Maxon SD-9 Sonic Distortion

I kind of have a love/hate relationship with this pedal.
I definitely like it, but ever since I changed my pickups I found that on some amps I can't seem to find a sweet spot on the tone knob.
I already knew the highs can get out of hand pretty quick, but I've always found a way to tame them. Now, not so much...
It is evident that it just doesn't get along with my new pups, but I just wonder how common this issue might be with other pickups/amps.
Still, it's a great distortion pedal (the bass response is excellent), just make sure it goes well with your setup.

Featuring the incredible build quality thats such a credit to Maxon this is a beautiful pedal..but theres a but....
Described as "Sonic Distortion" its really more a "Sonic Very Crunchy Different to a Tubescreamer Overdrive" albeit one that preserves nuance and detail well....but it lacks the tremendous "foldback" you can easily get with an OD9...its quite a "stiff" pedal which is lacking sustain/feedback....though give it a kick with an OD-9 and you're away....
So I find it works better with Humbuckers and put one of the new Ibanez SD9M pedals in the chain for single coils...
Downsides..its not the same value for money as the OD-9 as its more limited in its application...and it has that odd strongly sprung switching mechanism which needs a very firm boot to engage and which can then disengage if you wait just fractionall too long before lifting your foot...
Verdict?...unlike the OD-9 which seems to work brilliantly with any amp/guitar pedal the SD-9 ismuch more specialised...I've had it maybe 6 or 7 years and only recently found its niche...a peculiar flavour of pedal for sure..

I tried this pedal since Michael Landau was using this a lot and he knows tone. But also I noticed that with some amps it sounds really sweet and smooth while on other amps it sounds fizzy and harsh in the upper mids.

So first of all, it seems to love tube amps.
And most of all, it loves certain speakers that tame the nasty fizz but still bring out the guitars musical overtones. Landau plays with G12-65 speaker, I use Marshall G12 Heritage speaker and these speakers seem to match the pedal nicely.

Also responds well to guitar volume knob, might even smooth out when volume rolled back to 7-8.
