Members warioblast Posted February 19, 2010 Members Share Posted February 19, 2010 Roger Mayer 9090A wah kit, showed up this morning. The previous owner cut the rubber stops so I kept on hitting the on/off switch The rotary switch gives 6 wah sweeps. My first impressions: It sounds like a cross between a vox / crybaby & a WH10. (as far as I remember the WH10 tone). Rather flat & dull on a clean sound, it gets better with dirty tones. The more trebly position has nice Jimmy Page vibes. More on this later.

Members wilsoneffectsll Posted February 19, 2010 Members Share Posted February 19, 2010 You should replace that plastic switch with a metal one. The plastic ones seem to break over time. I've learned this from experience. what kind of pot you got going on there? Maybe swap that out too. Just my 2 cents. Link to comment Share on other sites More sharing options...

D*A*M use them in their Colorsound clones. Link to comment Share on other sites More sharing options...
Members warioblast Posted February 20, 2010 Author Members Share Posted February 20, 2010 Are there any owners ? Link to comment Share on other sites More sharing options...
Members warioblast Posted February 20, 2010 Author Members Share Posted February 20, 2010 Hey Kevin have you ever seen such an inductor before ? The coil is splitable. Link to comment Share on other sites More sharing options...
Members Instrospection Posted February 20, 2010 Members Share Posted February 20, 2010 Looks great! I like wah with alot of flexibility....I find that the Q of the mids is sometimes off, or that the sweep isn't to my liking. I'd done a bunch of mods to a Crybaby original reissue (buffer removal, installed a bunch of variable resistor pots for voicing and volume changes) and i'd found that even just adjusting the notch setting on the pot helped out alot to get it right at the point of not being icepicky in the mids, but also not dropping out in volume at the treadle's least amount of mids in the sweep.

Members wilsoneffectsll Posted February 21, 2010 Members Share Posted February 21, 2010 Which inductor is splittable? I've never seen that before? The one in the dik looks like one of the inductor kits you can purchase and wind yourself or possible an arteffect or stuart caseldine inductor.

You can see 9 pins on the back of the pcb, top right of the picture. I was like "WTF !" when I first saw this. Link to comment Share on other sites More sharing options...
Members warioblast Posted February 21, 2010 Author Members Share Posted February 21, 2010 The rotary switch, 2 poles 6 ways, mixes coil-tap & sweep caps. You got 3 positions with "low coil" and 3 with "high coil".I'm going to mod it to 1 toggle switch & 1 rotary 1 pole 12 ways to really hear what the coil-tap does.

Members wilsoneffectsll Posted February 21, 2010 Members Share Posted February 21, 2010 So assuming it's a 500mh inductor you could split the inductor and get 250mh? That's what the old gray vox wahs that Page used had in them. What does it have for a Q resistor across the inductor? As those old voxes didn't have one. Is there 2 different coils inside the inductor then in series but you can break the series loop? Link to comment Share on other sites More sharing options...
Members warioblast Posted February 21, 2010 Author Members Share Posted February 21, 2010 It has a 33k Q resistor. Looking at the inductor, you can see 3 copper wires going to the 3 pins I circled in red. The 2 pins on the right are connected to the rotary switch and the other pin is connected to 1 side of the 33k resistor. Here's the manual for the kit: http://www.roger-mayer.demon.co.uk/9090A%20Wah%20Kit%20Installation.pdf Link to comment Share on other sites More sharing options...
Members wilsoneffectsll Posted February 21, 2010 Members Share Posted February 21, 2010 So the 33k resistor isn't switched in and out. That's a pretty in depth kit! Me thinks me digs it. got any clips? Link to comment Share on other sites More sharing options...
Members warioblast Posted February 21, 2010 Author Members Share Posted February 21, 2010 Unfortunately I only have an old camera to make clips, it wouldn't do justice to the pedal. It's confirmed, the pedal sounds like ass on a clean sound. I wonder if Roger Mayer sells those inductor at retail. I really like to hear it in a wah with more vintage oriented parts.

Members warioblast Posted February 22, 2010 Author Members Share Posted February 22, 2010 Got a reply from RM. They don't sell these inductors. Link to comment Share on other sites More sharing options...
