I was recently in a band that played dark metal. In fact, a lot of my early musical influences have been metal, all through the 80's. My pedal board is very simple. Boss TU 3, MXR Bass Distortion, and Ampeg SCR-DI; of course the DI is last in the chain. My preamp is always on, and I use it with the Scrambler for gritty, dirty Bass; I also use the Bass Distortion with the preamp on. I never see the need to combine Scrambler and Distortion; it's one or the other. No matter how many times, I look at other types of pedals, Envelope Filters, Chorus, Fuzz, Octave, etc. It doesn't seem to fit my style or desired sound. True, it would be fun to play with an Envelope Filter or a Flanger, but not sure I would ever use it on a stage. I've thought about a Compression pedal, but I utilize the compression on my amp at about 5:1; this sounds good to my ears, and it acts as a limiter, keeping me from clipping the amp. So my question is this: does anybody have suggestions for another must have pedal, that would enhance my playing? At this point, I'm willing to assess any make or model of any type of pedal. Any suggestions or ideas of something I'm missing? I'm willing to be sold on something.
