I have a Dunlop GCB-95 Crybaby Wah I've had since new in 1994. The pot was getting noisey ( Scratchy ) sounds. I replaced it and fixed the problem. While I was at it, I also replaced the original inductor an N30. I replaced it with a yellow Fasel. I also took installed a trimpot for adjusting the "Q". After adjusting the Q using my Strat Special and a Marshall JTM1H it sounds very good.

You are to be commended for doing your own work, and for producing such top-notch results.

This is what it's all about!

Thanks Spar! I used a digital multimeter set at 20 K ohm. I turned the trimmer until it was .18 ohm. After I plugged it in I got a fantastic vintage wah tone. Before it was noisey I was happy to plug it in with a dirt pedal, fuzz, distortion, Od, etc. Now on it's own it has a great tone. I like boosting it, it really makes my Marshall DSL5C come to life with a really sweet smooth tone.

JAC,

I have read where some guitar players will play some songs with the Crybaby clicked on, but the pedal position left alone and in a certain 'sweet spot'.
(In other words, they aren't actively manipulating the pedal, but rather just enjoying the way the guitar sounds with the pedal set at just a particular location.)

Have you heard that too, and do you ever fool around with such sonic experiments in your playing?

I had a Crybaby 535q for a year or two, but ended up selling it to a local pedal maker who coveted it.
(And I honestly wasn't using it much, except for the occasional boost function.)

I wish now that I had spent more time with it!

I've used the wah in a one position spot for the tone somewhat at times. Frank Zappa and other artists have used it this way also. Frank was also known for going off with the wah like on some of the recordings on overnight sensation. If you decide to get another wah I would go with the MXR Custom Audio Electronics (CAE) MC404 dual inductor wah. I also had a 535Q which I had a few days and took back before I got the MXR MC404. There is one great demo on youtube where some kid from England compares his older 535Q and a new MXR MC404. That was what convinced me to take back the 535Q. It cost about $20 more but way well worth it. After I had my new MC404 was when I became brave enough to work on my old Crybaby GCB-95. I figured if I messed anything up I still had my cool new MC404. Both the red and yellow Fasels sound great on the MC404. I have left the "Q" settings on both stock from the factory setting because to my ears they both just sound right to me. If you feel like it you can adjust the "Q" internally. On the mod that I did with my old Crybaby I used a 28 turn trimpot or trimmer I installed. I'm not any kind of electronic Wizard. I just went by suggestions from a friend online from a gear forum I'm on. We both posted pictures and such. I decided to do the yellow Fasel mod because the yellow Fasel in my MC404 sounds so good. Now my old Crybaby sounds even better than it did when it was new. As I've been posting if you decide to get another wah, do yourself a favor and check out the MXR MC404. You won't be sorry.

By the way Spar, for what it is worth, some say the older 535Q sound better than the newer ones. The one I had sounded "so so" to me compared to what I have now.
