I like it when all the parts in a circuit actually do something. If it doesn't absolutely have to be there, get rid of it. I see a lot of circuits these days use an absurd number of ICs and not use sections as you see above in the Marshall 59 OD. I love nothing more than Chuck telling us we...

Wow - thanks! Interesting.

No you haven't made a mistake - there is flub galore in this circuit. It is based on something which isn't designed to be a guitar pedal. It's supposed to sound like crap. Only for me it's not the kinda crap I wanted - I was hoping for a different crappiness of crap. And I wholeheartedly agree...

It never fails to impress me how many parts can be used to build a pedal to fuck up a perfectly good guitar sound. Nice work Mr Grobbins!

Paul, I really appreciate you taking the time to post. I'm sure we all do. (well, except for the weirdos) A lot of my player friends are huge fans of the Tim and Timmy. You have quite the fan club in Western Australia.

FWIW I measured the drains of the transistors in this circuit on two versions I made. On both Q1 was under 4V - around the 3.6-3.7 mark. Q2 & Q3 in both were between 4 and 4.6V. So I tried getting the voltages all up to around 4.5VDC to see if it made any difference. Tonally very little...

Built another one yesterday and rejigged the layout to make it smaller. It works.

Nice build! I built one of these years ago and remember liking the sound. Actually I was thinking about you this morning when I was having my morning coffee at a nearby lake. It's walking distance from where I live and I frequently walk to a cafe near the lake for a coffee and croissant. I...

It's just too expensive where I am to buy NOS any more. As I build my own amps I like to use JJs and tune the amp to the tube. It's fun and affordable (except the bit where I can't afford to buy amp parts from the US any more and even tubes are becoming crazy expensive). The bits which are...

With the cost of the tariffs you're probably better off buying a used drill press! With a VERY simple jig (fence) it's easy to drill very accurately.

I like the JJs. I have used them in Marshall 18W clones and AC15 clones with excellent results.

That looks amazing! I've only ever built on tag or turret board, never PCB for an amp. I'm a tinkerer though so turrets really suit me. If I was to build something where I was certain of parts values something what you have done here would be killer. As for drilling tube socket holes, you...

That makes sense. I really wondered where it was used!

I think there comes a time when we all could use some BAT41s. I should have said - lovely job as always Michael. I wouldn't mind trying this one - I love the LPD68.

This surgical tubing we all use in Fender style guitars - is it really surgical? Where do surgeons use it? Is it what they use in a triple bypass surgery?
