Im not too sure what to add to this convo, except that the sonic stomp sounds like a real nice addition to improve your tone, but may not warrent the gold pieces you put into it. Amp will ultimately improve your tone i think, and second place comes pickups/guitar. Of course these are pretty expensive and if your not keen on saving up the whole hog and getting one of these, a sonic stomp might be good for now, and will also make a nice improvement when you do upgrade ur amp and such. I always thought the sonic stomp was more of a tweaking pedal to make slight improvements but ive never tried one myself either so i could be brutally wrong :oops: .
As for a distortion pedal im gonna urge you to go for it. In the short term, a distortion pedal will boost your distorted tone a mile if yor amp isn't giving the candy. I have a marshall 15 watt. I stuck a £60 Uber metal pedal infront of it and now i can get some real nice tones out of it. Loads of versatility too. Its great for tone on a budget in my opinion. a valve amp will always be the real dogs bollocks, but to fork out for a 50watt valve amp or something just for an improved distortion is a little of an overkill in my opinion.
Basically id go for the distortion pedal for sure, but think over on the sonic stomp a little more. Im going to get one on a bit of a gamble myself (at some point in the future)
Just some thoughts, sorry if they are ill-presented :lol:
