I'm not looking for distortion, but for gain. My amp is no where reaching its max potential with the volume knob on max. I tried plugging my bass into a guitar distortion pedal, kept the distortion gain to minimal, so as it wouldn't actually distort my bass. The volume level was WOW. I got max power at 7 on my amps power knob! I know they have bass preamps that could probably do a better job at this, but they all are priced somewhat out of my budget. Guitar distortion is much cheaper. Are there any possibly negative effects from the guitar distortion? What do you recomend I do? Should I fork over $40 for a Boss DS-1?
