Doepfer A-124 Wasp Filter

My 1st module ever (along with an LFO, VCO and VCA) - so cheap it really is the definition of a no-brainer!

Not a fan of filters in general so I (stupidly) sold it - when Doepfer announced the SE ones I missed it so much I bought two!

The Wasp filter has its own personality, one I quite like. It is not a smooth creamy Moog style filter. This guy can punch you in the face, puke in your pocket, run off with your girlfriend but STILL come back at the end of the night and share his burger with you as he calls you a taxi to make sure you get home safely!

Your either going to love it or hate it - who am I kidding your going to love it! Nasty, spitty, buzzy little Sméagol!

Don't overlook the BP out - I initially thought of it as a LP filter and missed much of its rough-edge charm!

Pros - stupidly cheap! Noisy, cranky, angry... unique in a brilliant way!

Cons - (this hasn't happened to me but it is a known thing) Because of the way the filter is designed it puts a lot of strain on the 14-pin 4069 IC - these can and will blow. They wont do any damage, are socketted and really cheap to replace. Just buy a bunch at Mouser/Farnell and your good to go! Think of them as consumable like guitar strings and everything is fine!

I don't know how to recommend the Wasp filter higher than saying after selling mine I missed it so much I bought two more - they are so cheap you need two!

What an amazing little filter, packed with all the basic features you'll need. However, the real beauty is heard when you play with the Res - it transforming into a beast when set to full! CV1 & CV2 works really well (as you'd expect with Doepfer).

The real power of this filter is it's Res, especially when it's fully engaged and you start to experience some very rather odd but wonderful effects. I've used many filters before but now like this which makes it's something quite unique in the world of voltage controlled filters (it would be nice to see a CV on the Res but that doesn't effect the over all user experience).

Both CVs inputs are responsive and the ability to adjust CV2 is just priceless - for the price this is a real bargain. I can't wait to buy some more Doepfer filters based on the quality of this unit.

Highly recommended

This filter is brilliant. Based on the filter of the EDP Wasp, it has a nasty, gnarly sound that cuts through anything but can also be used as a reasonably mellow filter providing you don't go crazy with the settings. It loves being fed back on itself, I've had some excellent results multing the output into a mixer and mixing it back (along with the original source) into the input. Turn up the resonance and it really squeals like a beast! I think its a great compliment to any standard low pass filter in any Eurorack system. It absolutely loves frequency modulation. I've had a great time putting drums through it and modulating with an oscillator :) Absolutely astounding value. I have two.

I ordered this filter among my first modules when started buiding eurorack synth. I was fascinated after hearing some crazy sounding online demos :) But my module didn't work as it should, filter slope was very wide, it was almost useless and i just couldn't get that characteristic sounds out of it. The filter worked but was nothing special. I just couldn't understand why it's so popular. Then I sent it back for a repair, Thomann staff was very helpful and arranged everything very quickly and I got it back in about 2 weeks. Then the real fun began :) This filter is now one of my favourites and i even prefer it over some very expensive ones! Search for some YouTube demos of this module before ordering to check how it sounds, it's just awesome! Doepfer kicks ass!

Bought this filter on a whim really, had heard from various sources that this was a filter with plenty of unique character. These sources were definitely right! The filter can be as polite or aggressive as you need it to be. Low resonance settings give you more subtle results but where this filter really shines is on high resonance settings where you can get a multitude of unpredictable driven tones. As has been previously mentioned this filter will not self oscillate due to built in limiting so if you need this feature you will need to look elsewhere. I would highly recommend this filter as a compliment to another more neutral & cleaner filter.
