Big fuzz pedal = even bigger riffs. A very special one off germanium fuzz, built around a pair of 'spam can' NKT transistors and a slew of other vintage components (mostly harvested from some incredibly old Pye radios)

"Hen's Teeth TS" overdrive pedal doing some sweet higher gain tones. This thing is packed to the brim with magic unicorn hair and unobtainium mojo

The "Hot Toddy" is my flagship discrete op amp transparent overdrive pedal. This particular version is an extra special one made for the Leeds Pedal Show 2026 raffle

As part of the continued celebrations for the 10th anniversary of JSA Effects, I've built an extra special "Horse Whisperer" - my infamous discrete op amp Klon - in an Ernie Ball/John Mayer "Silver Slinky" tin. It's available right now on my Reverb store for less than you'd think 😉

I built a tube screamer pedal with the rarest of the rarest parts, including a vintage TL4558P, MA150 diodes, and blue 'orange drop' capacitors (that's right; orange drops, but they're blue in colour! 😮) and a whole heap of other cool things. It sounds like this - "Hen's Teeth TS"

Is it green? Is it purple? Is it gruple!?! Who knows! All you need to know is that it sounds incredible and is part of a very special batch for early next year (also the makers on the knobs glow in the dark)
