Analog Man Astrotone Fuzz now, this started life as the Sam Ash Fuzzz Boxx and the same circuit also appears in the Astro Amps Astrotone Fuzz – which is a supremely cooler name, which is maybe why it has stuck. The original has 47n caps on this input and output, … Read more

ELECTRA: Distortion

ELECTRA Distortion 015 vero layout v1 b794d2e29c3f

I accidentally messed up a small Colorsound Fuzz Box board by drilling mounting holes in the wrong place – but I didn’t want to waste the vero board, and I thought an Electra Distortion & Colorsound Fuzz Box might make a nice pair of one-knob pedals.   Perhaps not the most exciting post to return … Read more

VOX: Tone Bender – vero & enclosure

4BC7D9A9 405E 4DEA 81C5 5421A0555E9C 5839a899d397

Some notes for later from a recent Vox Tone Bender build.  Mainly wanted to jot down the placement of the pots and switch, as this layout is quite tight in a 1590BB – there’s no room for error.   I probably should have made the layout a row or two shorter, but I just liked the … Read more

SOLA SOUND: Tone Bender MK1.5 – Original 0.15″ Vero Layout

SOLA SOUND MK1.5 Tone Bender guitar effect vero layout v1 27b167d42b85

A bit of a classic – the MK1.5 Tone Bender.  Some great phots and background information here on Fuzzboxes.org and some great video demos below – who better than Ant Macari to talk Tone Benders. Note that some earlier versions carried a 500k volume pot, instead of 100k resulting in more bass – ultimately bringing it … 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
