I’m stoked you like LEGO so much, it’s nice to have a passion. One of mine is BUILDING interesting signal chains. If you’re using loop switchers (creating little duos/trios/etc of pedals) and parallel blenders with wet/dry kills /drones/beats/layers, not even getting into wet/dry or wet/dry/wet rigs...you are literally BUILDING your sound. Any change would create differences, it’s a choose your own adventure for your guitar signal- with limitless combinations that are each unique. If you can’t distinguish between all of that and playing with legos or for that matter: plugging in a few pedals with power supplies and patch cables into amp.....I don’t know what to tell you. I mean- some people BUILD sandwiches, some people BUILD mysteries like Sarah MacLaughlin, I happen to BUILD interesting signal chains.
