I have a GEB-7 that has really helped my tone out. But there are some frequencies on the GE-7 (guitar version) that I really would like to have control over, namely (200, 1.6k and 3.2k). I'm going for low-mid presence and thump with some of the edginess that the upper mids have to offer. With the GEB-7, I feel like 120 is too low of a start for low mids while 400 is too high. I 'd like to make a softer curve of 120-200-400 boosts to tackle the low mids. I'd also like to boost 800-1.6k-3.2k while dropping the less pleasing 500 slider on the GEB-7. I'd like to roll off 10k (GEB-7) and 6.4k (GE-7) and have the ability to play with color high-mids @ 3.2k (GE), 4.5k (GEB, and 6.4k (GE) with the intention of slightly boosting 3.2k to help with the perceived grind and shimmer and rolling off the other frequencies. I know that is totally theoretical and that I may have serious phasing issues to wrestle with. But I'm not totally satisfied with the level control that I can get out of the GEB and was wondering if I would be better using it in tandem with the GE or just scrapping the whole eq pedal idea and getting a 30-band Rane equalizer. I'm using this for tracking in the studio but I'd like to be able to translate whatever eq system I arrive at to be suitable to fit into my live rig which consists of: Sansamp RBI DBX 166A Aphex Aural Exciter when Needed Rocktron Gainiac as a switchable tube overdrive unit (the overdrive sound is 100% worth it to me to have this thing in the rack) and a QSC Poweramp I could run two eq pedals in front of the RBI or I could try to score a rackmount eq and stick it in before the DBX. As a said though, I'm looking for flexibility and the ability to tweak in a sound that I like both on stage and in the studio.
