dannybuoy Posted April 21, 2015 Share Posted April 21, 2015 You could add a depth control similar to the Supercollider to control the amount of bass hitting the front end of the circuit! Quote Link to comment Share on other sites More sharing options...

umcoo Posted May 3, 2015 Share Posted May 3, 2015 Need help DIYers. I'm building a Poodle Pedal Parts Rat for my friends birthday. Soldered all the parts in today [not switch/led/dc power] but connected it up as in the instructions to check the pcb was working as it should. There is effected sound coming through, but there's major hum - louder than the actual sound. Anything obvious I should be checking tomorrow? I'm thinking it'll be something to do with grounding perhaps? Cheers all Quote Link to comment Share on other sites More sharing options...

It's sublime, I will never need another muff. Using 4001's for clipping in the second stage makes a surprisingly big difference. Excuse the messy wiring job, I embrace the ethos of function over form. *The Ulti-muff name is subject to change on account of it being terrible.

Sound clips can happen, probably tommorrow though, I'm still fiddling with the clipping caps. Edited May 3, 2015 by bobbass4k Quote Link to comment Share on other sites More sharing options...

umcoo Posted May 10, 2015 Share Posted May 10, 2015 Hi DIYers, I need your help again. Rat circuit is working all fine, but the LED isn't coming on when pedal engaged. LED works [tested on a multimeter], orientated the right way, resistor is soldered fine and connections at board and switch are working. Legs are touching so nothing shorting out...no idea where to go next! Any ideas? Cheer all Quote Link to comment Share on other sites More sharing options...
bobbass4k Posted May 10, 2015 Share Posted May 10, 2015 (edited) How are you switching in the LED? Are all your grounds connected? Check the switch is working with the multimeter. Also what value resistor are you using? I've put a 470k in by accident before... Edited May 10, 2015 by bobbass4k Quote Link to comment Share on other sites More sharing options...
umcoo Posted May 10, 2015 Share Posted May 10, 2015 Thanks Bob... It's wired up exactly like the link says... http://pedalparts.co.uk/docs/Rodent-v2.pdf I've attached a few pics too. [URL=http://smg.photobucket.com/user/goat_punisher/media/DSC_0361_zpsi7ez86kz.jpg.html][IMG]http://img.photobucket.com/albums/v292/goat_punisher/DSC_0361_zpsi7ez86kz.jpg[/IMG][/URL] [URL=http://smg.photobucket.com/user/goat_punisher/media/DSC_0365_zps6uonwp9p.jpg.html][IMG]http://img.photobucket.com/albums/v292/goat_punisher/DSC_0365_zps6uonwp9p.jpg[/IMG][/URL] [URL=http://smg.photobucket.com/user/goat_punisher/media/DSC_0364_zps1imnqwlq.jpg.html][IMG]http://img.photobucket.com/albums/v292/goat_punisher/DSC_0364_zps1imnqwlq.jpg[/IMG][/URL] How would I check the switch is working with the meter? It's brand new so I'd hope it isn't faulty Resistor is a 2.2k. Grounds all look good to me. I could imagine it if the pedal didn't work and the LED didn't, but everything fine except that Thanks so much for your help Quote Link to comment Share on other sites More sharing options...
umcoo Posted May 10, 2015 Share Posted May 10, 2015 Ignore me...just had a support request response from the guy at Fuzzdog...resistor should be on the board and not the actual led. Currently warming up my soldering iron...will report back asap! Quote Link to comment Share on other sites More sharing options...
Sibob Posted May 10, 2015 Share Posted May 10, 2015 Yeah, if you use the LED pad on the board, then the resistor needs to be in the CLR space, otherwise that omission means the led is getting no power (due to the path being broken). You could bridge the CLR with a piece of wire and that's be fine to leave the resistor where it is. Neater to put it on the board though. You can not use the CLR & LED pad at all, but means you have to connect the long leg of the resistor to your power source another way (with resistor in line obviously), usually straight from the power socket. Short leg obviously always goes to the switch. Si Quote Link to comment Share on other sites More sharing options...
umcoo Posted May 10, 2015 Share Posted May 10, 2015 Ok. Resistor moved to the board. Turned on and...LED doesn't light up. But!!! It comes on when I touch the LED. maybe a grounding issue? This build is killing me! It was meant to be an afternoon building it for a friend and it's turning into every weekend being a new disappointment Quote Link to comment Share on other sites More sharing options...
bobbass4k Posted May 10, 2015 Share Posted May 10, 2015 Looking at that picture, it doesn't looks like you've connected your power and jacks grounds to the board ground. All the ground points need to be connected together. Connect a wire from any of the audio jacks to the centre lug of the switch or the ground pad on the board.

Sibob Posted May 19, 2015 Share Posted May 19, 2015 Hi all, If of interest, just found this place on eBay that actually does some interesting enclosure finishes in the UK: http://www.ebay.co.uk/itm/Aluminium-DieCast-POWDER-COATED-Hammond-STYLE-Enclosure-Stomp-Vape-Box-colours-/251946723905?pt=LH_DefaultDomain_3&var=&hash=item3aa931ea41 I have a pink 1590a on the way for a build for myself, and to check quality etc. Si Quote Link to comment Share on other sites More sharing options...
Sibob Posted May 22, 2015 Share Posted May 22, 2015 Enclosure has arrived and is great quality. The standard 'orange skin' texture that you find on all powder coats, but it's even and without any imperfections. Will definitely be using these guys again! Will post the finished pedal when built.

ColinB Posted May 22, 2015 Share Posted May 22, 2015 C'mon Si, gizza clue as to what you're building. Quote Link to comment Share on other sites More sharing options...
Sibob Posted May 22, 2015 Share Posted May 22, 2015 Oh it's only a Trooper Boost to put on a mini board for me. I figure pink enclosure, pink knob, pink wiring. If it goes well, I'll do a little run in October for Breast Cancer awareness That said, I hate working with 1590a, so we'll see how my patience work out haha. Could always up to a 1590B Si Quote Link to comment Share on other sites More sharing options...
