Cool, just realised i put the gain pots in the schematic backwards so they'll all work in the reverse... Oh well, this is my first PCB in about 5 years....
-
Okay yeah £2.68 for 5 PCBs delivered feels like it shouldn't be profitable. I used to be a buyer for a contract manufacturer and that's not far off the wholesale/volume prices we used to pay with negotiated discounts... Anybody fancy a heliotropic PCB when they arrive? I can post the schematic when I'm home, but it's basically a modified Muff (no clipping on the 2nd gain stage) that goes straight into a preamp/boost with a Muff tonestack. Edit - apologies, £3.60 for Lead Free HASL. Still cheaper than some coffee's i've bought recently...
-
What PCB prototyping services have people used recently? I traced the fuzzrocious heliotropic years ago and i couldn't remember how it sounded so I breadboarded it this weekend and it's great. Bit unwieldy for stripboard but I've knocked a PCB together in kiCad. $37 for 3 from oshpark. Will I get cheaper than that? I know years ago oshpark was pretty much the only game in town but I know a few other prototyping services have popped up. I know Digikey do it but as an employee of Farnell I can't give money to the enemy...

I wouldn't want to put you out, the schematic and PCB layout should be enough, don't have altium but should be able to get them into KiCad - if you don't mind sending me the files I'll happily take a PCB, been a while since I've done a fully SMT board, should be an interesting challenge.
-
That's fine, should still be doable by hand - I'm very tempted to give one a try, how did you assemble it without a silkscreen, have you got a BOM with a key to the footprints?
-
It's hard to tell scale, are the smd resistors/caps mostly 0805?

Clearing out some branded pedals I'm not really using now I'm not using a proper board anymore. Priced to move. UPDATE - Bumping old topic rather than relisting - available as of 17/04/25 Currently got some of the other patches on there but will wipe it back to factory settings before posting. With a free online editor you can load patches from the other MS-70 pedals which makes it super versatile. Boss DD-20 Giga Delay - £130 posted Honestly no idea what this is worth, had it for a looooong time and don't really want to let it go, but I'm just not using it these days. In pretty good condition for its age. Have the original box. Boss LS-2 Line Selector - £55 posted I think this is an old silver label version that's apparently somewhat valuable, but it's not in the best condition and it's an LS-2, I'm not gonna add on a premium for a shiny label. -
I don't know how the rest of you feel, but i think anyone who doesn't have a small semiconductor fab in their shed and a resistor winding station in their bathroom is just a poser.

People do it lots of different ways, my general method - Drill first Sand with 400 grit Coat of primer, dry Coat of paint, dry 2nd coat, dry Apply label graphics Coat of clear coat, dry 2nd coat of clear coat, dry Sometimes 3rd coat of clear coat The clear coat I use is good but it takes a.while to dry properly, in summer I stick them outside under a pyrex bowl to get the benefit of UV - I've toyed with getting a UV lamp.
-
Not the best pictures but it's Taiwanese, September 1989. Thought it was 88 so I retract the older than me comment, it's got a month on me. Still in better condition than me though... -
Currently saving up for boring grown up things like a house so I've enacted a strict policy of self funding brand name pedals so these have to go to fund new flights of fancy. Digitech Bass Whammy - In great condition, very minor cosmetic imperfections but that's it. With box. I've uncharacteristically misplaced the PSU as I've ran it off my power bank. Can include a PSU that will work if required. Got my eye on something so priced to move at £130 posted Boss OC-2 - Good condition, some cosmetic chips and scuffs but it is older than I am... Also priced to move at £120 posted Not considering trades at the moment, would do a deal on both if someone was so inclined.
-
Yeah I'll have one if you sell them, it's been on my stripboard build list for ages
-
Not to mention the.completely garden variety TMB tonestack that could have extremely easily had a mids control. But hey, expecting 4 knobs for $1200 just isn't reasonable...
-
Nobel clone from c2c mostly built just waiting for a step bit so I can drill the 22mm hole for the XLR and mount the DI daughterboard. The regular output is better than I thought it would be but still way too transparent to be worth what the original costs... Others who've built it have said the magic is in the DI (it does use a £70 transformer after all) so I'm prepared to be convinced.

Musikding sell a few kits - https://www.musikding.de/navi.php?qs=relay+bypass unfortunately they've stopped selling PCBs on their own for most of their kits. Fuzzdog do an optocoupler bypass PCB too which isn't as nice as a relay bypass but should be silent enough and the footswitch mounts on it so it's very space efficient.
-
Does anyone want any PCBs from deadendFX? - https://www.deadendfx.com/products There's a few that I want but their shipping rate has sky rocketed since i last ordered - $60 for a fair few PCBs - anybody interested in splitting shipping costs?

Bent bridge on old Tanglewood Rebel
bobbass4k replied to max_overdrive's topic in Repairs and Technical
I might have the original bridge from my old rebel 4k somewhere if you just want a cheap option and aren't bothered about upgrading - yours for postage, assuming I can find it. When I changed mine I put a hipshot on and just re-drilled.- 14 replies

Yeah I found it hard to get good results with stamping. I eventually worked out a good process of - -big sturdy block of wood inside enclosure - couple of self tapping screws with big washers through the pot and footswitch holes to stop it sliding - clamp block of wood in workmate/ vice I also found it useful to use a punch to tap a dent in, just to give the stamp something to bite. I may have just had cheap stamps but sliding was my main issue. As bloke said, the force required is pretty immense.
-
Not had any issues, even on fairly sizeable orders. They're another one that I think might just be winging it and hoping to get away with it, but no charges on deliveries yet.
-
Nope, never does, he always marks them as $12 value. Honestly, I don't know how these places get away with it, pedalpcb does the same, but hey, it's their risk.
-
I bought a few so didn't end up being too bad, got the 2 separate L5 boards as well - came quick as well, 4 days i tihnk?
-
I've got a xenotron and an L4 PCB, just waiting for all the parts to arrive. I'll let you all know how it goes...
-
They're good general purpose dual opamps, next time you need a tl072 or a 4558, pop an lf353 in. 4250 might be an interesting choice for a rat circuit.
-
Last chance before eBay is perfectly fair, to me at least. I've had a lot of pedals languish in the marketplace here for weeks or months. eBay is pretty much a guaranteed sale, and sometimes you just need something gone.
-
Most pedal designers use the same reference design for the 7660s, if you check the schematic for the pumpernickel i would imagine the charge pump section is identical. if you use the LT1054 make sure you isolate pin 1, either cut the trace on the pcb (bit dramatic) or carefully bend the leg so it doesn't go in the socket.
