I have two pedals I absolutly love: MXR 10band EQ and the BBE Sonic Stomp (which I know I usually get a lot of hate for).
The EQ can be used beautifulle to shape your sound, be it making it metally, sparkly or a mid boost for solos, all just one stomp away. Every band is +-12db and there is also a level and gain controll. So you can for example use a mid boost for solos, plus a boost to drive your amp extra for the solo. True bypass and all, I like it a hole lot.
Now the second thing, the sonic stomp gets a lot of hate in a lot of places. I do not know exactly how it works, it´s a phase correction thing where normally there is phasecancelation which makes the sound muddy, but the bottom line is that I still always have this thing on. What it effectivly does? It makes your sound clearer, more defined. Takes muddynes out and gives it that certain something.
If your sound sucks, it will not make it great (you only polish the turd), but it can make a great sound be amazing. It is often described as taking a blanket of your speaker, which gets you at least the right idea. It is very noticeble in clean sounds, not as much in distorted, but as you play a fender amp you´ll probably be rather clean most of the times (even if you weren´t this thing is great). A lot of people say it is just a gloryfied EQ, but I and most who tried it feel there is something more there (and most profesional reviews agree).
It is also available in rack form, called Sonic Maximizer, which is to be prefered if possible, I just don´t have a rack / space for one.
These two things are nothing gimmiky, they just improve your sound. The Sonic Stomp will just give your tone that extra "thing" and improve your tone. The EQ will give you the possibility to improve your tone and shape it in many, many ways, making it very versatile.
Just two kinda basic things I can just recommend.
I also have a Fuzz pedal on the way that should arrive in the next few days. When it does I can tell you something bout that too, might be the dirt you want out of one (I hope so ;)
