Okay. I'm confused and I admit it. When I got my Sparkle Drive it behaved. But just lately it has developed a really loud 'clack' when I step on the switch. I was putting up with that because it sounded so good as a boost OR as a Tube Screamer equivalent (ish). But after I got the GigaDelay, it's been misbehaving worse. It just doesn't sound right with the delay. It gets kind of ugly and definitely kind of wierd. THe actual tone of the pedal seems to be changing. Is this a normal aging thing that I can take it to a shop for, or is something breaking and I should look for a new Sparkle Drive or something similar. Do these guys just not play well with time-based effects? Help.
