So I made a switch from my long time Vetta combo back to my old re-tubed 5150 and 4-12 cab. Love the Vetta.. but wanted to go back to tube. Problem was I had no clue where my old pedals went and long ago dismantled my rack gear. So I got a used HD400 on a heck of deal, but didn't really need it for the amp models...so I got a used M13 because I want the 5150 tone. The biggest issue I can't seem to fix is how to have a pedal set up to boost for a lead solo. Back in the day I had an old Boss EQ pedal flat that I had the gain up on ...and stomping it gave me the boost to be heard on solos. I figured one of the Comp settings would allow that... which is what I used to do on the Vetta. But I can't really hear a difference in volume level when I increase the 'level' of the FX. Am I doing something just ridiculously wrong? I don't want to have to hit 3 pedals for a solo...a boost plus delay etc.. I also bought the LIne 6 expression pedal.. I assume I can use this as a volume/wah? I'm almost embarrased asking what seems like simple questions....but I don't have but a week to figure this out before another gig...I love the m13... def gives me what I need... but I gotta have a boost thing happening... surely it can be.
