Ravon,
I don't get why you'd want an EQ pedal, but it may be because I don't know where you are starting from 'along the Tone Trail'.
So, if you don't mind, what make and model of amp do you use now? Do you currently use any FX? If so, what? How are the FX set?
How loud do you play? Are you currently getting a heavy distortion/high gain sound out of your guitar and amp or are you just
saying that you don't like heavy distortion in general and want to find something else to aspire to?
I've had MXR 10 channel EQ pedals. Not bad if you need one to boost or cut a certain part of the sound spectrum.
The gain control is nice if you need it, but there are plenty of FX pedals that do that.
If you use an MXR, you're also introducing a transistorized box into your tube chain. Sometimes that can suck tone from your
'Sound' (just like playing through a Roland tuner all the time, though this falls under the heading of 'little things can make a difference').
If you don't want to do all that, I understand. So, here's my quick opinion based on no info:
When I hear somebody say they want to sound like Wes and SRV put together, I'm thinking they want a sweet humbucker sound but also want to be able wail when they need it. Sustain doesn't come from an EQ pedal, although it might come from a gain control on an EQ pedal. Look into clean boost pedals, something that will hit the front input stages of the amp a little bit harder and kick it over into more of an overdriven sound.
Oh, and good luck with the Quest. It never stops does it? :lol:
