regarding the volume setting for unity gain before and after the tube change, it is pretty dramatic;
with the stock 12ax7’s, I had the Wiggler’s volume knob around 9:00. After the tube swap, I have the volume around 2:00! With the intensity knob zeroed, the signal sounds identical to the non-wiggled signal, so that’s good- I do think it’s unusual it took such drastic changes to make the unit function like it should.
Brian, you say your unit is slightly too edgy? I’d say you wouldn’t need to go all the way down to a 12au7 if you can use words like ‘slightly’. the level of distortion I was getting from the Wiggler was like having a overdrive box active- not subtle at all!
I should add that now that my Wiggler is working, I love it. the vibrato circuit come closer to a Magnatone’s than any other fx unit I’ve found, and I also prefer the tremolo over the one in my Fender Deluxe.
JamieGarnerMembermy wiggler made a distorted mess out of my signal. in the end I used a 12au7 tube in v1 (closest to input jack) and a 4024 in v2- the signal is perfect now, with the only distortion in the signal being what I dial in from other pedals or the amp.
the 12au7 has a gain rating of 17 compared to the 12ax7’s rating of 100, so it took some serious power reduction to clean up the signal. I started with a 5751 and worked my way down to the 12au7.
v2 was still distorting with a 12ax7, and the 4024 (equivalent to a 12at7, gain factor of 60) was the first tube not to distort.
is there a calibration or biasing control inside the case, and the occasional Wiggler is too hot, or do they all double as distortion boxes?
anyway, my Wiggler sounds fantastic now.
