I think they are a sample of 10538 Overture by Elo, so using a chamber orchestra might be the way to go...

For a bit of fun, guess which Fender bass has this high-quality sealed construction jack socket? For a bonus point, where was it made?

I've fixed lower power speakers with the sort of tissue used for model aircraft before, light but strong and conforms well to a curved or textured surface. You could use multiple layers. Several layers fo thin paper will be better than one of thick card as you want some flexibility. Not a fan of copydex, I'd use PVA diluted 50% with water, as little as you can get away with. If you can seal the hole, you're good to go for a temporary solution and no bodge on the cone will prevent you from having it properly reconed or replaced in the future. If it happened when setting up, I would use gaffa tape, one piece on either side of the cone 🙂

I did think of adding a third loop, just for the compressor, before the A loop. Apparently some people use an HPF between effects and amp to remove 'sub octaves' generated by effects (I can see how chorus/flange type effects could easily generate these).

Next idea forming in my brain... Switching box with two loops and three switches: A/B(which loop active if not on both or bypass) Both (in series) Bypass(neither) Rather than the usual A/B/Y arrangement. And build a high pass filter into the same box. Planned use: Bass ---> compressor ----> HPF -----> LOOP A ---> LOOP B -----> Amp

I thought you peeled it off the dual carriageway after particularly hot day...

I was impressed by 'Semi-Colon', their cover of Ring of Fire. Then there was their collaboration with Chuck D. and FLava Flav - Public Enema

Laser printed decal for a 'professional' finish 🙂 Gargh! It's tip negative!

No? They performed quite a lot of Phil Lynotts death. Yes, but no new albums. All the new recordings are as Black Star Riders.

Wow is that the last Arion 'Stereo' pedal left standing? I used to have the stereo compressor - still have the box, full of fishing lures with rusty hooks...

I've just completed a tiny High Pass Filter, very simple schematic and board here:

Ok, I've finally got round to etching the PCB, populating its and then testing the high pass filter. The 50mm square enclosure was challenging - even fitting the two jack sockets was tricky, spacers on the outside. The tall caps and voltage doubler IC (for +/- 9v) fit at bottom right. All caps are either 10u or 100n for simplicity! The PCB had to be carefully hacksawed(!) right to the edges of the tracks, I used soft faced vice jaws as a guide for the saw. Note one corner was too tight so I had to 'divert' the track: Power LED just hard wired to the power connector and switched -ve via the ring of the input jack, so not on PCB. Need to put on a proper decoration - and the right way up! First stick in a bottom B from my home-made frequency generator: 4V P-P, (actually no visible difference between in and out signals up to 6KHz - I didn't bother going higher): As hoped, gain rapidly drops off below 31Hz. This is 0.4V at 22Hz: 4.0 top 0.4 is gain of 0.1 that's exactly 20dB cut at 22Hz, which is pretty much excatly what the modelling software predicted. Kudos to Analog Devices! The nay-sayers will say I should have made the cutoff higher, but it's (supposedly) 'infrasonic' signals below about 16Hz that are the main problem.

Probably more profit than labour, with an automated cable stripper it's less than a minute to hand assemble those cables if you have the knack and no doubt at Chinese labour rates.

I'd make my own using physical switches 🙂 But I'm just joshing with you, I suspect if I said I was thinking of a new microwave you'd recommend the BOSS CUK-1 🙂

Greedy....

THing is tehy are using base-level Neutrik and Van Damme components, which are probably little different from ordinary non-crap components. The NP2x jack plugs are £2.04 each plus VAT if you order 50 from RS. NP2Rx is £2.52. Van Damme 'pro grade' XKE cable is 1.28 per metre in 100m reels. So to make 3m cables in bulk leave about £1.60 to cover other costs. But Designa will probably buy direct from Neutrik and Van Damme in much larger quantities so I think we can assume the £1.60 easily covers the assembly cost, leaving a similar profit on the parts to whatever markup RS are putting on.

'Other brands of switching poedal are available' 🤣🤯🙂🤣

Someone just posted a link that made me think 'which albums have given me the greatest pleasure?' Not the one that are the best, or my favourites, or that impress, or are the most technical. More like a 'Desert Island Discs' list but albums. This is my list of ten albums, in a rough chronological order of when I came across them. A New World Record, ELO - I started collecting ELO singles and I love(d) everything before Discovery (which was a huge disappointment). NWR probably just edges Out of the Blue, but I listened to these over and over again reconstructing each track listening to just the bass, the keyboards etc. I can recognise Jeff Lynne's production at 100 paces... Wish You Were Here, Pink Floyd - was I the only angst-ridden teenager who found solace in this album's melancholy? Live Rust, Neil Young - this and Rust Never Sleeps introduced me to a new type of music, raw, passionate with a huge range of emotion and delivery. On Stage, Rainbow - already a Rainbow fan, this just captured such a huge sound and almost makes up for the fact that I never saw Rainbow live. Woodstock - I have this on two cassette tapes, recorded off a reel to reel version of the album in a cottage in the Welsh countryside where we used to go just to be. Liege and Lief, Fairport Convention - this is the album that opened my ears to British folk rock and made me realise you don't have to put your finger in your ear and sing through your nose. Ironically Ashley Hutchins' bass driving it along, as Dave Pegg is probably my greatest 'bass hero'. Watt, 10 Years After - this was one of the albums, with SHHH, that I played along to over and again during the years when I was in bands. 10, Pearl Jam - I heard this, and Nevermind, and decided that perhaps music hadn't died after all. 13, Black Sabbath - I am a massive fan of Black Sabbath's music, especially the earlier stuff where there was more light and shade. Then 13 a came along and the whole album is like a puzzle box full of every little Ozzy-era signature while still feeling fresh and new, managaing (just) to steer clear of being a pastiche of earlier albums. It starts with the words 'Is This the End of the Beginning, or the Beginning of the End', and ends with a reflection of the very start of 'Black Sabbath' which I still find emotional. The Machine Stops, Hawkwind - I 'found' this after hearing Synchronised Blue on Phil Alexander's programme. For me it just rekindled my passion for Hawkind's music and was on almost endless repeat for weeks.

Not enough like buttons, near the top of my top ten albums of all time.

They are very 'sticky out'. I like a 90-degree really. But I have some pretty leads for use at home, like a cheap but lovely looking fabric covered Stagg one to go with my pseudo vintage and much modded Ibanez '335'
