Spaniard here, with experience making fresh gazpacho.
First of all, I must tell you that there is not a recipe for “gazpacho” as most people understand the term: At most, you have “guidelines”. There are as many recipes for gazpacho as people making it. The only constants are fresh tomatoes and olive oil. Also, the preparation is ridiculously easy.
The best way to get a nice gazpacho that you will like is to take those “guidelines”, run with them and experiment until you get what you like! 
I will tell you how I myself make gazpacho… BUT… Please do not take what I say as a “recipe” that has to be faithfully followed! Just get the “idea” behind it, and play with it until you get what you like.
So, without further ado, here is how I make gazpacho.
GAZPACHO FOR ROUGHLY 6 PEOPLE:
INGREDIENTS
-About 1 kg (roughly 2 lbs) fresh, ripe tomatoes. The softer the better (without them being too soft, of course).
-A couple of cucumbers
-One green bell pepper, one red bell pepper.
-Half an onion
-A clove or two of garlic
-Hard bread (Bread from yesterday or a few days ago which has become hard). Let’s say about 4 to 5 slices, or 1/3 of a French baguette.
-Olive oil, vinegar, salt to taste.
-Water and, if desired, some ice.
PREPARATION
-Leave the hard bread in a bowl of water for about 15 minutes or so, to get it thoroughly soaked.
-Cut the vegetables in chunks. Keep a few bits of pepper chopped into little cubes to decorate afterwards.
-Put them all in a mixer with a bit of water.
-Shred everything together very finely with the mixer.
-Add the olive oil, the vinegar and the salt to taste (do not skimp on the oil, but watch for the result not to be too oily; careful with the vinegar and the salt to they don’t swamp the taste of the vegetables).
-Mix again for a bit.
-Add the wet bread into the mixer and mix together to make a homogeneous paste. Regulate the liquidity of the result by adding more water if needed. If you want the gazpacho to be “instantly cold”, add ice cubes instead of water and mix.
-Serve into bowls and decorate them with the chopped peppers.
Enjoy and take very cold! Excellent in a hot summer day.
I hope this helps!
