The good old ODR-1 is a great pedal, and I agree on the low end. If I recall correctly, I turned the spectrum knob up until the bass got too much, then stopped.Got a chance to try this, and an ODR-1 with bass at a buddy's place.
He'd only ever used them on guitar.
When I said they had some buzz on TB, we tried'em both.
The Greer is quite low gain, but adds this nice "sparkle" to your tone.
The nobels, has a massive amount of low-end on bass. Too much almost.
However, it's tone was enough to convince me to (finally) pull the trigger on the mini2, with the external bass-cut dial, so I can fine tune it.
The Wampler Belle was the same in that regard.
