Greetings all. I am new to rack mount options, so I need a little help. I recently disassembled my pedalboard because I'm playing in a metal group and need very few effects. I got rid of my Sansamp Bass Driver and opted for the RPM. After reading the scores of reviews here on TB, in hindsight I should have gotten the RBI, but I digress. I'm also running a Line 6 G90, wireless and a Korg Pitchblack Pro Tuner. So my question is this: If I have a limiter built into my amp, do I really need a compressor/noise gate for my rack? I understand at times the RPM or RBI for that matter may get a little hot, but will my amp limiter compensate for that? Any help will do, I don't want to waste time buying too many components.
