I use a Stanley trimmer to score each side quite firmly and snap the pieces apart. I don't often have chipping. I have a belt sander in my workshop so go out there, put the sander on its side and smooth the edges on that. Takes less than a minute. I wear a mask of course! Then i use the trimmer...

Clear coat like Trussart?

Speaking as someone who has some genuine emu experience I can say that it's extremely difficult to drill one. As soon as you get close enough they either run away, steal your icecream (happened to my dad) or peck you.

Well it's definitely a Russian Ge transistor. But 8701 isn't the type - maybe a date mark?

Reminds me of when I completely rewired a 1982 Suzuki GS1100. I kept worrying about ground loops and having to remind myself this was a bike, not anything audio. Although once it was back up running it did sound pretty good.

FWIW I have a pedal which uses a 1µF output capacitor and I used a tantalum cap there. When building I accidentally put the cap in backwards. The pedal still worked but I could hear DC on the volume pot and it was noisy - a kind of crackling noise similar to a worn out tube in an amp. Once I...

Mainly what I'm saying is that (a) I can be wrong, and (b) Chuck knows everything! I definitely don't. What I really enjoy with this hobby is that it doesn't cost much (yet!) to try these things. If it sounds good it's handy to know why, but I can still enjoy the fact that it sounds good. Then...

That's it! Man, you know me too well!

I have a piece of 140x30mm jarrah about 40cm long I've used for years. I drilled some holes in it to hold pot shafts for desoldering the lugs. They also hold 90 degree jack plugs in place while I solder patch cables. I have some spaced at around 100 and 150mm so I can hold both jack plugs at the...

I use a callused finger. My index finger has quite a good callus from something... I think it has to do with our hobby but I can't quite put my finger on it... Something with strings?

1 sold! So who was it??

My "knowledge" is purely anecdotal. Chuck often kindly points out where I am wrong! Most of my observations are just that - observations. I have built Big Muffs with 2N5088, BC549C, BC550C and 2N3904 transistors (and probably others). I like the sound that the 2N3904s produce because it seems a...

That's one of the few Friedman amps I've played. A friend who I built an amp for lent me his mini Dirty Shirley - the EL84 version with a 10" speaker. Quite impressive it was too.

Well that is one scary story with a happy ending! I love building amps and my favourite amps to build are Marshalls. (The Aussie Jason isn't Jason Stone is it??) My main amp right now is a modded Marshall 1987 circuit built as a 1x12 combo in a tweed style cab. It makes the amp sound like the...

My friend is a guitar tech who got a new job in a place where he looks after music gear of all kinds. They used to have an electronics guy there but no longer. There was loads of ICs and stuff so he brought them around in case I could use them. I think most of them are for more complex gear than...

A while back a friend found a heap of obscure ICs and knowing that I dabble in amps and pedals he brought them around to see if I could use them. Amongst them was a tube of 4069UBDC 14 pin ICs. I drew up a layout for a version of the Red Llama to try with this chip then promptly forgot about it...

Hey @Robert - I notice a lot of Mr Black PCBs being offered - is this because (a) you think they are really good, (b) they have been requested, or (c) you just wanna piss him off? I'm cool either way!

I am looking at the schematic for the White Washer Distortion and C3 and C4 are two 1µF caps in parallel to VRF. Surely I could just use a single 2µ2? Is Mr Black using up his bulk shipment of 1µ caps?

You weren't temped to put an image of satan somewhere on the board? I really, really loathe shimmer reverb...

In principle I don't have any issue with AI. But in practice I do... My wife is a writer and she recently learned that a few of her fiction books have been used by AI developers to train AI to write. She was never asked if this was ok or paid for this. It's obviously theft of intellectual...
