JC, Since I got the mod done last week, last night was really the only night I have been able to really crank the amp up during practice and see how things went. I was pleasantly surprised about the mod. Usually I have my orange and red channels set about 9:00 on the respective masters, with the red being slightly higher (for solos), and my loop master is usually set at 9:00 also (I know, it's get pretty loud at rehearsals). Last night after the mod, I had to turn my loop master down a bit to equal volume with my other guitarist (who also has a newer 3ch triple recto). That was a nice surprise as my amp didn't seems to work as hard to achieve it's usual volume and tone.
As far as the tone is concerned, fairly same as before, although I felt like it was slightly more crunchy than before but slightly more bright. I decreased the treble a bit and evened things out and it sounded great. The effects for me seem the same as before, but now I have control over the "volume" effects like vibrato and tremolo, since there is no longer a blend of the original signal and the fx signal at the amp (parallel loop). I do like the fact that I can control the mix of effects in my unit from patch to patch instead of a global mix at the amp. This give me much more control over each individual patch and effect I am running within my processor.
So far I am happy with the modification. If you have a digital effects unit such as the G-Major, I would probably do the mod if you need more control over your effects that are placed in your loop. It's super easy to complete and totally reversable! If you have any other questions, let me know! I also made sure to take a lot of pictures of before and after the mod for future reference, I can email them if you like...
