Open Discussion / Small & 'Weird' Effects

« on: July 01, 2020, 09:07:18 AM »

Hi,
Fixing up my mates broken Bad Stone has given me the bug to start up this hobby again (will see how long that lasts).

I want to put a little something extra in the package when I send his Bad Stone back so, any suggestions for any small and weird effects I could build up and gift them?

Cheers

General Questions / Build Docs - MiniTaur V3.1

« on: July 01, 2020, 07:30:00 AM »

Hi,
It's been a while since I've build anything and I'm looking for build docs for old unfinished projects.

Does anybody have build docs for the MiniTaur V3.1, I'm pretty sure it's a PickDropper 1590A Klone.

Thanks

Open Discussion / Anodised metal knobs

« on: July 16, 2016, 05:01:58 AM »

Hi,
I've been looking for knobs similar to the chase bliss audio ones which look like they might be anodised metal ones from the pictures(?)

Any ideas where I may be able to get some? If they're push on ones for knurled knobs, even better.

I'm in the UK so have already looked at Farnell, RS, etc. but didn't have much luck for the shaft size and length we're all used to using, though I could have easily missed them.

Cheers,
Marcus

Open Discussion / NAD - also a problem :(

« on: May 22, 2016, 09:26:24 AM »

I picked up a blues junior (cream board) with tone stack and power stiffening mods done for £200.

There is a problem with it though and I think it might be a mechanical problem.  The video shows the problem hopefully.  I think physical vibrations are shaking something loose..... maybe.  I tried turning the bass and middle to 0 and it didn't seem to occur anymore.

I did also notice the power valves were very hot, though I'm not sure if they're unusually hot.

I did actually play it at a similar problem for a good hour or so with no problems.....

Any thoughts and maybe where I should start? 

Thanks!

Open Discussion / DC-DC Converter Pedal PSU whine

« on: May 19, 2016, 02:11:34 AM »

Hi,
I'm working on a tiny PSU to fit into a pedal board that I wanted to power with my USB battery pack (phone charger thing) and also for using all those 5v USB plug in phone chargers around.

I got a couple Murata MER1S0509SC 5v to 9v DC-DC converters (as that's what I could find locally) and I've tried it out on the breadboard using my phone charger.  The charger puts out a steady 5v's under load, the DC converter puts out around 12v with no load and around 9v under load depending on the amount of pedals, seems to drop .1v the more pedals that are daisy chained.

The problem is I'm getting a high pitched whine through the amp.  The switching frequency of the DC-DC converter is 62kHz, have I made a mistake here?  I thought that'd be fine as it's above 20kHz.  Also, the max ripple & noise is stated at 20mVp-p, have I seriously underestimated this? Would putting it in it's enclosure help? as said it's on breadboard with lots of long crocodile clips attached to jumpers and stuff (probs could have clipped straight onto the pins now I think about it).  Am I just going to have to accept I need to use some extra filtering? didn't really want to use any components other than the converters.

I've powered a few different pedals with it thinking it could be possible heterodyning with modulating effects but it's happening with simple IC & tranny based drives and fuzzes too.

Any help is appreciated.

Cheers,
Marcus

Open Discussion / FYI: 1590a Eddystone equivalent.

« on: May 17, 2016, 10:41:37 AM »

Hi,
Just realised there are some Eddystone equivalents to the Hammond 1590A, I thought they only had 1590B (27134PSLA) and 1590BB (29830PSLA). Like the others its basically the same size but with more angled edges, corners and less of a slope on the sides. More importantly to me, they're also cheaper



They were £3.14 each at Farnell up until 20 units. 1590a's are £4.33 each for comparison.

Cheers,

Open Discussion / Smallest/flattest DC plugs

« on: April 01, 2016, 08:09:56 AM »

Hi,
So I picked up an 'actual' pedalboard (rather than an old shelf) recently, a PT Nano+ so I got some of those pancake jacks too so I can squeeze as much on it as possible.

Now I've noticed however the dc plugs I have stick out just as much as the old right angle jacks I had!

So, what are the smallest DC plugs you all know of? I'm sure I found some whilst searching the net a while ago which were pancake-jack-esque but I can't for the life of me find them again.

Cheers for any help.

Open Discussion / Chorus Hunt

« on: December 31, 2014, 08:25:15 AM »

Hello,
What are your favourite chorus'?  I've had a Tonepad CE-2 with all the mods in the past but it's always on and off the workbench as it was an early build with poor construction and the traces are starting to lift (self-etch), so it's time to think of a new one, also there was just too much stuff with the mods - the more pedals I do, less is more.

Tonepad CE-2
Madbean PorkBarrel CE-2
Little Angel
Celeste Chorus

Anything else worth noting?

Cheers,
Marcus

Open Discussion / LED Indicator to 18v Phantom Power Box

« on: September 01, 2014, 12:52:17 PM »

Hi,
Not really sure if this was the right place to put this but here goes.

Is there any reason why I shouldn't add an LED to this following circuit?  It's going to be for some Shure MX202's in a portable setup for where I work.  The mics work between 11 and 52Vdc with 2.0mA draw.


http://shure.custhelp.com/app/answers/detail/a_id/233

Will be doing this:


I'm maybe thinking about putting a Zener back to back with the LED as well so the LED dims when the voltage starts dropping, that'll be over the two 9v batteries..... I don't know really.......

Obviously none of this LED stuff is essential but if there's no reason why I shouldn't then I will.

Cheers,
Marcus

Build Reports / Chasm Reverb and a Yawning Dog

« on: August 06, 2014, 02:13:27 PM »

Just finished these two up. Really glad I got a PCB off dead astro at diysb rather than all that wiring, thought I'd give a reverse etch a go too.  This thing sounds so great.





The Yawning Dog is for a mate of mine who's in a band called Yawning Dog, it was his birthday last week.... It's a violet rams head muff with mid pot, I used 50k for the mid control but am thinking I want something more extreme, its very subtle, suggestions? Also, thanks to Brian for the pif PCB!




Cheers,
Marcus

Open Discussion / Name that fuzz...?

« on: July 30, 2014, 10:07:35 AM »

Hey,
A friend's just sent me a little sample of a fuzz sound and was wondering what could possibly get him there be it DIY or commercial.

My initial thoughts are it could be an ugly face that could do it, but I think my judgement is coloured cos that'll be my next personal build.

Any thoughts would be appreciated.

Cheers,
Marcus

General Questions / Mudbunny 2010 build doc.

« on: July 24, 2014, 10:51:29 AM »

Hope this doesn't seem like pestering as I asked in the pif Brian did recently but wasn't sure if people would see it there....

Does anyone have the 2010 build doc?

Many thanks,
Marcus
