Running through my 1x12 guitar cab I found that my flip top patch didn't have quite as much "life" as I was able to get through the FRFR cab. I've modified the patch to optimize to for the guitar cab but it was still missing a bit of something. I was already running the vintage pre-amp, an easy way to add a bit of life to a patch but this morning I tried adding a second vintage pre-amp just to see what it would do. The difference was quite dramatic, especially in the high end. A bit more sparkle and body but the difference was really obvious.
