I've compared the stock GE-7 with your modded GE-7 na. Got to gig with the modded pedal last night.
Works as expected. Nice fat boost (if thats what you're using it for) for solos.
At gig levels, and the way i set it, its just like a regular GE-7. Last night i used my Edwards e-lp-98lts with skatterbrane A2's into a keeley rat then GE-7 then some small 1x12 laney (kung anong model man yung nasa route 196). Like I said, it worked just like its supposed to, just like a regular GE-7. Its an EQ pedal anyway. No "it made me sound 10x more musical" miracles here.
Plus, the way i set it isn't extreme at all (400=+3, 800=+5, 1.6k=+5, 3.2k=+3, the rest at 0, level anywhere between 0 to 5 depending on how the amp reacts to the boosted frequencies) so yung gains of using higher quality components isn't that obvious. I use it massage the right frequencies into place as opposed to hammering them into submission.
Those gains I only saw this morning. I made 3 vids. I used a Burny lc-70rr with SD '59/JB pups. I kept it on the JB (the noisier of the 2 pups) the whole time and didn't play at all. The guitar was just there to introduce regular guitar electronic noise. The amp is my old Marshall 8040 on the clean channel cranked up to 8 (which is why i couldn't do any actual playing; maaga pa e). Everything is connected with cables I made myself (klotz cables and neutrik connectors). I tested the EQs 2 bands at a time, all the way up (which is the wrong way to use EQ for guitar). Level at 0.
So, here are my err... findings:
1) 6.4k and 3.2k - halos identical. both pedals sounded hissy. which is to be expected. you're boosting white noise frequencies from the guitar electonics and cables after all. medyo finer grained lang yung hiss from the modded pedal pero hissy pa din
2) 1.6k and 800 - here you'll start hearing the difference na. at these frequencies (where most guitar's "meat" is and the frequencies normally boosted for solo work to cut through a dense mix), the modded box was considerably more quiet here.
3) 400, 200 and 100 - again, you'll immediately notice how much more quiet the modded pedal is at these frequencies. in fact, at these frequencies, yung hiss you hear from the stock pedal is almost non existent on the modded one.
you can actually hear these differences dun sa vids i made with my crappy digicam and its crappy built in mic.
so yun. arjin, good on ya mate.
i'm keeping this.
i'll post the vids in a bit or send them to you.
