Re: Talk to me about the Fulltone Fulldrive 2, please.
They're similar, and both are rated as the top clean boosts by most pedal geeks.
The Klon kind of enriches the sound of any amp it's plugged into, and it's like turning up the gain or volume on your amp. Very neutral, with a slight boost of every frequency, not just the mids. Kind of like a Sonic Maximizer with a gain and volume control. It has a nice bouncy, tubey quality under your fingers.
The Coldfusion seems similar when used as a clean boost, but has more crunch and growl as the gain gets turned up. It's more aggressive sounding compared to the Klon. The only way to really describe that difference is that a Klon is more 6L6 like, and the Coldfusion is more EL-34-like. The Coldfusion would work better as lead tone because of it's crunchy gain. The Klon works better as a boost. When used as a true overdrive, the Klon is more Robben Ford, and the Coldfusion is more Billy Gibbons. If you don't need a dual mode pedal, I'd get the Coldfusion. Look it up on harmony.
